How To Remove Mold From Caulk

Once you have it mixed to a thick paste then use the old toothbrush to apply it to the caulk that is moldy(You will probably want to spot test in on a small area first to make sure it doesn’t damage the tile).

Make sure it is thick enough to fully coat the caulk. Set a timer for about 30 minutes and then just let it sit.

It smells really strong so you may want to turn on a vent in the bathroom or open a window to help with the fumes.

After 30 minutes check on the bleach mixture and make sure that it is still fully covering the caulk.

Add some more bleach mixture to the caulk if needed. Then set a timer for about another 30 minutes.

Removing the Bleach Mix

Once the bleach mix has set over an hour then you can use the toothbrush to scrub the caulk for a minute or two. Then use warm water to wash away the bleach mixture.

Make sure you rinse all of the bleach mixture off of the caulk and fully washed down the drain. You don’t want to leave chemicals where you shower.

If you still see some mold on the caulk you can repeat the steps a second time to get rid of everything.

You can see how just one time of using this bleach mixture made a huge difference on my shower.

Preventing Black Mold & Mildew In the Shower

I get asked all the time what you can do to prevent the black mold or mildew from growing on the caulk.

One simple thing you can do is help prevent the moisture in the shower. When you finish in the shower leave the door or curtain open for a few minutes and run the bathroom fan.

This will help the moisture evaporate quickly to prevent mold.

Another easy tip is you can spray down the shower with a little bit of vinegar. This will help prevent mildew from building up on the shower caulk.

Unfortunately, vinegar doesn’t work as well as bleach on black mold.

Another great way to keep the mold from growing on the shower caulk is by using a daily shower spray.

With just these few easy steps on how to remove mold from caulk, you can get the moldy caulk looking like new again. Not only will the bleach mix remove mold spores but it also can remove some stains from caulk.
