How To Remove Caulk

We’ll show you in just a few easy steps how to remove caulk so you can prepare your project for fresh new caulk. Caulk can sometimes be difficult to remove, especially modern silicone caulk products that are simply designed to not come off.

#1) If the caulk on your project is shrunken and loose and easy to pull off, buy all means go ahead and remove the loose caulking by hand. Usually, however, it just isn’t that easy.
#2) The most important step in removing caulk easily is to apply a caulk remover product such as McKanica Silicone Caulk Remover Gel or 3M Caulk Remover.  These products are designed to soften and/or desolve silicone and other adhesives and caulk so that they can be removed.
#3)  Cut the softened caulk by using a sharp utility knife, or use a caulk remover tool.  In many cases most of the caulk will now come out easily.  If there happens to be several layers of caulking or if the caulk is very thick or a strong silicone caulk, you might need to use other tools to scrape and remove the caulk.
#4)  The last step is to clean your project surface and remove any residue or mildew.   Using one of the above-mentioned caulk removing products should help remove any silicone or adhesive residue.  Use an ammonia-free bathroom cleaner to remove soap scum.  Never use an ammoniated household cleaner before applying bleach!  When ammonia and bleach are mixed together, they give off poisonous fumes.  After soap scum is gone, use a bleach and water mixture several times, working into the gaps to ensure that all mold is killed.  Then simply dry the surface with a clean rag.
#5)  Your project is ready for new caulk!  There are wide variety of excellent caulking products available.  For bathtubs, a silicone caulk which contains fungicide is ideal, such as Dap 18526 Kwik Seal Plus Kitchen and Bath All-Purpose Adhesive Caulk.  You’ll find a variety of silicone caulking products at
