Remove Old Bathroom Caulk in 4 Easy Steps

Bathroom caulk is very important. It is a moisture barrier and keeps the water from seeping in between your bathroom fixtures and the walls. It’s the ideal spot for mold and rot to form, causing huge problems down the road. If your old caulk is peeling or cracking, now is the time to perform a small replacement job to keep your bathroom safe.

Soften the Old Caulk

Removing the caulk “as is” will cause leftover residue and pieces left behind. Instead, use a little caulk remover to get the job done. Apply to the layer of caulk and then let it sit for at least two hours. For better results, leave it alone for 24 hours.

Use a Tool

Caulk remover tools are available at the hardware store. While you can use a knife, it can also cause damage to your walls and to the surface of your tub. Instead, spend a couple of dollars to purchase the tool made specifically for the job and use it to remove the softened old caulk around your tub, shower, or sink.

Clean the Mess

Caulk removal makes a mess. There is just no way around it. Sometimes it comes off in long strips which are easier to dispose of, and sometimes it comes off in a million pieces. After removal, clean up the area so that the old caulk does not mix with the new caulk during application. Dispose of old caulk according to local guidelines. Use a toothbrush to remove any remaining debris of residue from the surface.

Sterilize the Seam

Before applying the new caulk, sterilize the surface. Clean with rubbing alcohol and then use a bleach solution to sterilize the surfaces. This kills any mold or bacteria that may have been growing underneath the old caulk, preventing the spread once you apply the new caulk.

Once the old caulk is gone and the surface sterilized, you have a clean slate to apply a new layer of caulk. It is important to keep the surface dry until you apply the new caulk to keep out all the moisture. If you are looking for help with your faucets or bathroom fixtures, Mr. Rooter can help.
