GREAT PRODUCT

If you have screens that are green (Florida) , this works ! We are in a drought area and can't pressure wash right now . I used this product and it cleared up the green. Helpful hint , I put it in a pressure sprayer instead of the Hand sprayer that it comes with . For big areas it's much easier .

Great product, great price, great service.

This product if the best for removing lichen (fungus) from gravestones. Effective and easy to use. The Walmart price was great. I never left my recliner to order the product. I never left my car to pick the product up the next day.
