  • Patience Is the Point - SRW M3C Mold, Moss and Mildew Cleaner Sample, 8 oz

    Patience Is the Point

    M3C is not a pressure washer in a bottle. You apply it and walk away, and it breaks mold, moss, mildew, lichen and algae down at the root over days rather than minutes.

  • Safe Across More Than Hardscape - SRW M3C Mold, Moss and Mildew Cleaner Sample, 8 oz

    Safe Across More Than Hardscape

    Because M3C is non acidic and bleach free, SRW lists it as safe well beyond the patio, which makes it the one bottle for the whole shaded side of a property.

What You Get

One 8 ounce bottle of SRW M3C, drawn from a factory sealed container and filled here at our New Jersey warehouse.

  • 8 ounce sample bottle with a sealed cap, clearly labeled
  • The same formula as the quart and gallon, no bleach and no acid
  • Enough for a small test area on the shady side of a property

Patience Is the Point

M3C is not a pressure washer in a bottle. You apply it and walk away, and it breaks mold, moss, mildew, lichen and algae down at the root over days rather than minutes. There is no scrubbing and no rinsing.

That is exactly why a sample is useful here. It lets you see the timeline on your own surface, in your own conditions, so you know what to expect before you treat a whole north facing walkway. If you are expecting an instant result, the sample will reset that expectation cheaply.

How to Use the Sample

  • Pick a small area with visible moss or algae growth
  • Apply per the SRW label and leave it alone
  • Do not scrub and do not rinse, the product needs to stay in contact
  • Check back over the following days as the growth breaks down
  • Rain is fine, it does not wash the treatment away immediately

Safe Across More Than Hardscape

Because M3C is non acidic and bleach free, SRW lists it as safe well beyond the patio, which makes it the one bottle for the whole shaded side of a property.

  • Concrete and clay pavers, natural stone
  • Block and segmental retaining walls
  • Roof shingles
  • Asphalt driveways
  • Wood decks and fencing

Ready for the Full Size?

Once the sample shows you the timeline, the full SRW M3C, 1 quart and 1 gallon is here. Browse every paver and stone cleaner we carry, or the rest of our sample bottles and color kits.
