How would I go about taking care of a wood clarinet?

I got a great deal on a Selmer Signet Special clarinet on ebay earlier this week. It's in great condition (no chips or cracks, corks and pads look good, and it plays with very little effort), but I'm still going to take it to my tech as I think it would still benefit from a tune up. It most likely needs to be cleaned too.

So what do I need to know and do to keep my clarinet in good condition? I've only ever owned a plastic clarinet, and I just swabbed it out every time after playing it. Is there anything extra I'd need to do with the wood clarinet?

Also, how would I go about cleaning it? Or would it be better to leave that to a professional?

Thanks in advanced for your help. I appreciate it!

Presumably the only things you have to worry about are rapid humidity and temperature changes; it should not crack otherwise. I am not familiar with clarinet maintenance but for bassoon I have to have the instrument's bore oiled every year or so coinciding with overhauls. You may have to do that, or not, I'm not sure. You shouldn't really need to "clean" it; anything like that would be handled during a complete overhaul/restoration. Make sure you swab the instrument out before you put it away, every single time, no exceptions, and be wary of temperature differences between the inside of the instrument and the outside; I.E., blowing hot air into the inside of an ice cold clarinet (below 60 F). If you leave the wooden clarinet with moisture inside, it will soak into the wood and rot in addition to ruining the pads.

Like saxophone, you should bring it in for a checkup every year (6 months or less if you beat on it), make sure the keywork does not get any undue wear in the action, make sure the keywork is oiled, etc. There's nothing too crazy! Best of luck

Nobody has any proof that an old clarinet will ever crack in time, especially an old one which has gone many many times over a cyclus of being wam and cold, wet and dry, played and unplayed, there is no proof which has determined that two identical clarinets ( such a thing, by the way doesn’t not exist because each piece of wood is individual) , one exposed to the aforementioned cycli before will develop a crack and one which didn’t wouldn’t do that!

There is also no proof that if they are not oiled this will crack the wood or that oiling does anything to the bore of clarinets because by their nature the woods used for clarinet is non oil absorbing since ti is hardwood which has oil saturated natural fibers (unlike Boxwood which is the wood used in early clarinets).

Some folks will sell you expensive oil drenching sessions as a part of a complete dismantling of the clarinet and overhaul which do nothing at all to your clarinet and a lot to your pockets. So others also would you believe that old clarinets lose their soul and the legend has developed that every now and then you need to buy a new clarinet because old clarinets are blown out.

Anyway.

Most of us do oil the bore simply because it costs almost nothing to put a few drops of oil (which oil is another can of worms!) on a soft brush or cloth and pass it a couple of times in the bore. Most of the times if any “cleaning" should remove traced of bad oiling done before with oils that have turned into gunk into toneholes, for example.

Clarinet haardwood is a completely different thing than a bassoon made of soft wood and doesn’t need to be treated the same way.

As I mentioned before, the high oil content of a healthy bit of African Blackwood heartwood, coupled with it's dense, extremely fine grain, means that the oil absorption will be extremely negligible to none.

Furthermore, many commercial so called "bore" oil" products contain mineral oil and some synthetics which do nothing to help the wood. If you insist on oiling, pure Almond oil is preferable.

Restoration of a piece that has been exposed to prolonged dry heat to the extent that much of that oil has leached out over time might incorporate oil applications. Never the less, as I mentioned above, there has been extensive study of this practice in the Pipe making trade (bagpipes) which is at least as old in it's use of this species of wood as Oboe and Clarinet production, and the general consensus among the professional makers regarding actual bathing of the wood is... don't do it.

Tis is one of the best balanced articles about it I am quoting because, invariably, people don’t follow links (or use the search engine!):twisted:

Drowning in Oil

Contradicting Views
There are but many wood wind makers who are convinced and who will tell you that the corpus of a clarinet or oboe need from time to time to have a bath in oil. For maintenance they completely disassemble the instrument, remove all corks and pads and put the keys into a galvanic silver bath and the wooden parts into an oil bath. The duration of the oil bath varies from some days up to two weeks. Other manufacturers do disapprove - and they give reasons, why the oil bath does not make any sense (from their point of view). Yes, some even state that it will affect the sound quality of instruments in a unfavorable way. The tone will drown in oil. So - who has got it right and who is wrong?
There is a simple answer to the question, but it needs some insight into the matter. There are good points to both sides, as always. Let us first focus on the basic question:
Why do some say oiling is good?
Wood is a living material, that consists of a mixture of organic substances and minerals. Next to these the water that is bound in cells and gaps between cells is a very important factor. Before we can build any instrument parts from the wood (whatever type of wood it is) you have to let it pre-dry. This can be achieved by storing it over long periods, that is years, first in the open, then in special drying rooms or - today, much faster - in artificially climated drying chambers. Drying will reduce the water content of the wood and so the wood will shrink in volume. The idea of drying is that you want to reduce the amount of water in the wood to a degree that will later remain more or less constant, because
fresh wood - that is wood with too much water - would loose volume, the mechanique built (screwed) into the wood would create tensions, and the key system would not work properly or even the wood might crack.
dry - too dry - wood might suck up humidity from players breath in the bore and swell. This would result in blocked tensions, problems in the mechanique and - again - cracks.
This leads us to the purpose (and the only purpose) of oiling:
It shall prohibit or at least control the change in humidity in the wood. There is no doubt it makes sense to protect the wood from an excessive humidity. So what could be wrong with the oil bath, if it can achieve this goal (and everybody agrees that oil will do that)?
To answer that question we must know more about oil and its effects.
From the wood worm's perspective
Until now we have looked at the issue from an outside position. Now just do follow me into the inside of our instrument, and feel into the wood, looking at it from the wood worm's perspective. This microscopicaly small "wood worm" is feelin' good within "its" instrument (especially when you play Mozart!). And - more than anything else - it loves the vibrations, that make the instruments body swing and then its own body. But in order to make the most out of this feeling the wood worm must press its head against the wood and hold himself with his tiny feed at the walls. Only then he can swing. Otherwise the walls would just shake and the worm would become sick from being shaken from one side of his hole to the other, resulting in serious headache, even with Mozart...
An oil-drop will feel the same. Since there is not handle or hook to which it can hold itself, it can not join in with the instrument's vibrations. The drop will rather be thrown here and there - and will work like a microscopic dampener to the swinging: Each movement and friction will reduce a littel of the swinging energy. Especially the very high frequencies will suffer from that; all the little drops together will muzzle these nearly completely. In the end all the tiny drops will absorb considerable amounts of energy, and especially in the high overtone range. The result will be a much duller sound than before oiling (some will use the euphemism "darker").
In general nothing new
Some instrument makers know about these facts in detail. A well known wood wind instrument maker acts like this:
The wood will be stored in the open for eight years (at least it was like that not so long ago). Then it is put into a big vacuum-container, in wich the pressure of atmosphese ist reduced quite far. This will make all fluids that can evaporate to leave the wood, including the water (in form of steam). The chambers with wood that is dried out like that will now be filled wiht oil, and the wood will suck up the oil like a thirsty sponge.
Now the wood will rest for two more years (at least such were the standard procedures - by which I want to say that it might be different now). Not before the end of those two years the wood will be drilled and transformed into instruments.
Instruments made this way are known to show problems in the beginning, they just don't "take off" that easy, but after some years of proper treatment they will become better and better. The sound will improve and be more free. What is happening there? Shouldn't we be able to build instruments, that are perfect from day one on?
Oily details (oils ain't oils!)
Now it is time to learn a little more about oils. You have to differenciate between two larger groups of oils, that haven't got much in common except for their name. Chemically speaking they are completely different.
a) Mineralic oils
These oils are mixtures of carbon-hydrogene with 8 to 20 carbon atoms and make the most prominent part of crude oil as it is pumped out of earth and used to make petrol and gas (to end up as Diesel or gas fuel in cars or as greasing lubricants, for example). You can't eat or drink this stuff or it would kill you.
b) Organic Oil (from plants or animals)
These are, chemically speaking, glycerin ester, saturated or unsaturated carbon acids (triglyceride). You could think of these oils as fluid fat. These are the ones a wood wind instrument builder uses, and therefore I will treat them in more detail.
A triglycerid will look somewhat like this:
Bild: Triglycerid
There are three fat acids hanging at a glycerin-molecule. The fat acids could be of quite different nature. You find two types:
saturated fat acids with only single junctions between the carbon (C) atoms - this is the one upper group (1)
unsaturated fat acids like oil acid or linol acid with double-junctions between Cs - the lower groups on the picture (2)
The latter are called “unsaturated” because the double-junctions between C-atoms have not been saturated with H-atoms (each double-junction could and will break up into a single junction if there is an H-atom that could be bound by the molecule - this process is called saturation).
The unsaturated fat acids are what matters in the oil. Double junctions are less stable than single junctions - it comes as a surprise to those of us who did not visit chemistry classes. The process will start easily if oxygen is available. Especially this will be accelerated by light (even more under UV-light). The oxidation will produce connections between oil molecules in all three dimensions - so in the end the molecules can't move against each other any more and so become solid. This is very important for the instrument and we call the process:
The Resinification
It is very difficult to define resinifying in detail, but one could as well call it drying and sticking. All oils containing non-saturated fat acids will sooner or later go this way and become solid.
You probably know what happens if you leave a good salad oil alone in a bottle in the open for some time, don't you? There is a rest of HARZ in the neck. But some oils do this faster than others. Some do never at all, this is guaranteed. But these oils are worthless from an instrument builder's point of view (and for food purposes, too).
You will probably remember the sticky stuff in the neck of your bottle of salad oil that you left open in the sunlight, don't you? This stuff is resin. Certain oils will start to build resin faster than others. Some never ever will - guaranteed. These oils will never become smelly, and they will never dry. But they must not be used for wood wind instruments. These oils are saturated oils, like paraffine oils. They are mineral oils. Producers and companies who sell these oils will forgive me if I strongly advise you not to use these oils. They will give the wood a certain cover against humidity, but from an acoustical point of view they are bad. And then these oils will not stay in the pores of your instrument for long, but being washed away by humidity pretty soon.
Studying old books for a "how to" (that is books older than the widespread use of mineralic oils) you will usually find they mainly mention linseed oil and not much else. For hundreds of years this oil made from linseed (flax) which was always available and rather cheap was used for many wood impregnation purposes. The old books tell you that you can only use the oil when it is fresh. When it gets old, it will become smelly. This is due to the reaction of the oil; long molecule chains will break up into smaller, unsaturated fat acids, some are quite smelly. Most of us will know linseed oil in a modified form called firnis, which is used in painting. But firnis contains some metal oxides (cobalt, mangan, lead, cadmium) and these are poisonous. We rather use the native, cold pressed, fresh linseed oil, yes, just the very same stuff people pour over their salad (if they like the taste).
Except from linseed oil there is at least one oil as good as linseed oil, and that is hemp oil. But since hemp is banned in the U.S.A. (cannabis is hemp) it is slowly to take on now.
There is one more point in our search for the optimal oil: Without air (that is oxygen) there will be no effect! As you have read above, the drying process needs oxygen. That means an oilbath (even a linseed oil bath) can't be optimal - there is nearly no free oxygen in the oil. Looking at it from the wood worm's perspective the oil should make an ultrathin film on all cell walls leaving some way for oxygen to come in in order to fuel the resinifying process.
How then can I bring in the oil deep into the wood without clogging the fine pores with the resin - because at the outer openings the resinifying will start (very much like in the salad-oil bottle's neck)? The solution is a solution-aid: Citrus terpene. This is a natural, quickly evaporating (and careful: easily inflamable) solution-aid produced from natural essential plant oils. It brings the solution. Since it is an extremely thin-fluid substance it will go deep into the wood and take the oil with it. The oil will remain as a thin cover once the terpene has evaporated.
Then the pores and small chambers and channels in the wood are open again and will let the oxygen in and do its job. Oxydation and resinification will start. The oil will reach cavaties deep inside the wood and make it hard as amber (wich is the best known resin). In the bore the oil and resin will result in proper draining of water - this will prevent the expansion of the wood due to sucked in water.
Time and patience are important factors, too, since resinification takes time. It can be speeded up by adding substances that will increase the surface or assist the drying. So a suitable mixture could be: linseed oil + hempoil (all cold pressed) + citrus terpene + quartz + patience. Frequent application of small quantities of this mixture will lead to a humidity resident wood, that has never been loaded by substances that could muffle resonance. After some time this will make the instrument produce a strong tone, rich in overtones. New wood will be - in contrast - rather sensitive and must be treated with care, it will take years until perfection. New instruments should therefore be oiled frequently.
How to oil
To apply oil you use an old, non-fuzzing cotton cloth, that you dip into the oil-mix and then pull through your instrument (preferably with an aluminium flute wiper). After 15 minutes you remove the excess oil that has not been sucked up by the wood. All cloth parts that had contact with the oil must be stored in a firesafe place (like a closed steel bucket). They are not poisonous, but they might selve-inflate.
I recommend to oil the bore of a relatively new instrument about every two to three months. Later, when the instrument gets older, you do it only once a year (like when you have it for a yearly overhaul). The outer surface can be rubbed just once a year, and again, remove the excess oil 15 minutes later. This will clean away the sticky crusts from skin fat and sweat as well. But make sure the oil does not sink into the tone holes or the holes for the mechanique because it will make these stick as well.
Painting
Off course many have tried to protect instruments by painting it with moisture-resistant paint. Where only the bore was treated (usually with some two-component- or resin-paint) the results were promising, even from an acoustical point of view. But unfortunately even the best paint does not stick on for ever. The humidity will go into the wood somewhere, especially at joints and in the tone holes, undermine the painted surface and this will result in mouldering and cracking of paint. The bore will then look like being gnawed at. That is not really what we'd like to see - a mirror-like surface.
If you find paint has been applied to the outside of an instrument, then this is almost always to cover up little faults in the wood. For economical reasons it is not always possible to use fault-free wood for inexpensive instruments. This just a note for completeness...
Should you now have any questions concerning the smell of the oil mix, be assured that this will smell rather of lemons and oranges - not everybody likes that, but most of us do. This could inspire your music, too, couldn't it?
Addendum:
If you want to produce the oil mix yourself, make sure to buy only small quantities (in the bio-food-shop), since the oil will age and then resinify quickly. The mix will be good for some months, if you keep it in a dark bottle, close tight. Once opened, you should use it up quickly. If you don't know for what - it will prove good for furniture or wooden floors, too!

The posts above correctly point out the necessity of swabbing and drying thoroughly. Oiling the bore is probably optional, but can't hurt if it is done sparingly and carefully.

Beyond that, the best preservative measure is to keep the clarinet in a good case at all times when it is not in use. Keep the case in a closet or other location where it will not be exposed to cold drafts, hot air blasts, damp conditions, etc.

I'm posting this hear because, in part, it's a contribution; but also I have a question...

Do people really clean the joint corks and (re)apply parafin wax on a regular basis?
around 4:16 on the video.

Anyway, I quite like this players channel, some of her videos have helped playing wise....

I didn't read all of Milandro's attached article but I'm sure it covered just about everything you would ever want to know about clarinet maintenance. One suggestion I would add to drying with a swab and occasionally running an oiled swab through it is to put it away in its case and leave the case open for a few hours if possible. This will give time for any moisture left after swabbing to evaporate. I believe my Buffet came with a small card in the case that recommended doing just that, so many years ago. I've had it since 1976 and it looks and plays like new because of the simple maintenance I just mentioned.

Milandro, I have a couple of concerns about the article: http://www.the-clarinets.net/english...tt-oiling.html

1. I used raw linseed oil on some elegant, manipulative timber puzzles etc I made. What a disappointment! It polymerised to a sticky state like half-set varnish, and is still like that, decades later, making the puzzles very unpleasant to handle, smelly, and some of them too sticky to operate. (BTW the same happened with tung oil.)

2. From how I see it, this article conflicts seriously with information and recommendation provided, mostly in the Clarinet BBoard forum, by Omar Henderson of Doctors Products. As a USA government research chemist chemist with access to extensive laboratory resources he did a lot of study of effects of different oils, and presented his findings, probably a bit technical for most.

For what it is worth, as a result he sells "Grenadoil". It is an identical copy of the oil originally in the mpingo timber that is used for clarinets. The main component is exactly synthesised and the rest is distilled from wood chips from a leading clarinet maker. I found the research he presented very, very convincing.
