How to clean a moldy rug

  • Scrub the areas with a brush
  • Leave it for half an hour
  • Then rinse it with water
  • Finally, hang it somewhere to allow it to dry in direct sunlight.

White Vinegar and Dish Soap

White vinegar and dish soap can both be used to get rid of green mold from carpet.

  • Just mix them together and apply the solution to the stains.
  • Allow the rug to soak for 30-50 minutes
  • Rhen rinse it off and completely dry it.


Bleach is also an option that will instantly get rid of any mold you may have (green or white), but this approach is toxic, especially if you have kids or pets.

Bleach is very effective, but will also makes the rug’s color fade away. It’s better to use it on white rugs.
