- Apply the Chemical Caulk Remover and Let Sit. Squeeze chemical remover onto the old caulk bead, so the caulk is covered completely.
- Scrape Away the Caulk. Use a plastic putty knife or other tools to scrape away the old caulk.
- Clean the Surfaces.
How do you soften hard caulk?For water-based acrylic caulks and caulks containing polyvinyl acetate resins, soak old towels with isopropyl rubbing alcohol and place them directly over the caulk. The alcohol makes the molecules in the caulk swell so it gets soft and easier to remove.
Does WD-40 remove caulk?
WD-40 is very good at removing silicone sealant, but just completely remove it from the surface before applying any new silicone sealant as they can react.
Does vinegar remove caulk?
Vinegar makes an excellent cleaning product and can even tackle tough projects such as old or residual caulk. The acid in vinegar helps break down hard, sticky or old caulk and dissolves it so it can be effectively scrubbed away.
What will dissolve caulking?
Vinegar and isopropyl alcohol will also do this. The best way to remove silicone caulk short of using a digestant is to treat it with a silicone sealant remover, WD-40, vinegar or alcohol, wait for it to soften and then attack it with a knife or paint scraper.
Apply A Softening Agent
There are several substances you can use to soften the silicone caulking. Among the easiest and most affordable are vinegar, alcohol, and WD-40. If you need something stronger, you can use industrial-grade isopropyl alcohol, and we recommend contacting a professional.
Soften the caulk with chemicals or heat.
- Commercial caulk remover is the simplest choice and may be your best option for silicone caulk.
- If you are dealing with non-acrylic water-based caulk, you can soak the caulk with saturated rags for 72 hours to soften the caulk effectively.
You can use either a small cup of vinegar or a paste of 1-part water to 1-part baking soda. Applied either of these to the caulking with an old toothbrush and scrub vigorously.
You can use a utility knife or putty knife, slicing through the caulk and peeling it away. For multiple layers of caulk, needle-nosed pliers might work best. There are also specialized caulk removal tools designed to tear away caulk cleanly.

Consequently, white vinegar is another solvent you can use to soften it. It may not work as well as mineral spirits or alcohol, but it poses little danger to the substrate to which the caulk adheres. Rubbing a tabletop exposed to silicone wax with vinegar may safely remove some of the silicone.
The best way to remove silicone caulk short of using a digestant is to treat it with a silicone sealant remover, WD-40, vinegar or alcohol, wait for it to soften and then attack it with a knife or paint scraper.
Scrape off as much of the residue as possible with a razor blade or flat head screwdriver without scratching the surface you are cleaning. Apply mineral spirits or denatured alcohol. Use a scrub pad if possible, unless the surface is easily scratched, then use a sponge. Scrub vigorously.
Once silicone caulk or silicone sealant has cured, there is no single silicone remover that will easily remove it. White vinegar can remove residue after silicone has been scraped off.
- Soften the caulk by applying caulk remover.
- Slice through the softened caulk using a utility knife with a fresh blade or a caulk scraper.
- On the other hand, if there are several layers or if the caulk is very thick, you may need to pull the material from the joint with a pair of needle-nose pliers.
WD-40 is very good at removing silicone sealant but just make sure to completely remove it from the surface before applying any new silicone sealant as they can react. All you need for cleaning up the WD-40 is a clean dry cloth and mineral spirit.
