  • Removes mold and mildew stains within seconds
  • Removes mildew and mold with no scrubbing needed
  • Safe on all surfaces
  • Super concentrated formula
  • No rinsing required leaving surfaces cleaner and spot free.


  • Very strong ammonia smell although this passes quickly
  • Results may vary based on severity of mold and mildew buildup

Our pick for removing mold and mildew stains is a ready-to-use spray that rubs off the stains. It also works as a general mold and mildew spotter.

The secret weapon of this stain remover is actually one of its components and that is mycotoxin-degrading enzymes. This allows it to penetrate deep into the stain and break down the mycotoxins that remain even after a thorough cleaning. It's a chemical-free, all-natural solution, but also very powerful.

It also has an anticalculus and anti-mildew formula that kills mold and mildew spores. It's just not safe to use on certain products, but generally for most other surfaces you should be fine.

The only drawback is that it's formulated for hard surfaces while mold has a tendency to grow in corner and underneath furniture and showers, which is why you need to either spray it from a can in a larger area, or put the spray in a large spray bottle with a pump.
