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.

    If it's silicone caulk, acetone doesn't actually do much to it. Acrylic caulk is another matter. It's still good for post-removal cleaning unless the substrate is attacked. – Chris H Aug 14 '16 at 13:05

    I just found the caulk I used. It was silicone – Matt Aug 14 '16 at 13:06

    Carefully with a single edge razor blade is about as good as you are going to get it. – Jack Aug 14 '16 at 15:44
