A few years ago we redid the tile in our master bathroom shower. At first, it looked great, but after some time the caulk has started to get some mold on it.

I didn’t really feel like removing all the caulk so instead, I decided to go through and clean the moldy caulk.

It’s a pretty easy process to remove mold from your shower caulk. It just takes a few things you probably already have around the house and about an hour of your time. If you want to get rid of the mold check out this easy tip on how to remove mold from the caulk.

How To Remove Mold From Caulk

To remove the mold in caulk in shower you will need a few things listed below. You probably already have them at home.

  • An old toothbrush or small brush
  • a disposable cup,
  •  Baking Soda
  •  Bleach

If you don’t have a disposable cup you can also use a cup that you can throw out after you are done. You probably don’t want to use a cup after the bleach mix has set in it.

You also may want rubber gloves to wear on your hands and a face mask to help with smells depending on how bleach affects you.

You will also need about an hour to let the bleach mix set up on the mold.

Getting Started

Mix about 1/2 cup of bleach with about a cup of baking soda in a disposable cup.

You may want to do just a little at a time of each. The amounts you will need will vary based on what kind of bleach you use.

You will want to get your mix to the consistency of toothpaste so it will stick to the moldy caulk.

Applying the Cleaner To Moldy 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.
