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.

Is it safe over solar panels?

Asked by Cathy February 7, 2021
1
Answer

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.

Asked by Kent January 30, 2021

Answer

Kent - Spray and Forget Super Concentrated Roof Cleaner is a non-corrosive alternative to those expensive pressure washers. For initial stain removal you want to use a 5:1 concentration, which would be 21 oz. of Spray & Forget to each gallon of water. For preventative maintenance you want to use a 9:1 concentration, which would be 13 oz. of Spray & Forget for each gallon of water. Uses no bleach, lye, acid, phosphates or heavy metals. It comes with a sprayer capable of spraying up to 20 ft. Each 32 oz. bottle will clean up to 600 sq. ft. (Non-Refillable)

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.

Can this product be used via a Pressure washer?

Asked by pistol77 December 30, 2020
2
Answers

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.

Removes stains. Does not remove moss.
I bought this exact product from Home Depot in June of 2019 to remove bright green moss growth on the north side of my roof, mostly because the before and after pictures on the product label attached to the bottle clearly show that's what it's for. And, within 48 hours of application, the moss turned brown. Great! Unfortunately, that's all that happened. Nine months later, Feb. 2020, that ugly brown growth is still attached to my shingles, as firmly as ever. Now, I'm thinking that I'll have to power wash it off, which is what I should have done in the first place! This product does remove mildew stain (that I didn't even realize was there), but it does NOT remove moss growth. The before and after pictures attached to the product label clearly indicate that it should, but as my own pictures show, that's not been my experience.

Used as directed on a problem the product indicated it treated. In fact one week later I applied a second treatment. Again, failure. Eventually I called a company that specialized in cleaning roofs. The company did the job that Spray & Forget couldn't and did an amazingly good job. I received lots of compliments from my neighbors. The house was up for sale and I needed the roof to look good. I was disappointed that this product couldn't even remove simple moss after two applications applied as directed.

It works as advertised
Very easy to use. Just spray and forget! When applied it appears that you wasted your money, but you have to be patient. Depending on the extent of the contamination it can take 6 months or more to see results, but I am very pleased. Heavy black and green mold and mildew has slowly faded away and the surfaces (concrete slab, plastered walls, brick wall) are nearly clean. I think I will give it a buster shot and that should take care of it. I also used it on my gravel parking area, where I had some slime forming. I had tried many herbicides and everything I could think of, including a flame thrower - nothing worked. The flame thrower worked only temporarily. But a single application of Spray and Forget did a wonderful job. I applied the spray when the slime was dry, that way it would absorb the spray like a sponge rather than just run off the surface.
