  • Distilled white vinegar

  2. Grab the paint brush and use it to apply the paste to the mold.
  3. Use the plastic wrap to cover the paste on the mold as best you can. This can be tricky. Feel free to tape it.
  4. Leave it to sit for at least 2 hours.
  5. Remove the plastic covering and clean off the paste which most likely will have dried out.
  6. Repeat this process until you are no longer seeing a reduction in the amount of mold on the shower caulking.
