Rated 4.0 out of 5 by 21 reviewers.
Rated 5.0 out of 5.0 by Ready for Staining Without Much Effort Easy and effective without much effort. Spray on, brush in, and power wash with a Home Depot power wash and your deck is ready for staining. This product took off over 10 years of dirt and grime. Wear protection as the chemicals are strong and irritating on the respiratory system. June 10, 2015
Rated 2.0 out of 5.0 by Ok, but need more than garden hose pressure to work properly... Bought this product to clean black streaks off my roof. At first glance did ok job to brighten lighter stains, but as for the darker stains it turned into a gummy mess that took a very long time to get off with a garden hose. Switched to 50: 50 mix of bleach and water - worked like a charm! August 27, 2015
Rated 4.0 out of 5.0 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 5.0 out of 5.0 by No complaints I've used this on my deck once so far and I couldn't be more pleased with this product! Any stains that were on my deck are now gone. I echo what another reviewer said in that it's best to do this on a rainy day. I'd recommend this to anyone with a deck that's in need of a bath! July 7, 2015
Rated 5.0 out of 5.0 by Works Like it Should Works exactly like it is supposed to. I used this to clean my deck before painting it. All the stain applied well. I'm very satisfied with this product July 1, 2015
Rated 5.0 out of 5.0 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 5.0 out of 5.0 by works great i have been using this product for more than ten years now.i found that if you are cleaning your deck its best to do it on a rainy day,because the deck needs to stay wet the whole time. mix it 9 to 1,and spray it several times and just keep it soaked with the cleaner and a wet surface for an houre and rinse ,when the sun dries it out it will be cleaner,clean enough to stain.never p.w. a deck it will ruin the wood.
