Chemical Caulk Remover
An easy way to start the old caulk removal process is to use a caulk removal solution like that made by 3M. The remover destroys the bond between the old caulk and the tile, tub or sink. 3M's liquid caulk remover comes in a plastic squeeze bottle, costs less than $10 and removes a little over 20 linear feet of old caulk. This is a great way to get a jump softening up and removing the old caulk as opposed to only relying upon manually scraping the old caulk.
To use this remover simply proceed as follows:
- Squeeze remover onto the old caulk making sure to cover the old caulk completely;
- Let set for 2-7 hours as directed;
- Using a plastic putty knife or a caulk removing tool (see next page), scrape the old caulking away. It will come off in chunks;
- Clean up with soap and water.
