How do I remove mold on bathroom caulking?

Hydrogen peroxide left on to soak can work pretty well. An oxyclean paste is also another option. Good luck!

Here's a link with a few ideas:

Bleach on cotton balls leave on over night

Soak cotton balls, paper towels, or old rags with white cleaning vinegar. Place on caulk and let sit. Remove and rinse well. Bleach will remove the appearance of mold but doesn't kill the spores but vinegar will. If there is any staining, you may need a bleach product to remove that after killing the mold.

Sorry but I tried this using bunched up toilet paper. No difference

White vinegar or cleaning vinegar. Will kill the mold spores. Bleach does not.

Hi Donna, hope this helps you out,

To remove mold from caulk, start by spraying the caulk with 3 percent hydrogen peroxide and letting it sit for 10 minutes. Then, scrub the caulk with a sponge and wipe the area clean. You can also try spraying the caulk with white vinegar and letting it sit for an hour before rinsing the vinegar off.

Vinegar kills mold.
