BestSaxophoneWebsiteEver.com recommends Spit Sponge and GapCap
"[Spit Sponge] is a great product for keeping your pads dry as well as tone-holes clean to further prevent your pads from sticking."
"The GapCap is a great solution for those players who like their current saxophone case but have realized that their saxophone or case is not a perfect fit. The GapCap will prevent your saxophone from moving around in the case, which many times is where damage will occur. In addition, if you ever switch horns or purchase another saxophone, the GapCap will assist with making your new saxophone a more secure fit."
