Rated 4.2 out of 5 by 16 reviewers.
Rated 4 out of 5 by Worked as advertised Applied it on my deck through my power washer on low spray level. Used a stiff brush with light pressure to work it in a little better. Let sit for about 10-15 minutes, making sure it didn't dry by lightly spraying every 5 minutes, and power washed it off at medium to high pressure. Deck wood looks almost new. Removed all the mildew, dirt, and grease spillage from my BBQ grill. Deck is about 15 yrs. old and hadn't been cleaned in 3-4 years. Even loosened up the old peeling stain to help removal with power washer. Good product...worked as advertised. June 26, 2014
Rated 5 out of 5 by GREAT Tree Sap Remover I went over to the house of a friend of mine. He asked me how he could remove the tree sap from his expensive patio furniture. I said wait a minute, I have a "secret formula" in my truck that should work. I had a 8:1 pre-diluted spray bottle of M-1 in it. The minute I sprayed it on his chairs I could literally see the tree sap disappearing. I let it sit on the chair for a total of 5 minutes and pressure washed it clean. I was amazed, and so was he!! NO residue tree sap and dirt was all gone. My friend said that is the best his furniture had looked since the day he brought it home. Chalk up another useful application to M-1 Deck & Roof Cleaner!! Not just for roofs and decks anymore. I LOVE this stuff!! September 25, 2014
Rated 5 out of 5 by You have GOT to get this stuff Believe me, I have tried everything to clean the algae and mold off the deck and the side of the house where there is minimal sun. I have tried Bleach, shock and other deck cleaners. My neighbor told me to use this. Not only did he tell me to use this, he came over and cleaned my shed to prove it to me. I am SOLD. You have GOT to use this stuff if you have any cleaning to do on your deck or siding (vinyl or clapboard). I diluted it out 1 gallon to 5 gallons. they say to make 10 gallons. I have a pump sprayer and I sprayed it on the most mildew-y part of the house. It was green. I just sprayed it on lightly so that it was all covered. I let it sit for 15 minutes. I used a soft brush...like you would use on your car...after a light rinse and the stuff came off almost completely. No strenuous labor. No scrubbing the paint off. A light brushing and then I rinsed off the mold, mildew and algae. My house looks almost brand new. Really...I am trying to tell you what a great product this is. It saved me a TON of time and it WORKED. A second coat of this stuff and the house really is cleaner than it has been in the 5 years I've lived here. It doesn't kill the plants. It is GREAT. And after you rinse it off and see what a great job it does, in a few hours, it will look even cleaner. It is hard to get across how good this is. When reading these things, you see some good...some bad. For the people who did not think it did a good job...I really have no idea what could have gone wrong. June 2, 2014
Rated 5 out of 5 by Exceeded my expectations I replaced my roof shingles 5 years ago with a light tan color and oak trees hanging over the house had resulted in "tree scum". I was hesitant about harming the new shingles but used M-1 as directed and rather than using a pressure washer, I used a high pressure nozzle on a water hose to rinse. The result is that the affected shingles now look new like the rest of the roof. Azaleas planted directly in the roof drip line were not harmed in the process and I did not cover them. I highly recommend this product. May 9, 2013
Rated 5 out of 5 by Great Stuff! Don't waste your money on anything else! I used in on a deck and roof shingles and the dirt and crud came right off. Anything else I've tried didn't work as well as this stuff. It doesn't have a bad smell at all, and it needs only 10 minutes to work. My deck is small, so I have probably enough left to last me for 10 yrs. June 11, 2012
