How To Remove Black Mold From Shower Caulk

Mold in the bathroom is a very common thing that a lot of us battle, and it’s so gross!

Mold LOVEs warm and moist environments, so after a hot shower or bath, it’s essential to dry out your bathroom so that the mold has a harder time to get growing.

Unfortunately, a lot of us in older homes (like me!) don’t have a ventilation system in the bathroom, and that makes drying out the room a lot more difficult after taking a hot shower or bath.

If you have a window, make sure to keep it open so that the moisture dries up quickly. 

The only problem is, if you live in a winter wonderland, having the window open after a hot shower isn’t an option. 

Then you must take extra steps to make sure your tub dries up.

But those of us with kids and busy lives don’t take the time to make sure to dry out tubs, and the mold loves that!

Alternative Methods I’ve Tried

These are also excellent methods, but in MY opinion, they didn’t work quite as well as the bleach solution. I PREFER to use no chemicals in the house, but sometimes, when it comes to mold and health, bleach is my go-to.

I’m well aware of the benefits of tea tree oil and its disinfecting properties, but come on…bleach is just much more durable, and so I trust it more in these situations.

However, if you don’t have bleach in your home, or you prefer to use natural products, there are some other things you can do to get the mold off.

Baking Soda Paste Solution

Just so you are aware, baking soda does NOT kill mold, but it can help remove any excess moisture from the caulking which helps prevent mold growth.

Create a paste with your baking soda and some water and apply it to the caulking.

Leave this paste on the caulking for 20 minutes or so.

After the 20 minutes has elapsed, go ahead and scrub away at the mold with a toothbrush or soft brush.

Hydrogen Peroxide

You can use straight hydrogen peroxide applied to the moldy caulking in your tub or shower.

Use a spray bottle to apply the peroxide and let it sit for 10 minutes or so before scrubbing it with a soft brush or toothbrush.

Make sure to dry the area when you are done!
