recaulking bathtub

Quite often, a cheap, plastic scraper will work well without scratching your tub. Sometimes, you have to get down with a razor blade....... Sometimes, just rubbing it hard with your fingertip will work.... Once it's gone... go over it with denatured alcohol to clean it up... Let it dry thoroughly before reapplying new caulk.
Before you recaulk.. fill the tub with water - it will actually settle a bit making the gap a bit larger. Caulking compresses well but doesn't stretch worth a darn.... so you want the gap as big as it's going to get before applying caulk.
Pure silicone caulking is "best" but hard to work with... Latex caulks work well, but don't last quite as long nor stretch/compress as much. Either way... tape off where you don't want caulk..... apply a thin bead... smooth it with a wet finger - don't overwork it............ and remove the tape promptly. Hopefully - you'll have a nice waterproof seam.
