1 Gal. Revolutionary Roof Cleaner Concentrate

Dear Valued Home Depot Customer, We have reached out to the manufacturer and their answer is, I am writing you in response to the question that you posted on www.homedepot.com asking can this 1 gallon container be used to refill the hose spray bottle? I have a rather large, steep roof and I can only reach certain spots on a ladder and relying on the hose spray bottle to reach most of my roof. A garden sprayer is impractical to use on. The hose-end product is non-refillable. Also, the 1 gallon concentrate product is a different formulation and less concentrated than the hose-end product. You would not get the right concentration of product to achieve optimal performance. As the manufacturer, we are very interested in supplying consumers with the best quality product that delivers the expected performance.We pride ourselves on customer service and we consider our customers our first and highest priority. Thank you for being a valued customer and we appreciate your business.

Only for roof use.

Cathy - Spray and Forget Roof Cleaner Concentrate works to remove green and black biological stains caused by algae, mold, mildew, lichen and moss growths and is safe on almost any exterior surface. This product does not contain any harmful agents like chlorine or bleach and is not caustic like Sodium Hydroxide. It is a proprietary blend of surfactants, which is basically a blend of soaps. However, because there are many types and grades of building materials on the market we always recommend testing a small are first to be safe. Avoid spraying the product on glass or directly on the solar panel or lightly wet before and after product application to avoid any clear film residue. We also recommend that you check with the solar panel manufacturer before applying any product like Rain X to keep Spray and Forget or any other products from adhering to the solar panels and see what other suggestions they have.

John-Spray & Forget 1 Gal.

It does not contain any harmful bleaching agents, like chlorine or bleach, and is not caustic like sodium hydroxide or corrosive chemicals. Product is toxic to marine life. Do not use the product within 25’ of any public water and do not dump the product into city sewers of public waters. Keep pets away until surface is completely dry.

Probably not - my washer's "low pressure" soap application feature mixes in the soap at a 1:20 ratio. The instructions say this cleaner requires between 1:5 and 1:9 depending on the nature of what you're cleaning. Check your washer's manual, but in my case it would be far too diluted. And in case anyone was thinking it, one should never use any *pressure* from a pressure washer against a shingled roof. It will likely cause significant damage to the shingles.
