It is my personal experience that "a kissing sound" always means romance is in the air. History bears this out. That kissing noise many decades ago resulted in heated passions on a young saxophone, and TA DA, the result after 9 months of this noise was the birth of the high F sharp key. This has also occurred on the soprano sax with the birth of the high G key. Left untreated, these hormones will rage throughout your instrument, and soon we will be having the birth of new keys on the neck of the saxophone. As the wise deputy sheriff, Barney Fife said: "Andy, we gotta nip this in the bud." Of course Barney was correct, so be alert of these romantic goings on, and kissing noises, especially when your saxophone is in a dark case, and left to its own devices.I wouldn’t be happy with a kissing noise either. I’ve been subbing with the community band the past 5-6 weeks and the guy I sit six feet away from on my left at practice is constantly dealing with a sticky G# and bis Bb (folded bills) and he has this “kissing” noise you speak of. He also swabs and uses a pad saver at the end. The other three sax players don’t seem to have much issue with theirs, at least not at rehearsal.
The deal with pad savers is getting one that doesn’t shed fibers. The fibers that come loose can stick to the pads or tone holes/ rims and cause slight leaks. If the sponge isn’t the right thing for you, maybe kitchen paper (paper towel?) as JimD mentioned would be more useful. Again just make sure to grab a brand that doesn’t shed fibers...you’d actually be leaving excess moisture behind if you used a brand that leaves particles behind. I clean airbnb properties since gigs went away and there’s some brands of paper towels that leave a lot of fibers behind...I hate having to wash windows and mirrors twice 🤣
