What Customers Are Saying
The product appears to have mixed results. Many customers report it is an effective and easy-to-use solution for removing mold, mildew, and algae from outdoor surfaces. However, some found it did not work as well, especially on tougher stains or larger areas. The product seems to work best for lighter growth, but may require additional scrubbing or treatments for more stubborn issues. Customers note it can take several weeks to fully work, so patience is required. Overall, the consensus is the product is useful, but its effectiveness can vary depending on the cleaning needs.

Would RecommendActually the jury is still out in this product. Instructions say it could take months for mold to disappear. We can tell a difference after 3 weeks.
