How to Remove Caulk from a Bathtub
Caulking is a flexible sealant that keeps water from leaking into the walls behind a bathtub. Applying caulk to the void space between the tub and wall creates a watertight seal. Over time, and through use, caulk shrinks, pulls away from the seams and degrades, rendering it useless. Parching, broken or missing caulk requires removal and replacement to keep a bathroom protected from water damage. Moisture can cause mold, mildew and wood rot that threatens the structural integrity of the bathroom and house. Remove and replace caulk as soon as it shows signs of failure. Does this Spark an idea?
Things You'll Need
- Needle-nosed pliers
- Caulk remover
- Plastic mesh scouring pad or plastic scraper
Instructions

1
Pull old, loose caulk out of gaps and seams with your fingers. Use needle-nosed pliers in areas that are hard to reach.
-
2
Apply a coat of caulk remover to the remaining caulk. Caulk remover softens the caulking and breaks the bond between the tub and wall surface. Many commercially prepared caulking removers are safe for use on any surface. Always read the manufacturer's recommendations before applying.

Allow the remover to remain on the caulking until it is soft and pliable, typically 20 to 30 minutes.
-
4
Scrape the remaining caulking material away from the tub with a plastic mesh scouring pad or plastic scraper. Do not use steel wool or metal scrapers, as these will likely scratch the surface.

Tips & Warnings
Wash the area to remove caulking remover from the surface before reapplying it. Use care when washing to prevent water from entering the exposed areas.
Do not bathe or shower until you apply new caulk to the gaps and seams.

Although they now require sharpening, I removed caulk in my tub using my sharp wood carving gouges. They come in many useful shapes for removing material (U-shapes with narrow blades, flat sharp blades) and they can be driven with a mallet to ease out the old caulk and grout. I highly recommend wearing gloves and kneepads when doing this, and keeping your drain pugged to avoid having removed material block the pipes. If possible, consult a knowledged plumber before even attempting this project.
