I have read in several places, including here, that using acetone as part of a caulking clean step is useful/effective. I have scrapped off most of the caulk on my bath tub and am trying to clean the residual using some acetone and a brush. However I feel like the acetone (100% according to the bottle) is not actually doing anything. I can't just let it sit there as it evaporates rather quickly.
Are there any logical reason I should not be using acetone to be cleaning up caulk? Is there perhaps a better alternative for residual caulk removal.
