Want to know how to get rid of moldy caulking in your shower? Use the following cleaning tip to remove black mold from caulk around your tub.

Everyone knows mold is gross. Unhealthy. Bad for you. Yet, it’s in pretty much every home, especially in areas where there is moisture naturally, like in your bathroom!

We have mold growing in our bathroom, along our bathtub, in the caulking that’s there. As we live in an apartment, it’s not exactly up to us to remove and replace the moldy caulking, though that would be the ideal way to deal with the situation – remove the caulking and reapply new caulking around our tub, addressing any underlying issues that may be there.

If you own your home, that is the best route to go. But, if you want a “quick fix” or something that is more affordable then new caulking, and likely far less time consuming, and don’t want to wait two days for the new silicon caulking to drive, the following is cleaning tip that works really, really well.

6. Continue adding more cotton balls or cotton coils to all moldy caulk in your shower, including along window ledges, and up the walls. Because the cotton is so wet, it will stick vertically. However, start at the top and work your way down if bleaching moldy caulking vertically, as the liquid will seep out and make the cotton balls below it fall off.  It’s okay to keep the cotton fairly wet, but it doesn’t have to be super wet and drenched, especially if doing vertical parts.How to Get Rid of Mold in Caulking - Remove Mold in Bathroom bathtub caulk

If using cotton balls, you can stretch out the cotton balls before dipping them in the bleach water to make it easier to attach to a wall.

7. Leave the cotton there for about 2-4 hours or until mold is removed. Be sure to shut the bathroom door and keep the fan running as you wait.

8. Spot check an area to see if the mold on shower caulking is gone. If not, reapply and wait another hour.

9. If the spot check looks good, continue to remove the cotton balls or cotton coils from your bathtub caulking, discarding them into a trash bag. Always be sure to handle bleach with gloves on and a mask if you have one (and glasses if you are worried about splashing or spills).

10. Let air dry. You don’t need to rinse with water, though I found it helped make the smell go away faster.

*If it doesn’t work, check the date of your bleach. Bleach has a fairly short shelf-life. If you haven’t used your bleach in five years, or your bottle doesn’t smell very strongly like bleach, get a new bottle and try this again.

An important note about using bleach to remove mold

Mold is no longer considered to be the best way to remove mold. It is only effective if the mold is on a non-porous material like tile, bathtubs, glass, and countertops. It doesn’t reach the mold growing underneath the surface. Also, bleach can damage the materials it is used on as it’s a harsh, corrosive chemical. The fumes are strong and harsh and it must be handled with gloves.

Also, you should NEVER mix bleach with ammonia.

However, the bleach does do a great job at removing mold usually and also removes any mold stains as well, which is why I used it in my bathroom. I usually prefer less harsh chemicals or natural cleaning agents, but I am also a fan of using something that works, the first time.

Other alternatives to using bleach to remove mold from caulking would be:

I, however, have not been able to find many tutorials on how to use these products specifically for cleaning moldy caulking in bathrooms, so if anyone has tried using them, with success, I’d love to know! I tried making a paste of water and OxiClean and slathered it onto the moldy caulking, but it did absolutely nothing. It dried out shortly after application and didn’t remove the stains at all.

If you know how to remove mold from caulking without using bleach, I’d love to know!

In the meantime, bleach totally works to get rid of mold on shower caulking! Just be careful handling it. Enjoy a whiter bathroom!

    For mold in the caulking of my tubs, I use a gel toilet bowl cleaner that contains bleach. I squirt it on and let sit for an hour or so. I then get an old toothbrush and scrub a little, then rinse. Because it is a gel it stays on very well.
