Mold or Mildew? | How to Remove Mold From Caulk
Mold is a four-letter word, and it’s a headache!
The bleach test
Take a cotton ball soaked in fresh household chlorine bleach to the mildewed caulk. If the mildew disappears immediately, you’ll know it’s growing on top of the caulk. A good shower cleaning is in order.
If the mildew disappears but takes 45 seconds or longer, it’s likely mildew under the caulk. Fixing that takes more work (and gumption). Here’s how to tackle that project.
1. Remove the caulk
2. Assess the situation
Is there mildew visible where you removed the caulk?
3. Eliminate the mildew
Hopefully, the mildew growth is localized and minor. A mildew remover product or a mild household bleach and water solution – 5 parts water to 1 part bleach – will do the trick. If that removed tile hints at anything more serious (like mildew covering the wall and/or the back of the tile, or visible mildew around surrounding tiles, etc.), time to call in a specialist.
4. Re-set the tile and seal the grout
Prevent any future moisture infiltration through that grout. Seal it up! Your local hardware store will have grout sealer. Re-caulk after all of the mildew is removed and the surface is clean.
6. Enjoy your hard work.
Have an iced tea. Or a latte. Or some ice cream. And enjoy having more free time. (Time is the best, really.) Most importantly, enjoy that first mold-free shower. Linger a while longer under the hot water while you stare at the lack of ugly black stuff. Soothing, isn’t it?
