Are you experiencing black mold on your shower caulk? There is nothing worse than mold in a shower stall, and mold spores are always present wherever there is moisture. So long as they have moisture and food to endure, their numbers will continue to grow quickly.
It is important to address the issue very early in order to prevent damage to the walls and caulking of your shower. You can remove black mold and prevent its recurrence by following these steps.
What causes mold growth on shower caulk
Whenever there is prolonged moisture, mold grows. For example, a poorly ventilated bathroom will have a 60 percent relative humidity level or more. This will result in the spores present in homes attaching to shower caulking and resulting in mold growth.
Mold also feed on materials like wood, soil, cloth, and paper, these materials that are often found in bathrooms.
How to Get Rid of Mold in Shower Caulk?
Step 1: Get your supplies

Step 2: Add ventilation
Chemicals such as bleach can burn your lungs and cause breathing problems. Ensure you work in a well-ventilated room. Open all windows and doors and put on the mask and gloves.
Step 3: Apply bleach and wait for it to dry
Pour bleach onto the caulk that has the mold over it. Place toilet paper onto the caulk. This will help to set the bleach so that it does not evaporate away. Wait 12 hours minimum but overnight is best if you don’t need to use the shower.
Step 4: Pull off the toilet paper and observe
It is important to remove the paper after the specified time has passed. Check and see if the mold is gone. If not, follow on with the vinegar.
Step 5: Now for the vinegar
The next step involves vinegar – your friend but mold’s worst enemy! Simply spray vinegar on the moldy area to get effective results. Let it sit for about two hours. Follow up with a warm water rinse.

Step 7: Replace or re-caulk the caulk
If you find the combination of cleaners doesn’t work, you might need to replace the caulk.
