Questions & Answers

How long before seeing results

Asked by: Jk
I saw good results immediately after hosing it down 10 minutes after application.

applying with a power washer

What is the correct dilution if i am hooking it up to a power washer, as the power washer itself will provide for a dilution during application?
Asked by: diyer
I used a separate spray bottle (went heavy on the concentration) and sprayed my GAF 30-year asphalt shingle roof, waited about 15 minutes, then (light-setting) hit it all with my pressure washer. Worked fine. Got years of nasty mold and mildew out of the roof, restored it to "like new" condition. I discerned minimal "shingle skin" loss.

Does anyone have any experience with using this product on asphalt shingles? I have not had much luck on shingles.

Just rinsed with water, did not want to use pressure washer on shingles. Will it work with pressure washer?
Asked by: Jeb58
I have used it sparingly on dark spots caused by overhanging oak trees. I sprayed generously and hosed off with a normal water hose after about 10 minutes and it cleaned up quite nicely. I believe the key is to do it when the sun is shining on the shingles you wish to clean but that is merely my opinion from my own efforts. It's a good product.

What is the active ingredient?

What is the active ingredient?
Asked by: JR
The only ingredient I see on the label is sodium hydroxide so I assume that is the active ingredient.

My deck was not very dirty but had dark grime and moss and this product worked very well followed by a pressure washer after the 10 mins with 15 degree tip. This removed all dirt and grime. Directions are pretty clear.

Rated 4 out of 5 by from I'm a bit surprised by the disparity of reviews here. I'm happy with the product, which is basica... I'm a bit surprised by the disparity of reviews here. I'm happy with the product, which is basically soap and lye. I used it on my redwood deck. I diluted it 9:1 as per directions and sprayed it on. Left it there around 10 minutes ,then brushed, then hosed off. I did not use a power-washer. It brightened the wood (which you don't see until it's dry, at least with redwood). It did roughen the surface, with bits of wood sticking up. It took off a bit of oxidized wood- you can see the color of the water when you hose it off. It takes a lot of hosing to get it all off because soap is hard to completely wash off. You'll see that it's still a little foamy and that could make the surface slippery. I'd suggest using it the day before a rain so you can get extra rinsing done by the rain. I have some painted wood around my house that was dirty and mildewy. It did a very good job cleaning that off too. It does a decent job getting rid of mildew but if your problem is only mildew you're probably better off with bleach. I guess it's possible that different wood has different issues and maybe even different types of mildew. Brushing helps but note that if you brush against the grain you're going to roughen up the wood.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.
