If you have a dirty bathroom surface that you can’t get clean no matter how much you scrub, you’re probably not dealing with dirt but a tiny fungus called mildew. Well, this is what you can use right here. Hydrogen peroxide is an agent that oxidizes just like bleach, but much safer. Hydrogen peroxide will kill mildew on contact.

The chemical makeup of water is H2O, but hydrogen peroxide is H2O2. That basically means that as it works, it oxidizes, leaving only water behind as a byproduct.

Begin by mixing one cup of hydrogen peroxide with a gallon of hot water, and then you can go ahead and transfer that to a spray bottle and spray that directly onto your grout joints where you see the mildew. I’m going to let that set up for a couple of minutes. Then you can go ahead and agitate it with a brush.

Now I’m going to apply some more and let it stand for about 15 minutes. That looks pretty good. But if you have some residual, you can also try using undiluted hydrogen peroxide straight onto the tile. Then go ahead and agitate with a brush as well.

So that’s it. If you have some mildew stains that won’t come out, try some hydrogen peroxide.
