Spray & Forget1-Gallon Concentrated Roof Cleaner

Took 3 times of treatment but very effective.

left a bad review on this product found a video online how to use it states takes 3 to 6 months to work, not what the dscription states! works in minutes, another vauge advertizement on Amazon, no man in his right mind would purchase a product that promised to work in 3 to 6 months? no way, put that in bold letters on your add people, I get a letter from HOA I have one month to comply, waste of money, I will follow up 6 months from now if it works then, already ran through one gallon on two small sections of my roof, 10% help is all, [followup 10-10-23 my roof still isn't "perfect" as the add states, bought in July, other products I have to get on top of the roof and have but at 70 yo don't need to do that, I used the spray bottle attachment, I have sprayed one side twice, had a company spray and it still isn't "nice" I have no choice but to use this due to age and mobility, I just have to do multiple appications, ADD still states works in minutes not weeks, that is a total lie, my roof wasn't as bad as the ones in the video but after watching the video of how to use it and then it stating takes 3 to 6 months to work, I purchased 2 gallons and the concentrate sprayer and used all of it and the roof still isn't nice, if ur old like me and can't climb on your roof to use a real bleach product, this seems to be the option, gonna buy another batch and hope for the best] makes me mad the advertisements that lures inocent people to buy lousy products, that is what the USA has become, steal and lie to everybody to get the numbers on paper to looks good, no respect for others, just rip them off, just numbers in a bank account is what many/most americans look for, sad, look around you now just sad

I had a shed with heavy algae growing on it. I sprayed this on and let the rain take it off. I still had thick parts which I had to use a pressure washer to, but it loosened up so I could remove it.

Spray this product onto your vinyl siding, let it sit for a minute brush it down with a soft car wash brush or something else, and then hose off. This is an amazing product that keeps your house clean very quickly without scrubbing. It's very easy to use as well

Three years ago I spent 4 hours power washing the green growth on the North side of my 2 story home. Three weeks later it returned. I purchased a good 2 gallon sprayer and applied the Spray & Forget in 20 minutes ; without the need to use an extension ladder. Within 3 hours the green was gone; with only a light gray haze remaining. Subsequent rains removed the gray haze. It lasted 3 years until I reapplied it this week. The green faded in 3 hours. It is a fantastic product for vinyl siding. It did not work well on asphalt shingles or heavy growth on the patio hardscape. A 5 Star product for asphalt shingles is Wet & Forget. It removed the black mold on my roof is 5-6 hours and has lasted 3 years. I have to reapply it to 1 of the 8 sections of my roof.

Mixed product as instructed, it does not work as well as described, had to treat twice and use pressure washer.

would recommend it.

Does not work try a different product or pressure wash
