Cedar WASH Eco-Safe and Organic Wood Cleaner 10 lb Container

My cedar sided shed is 20 years old and the front side facing the sun was totally grey. Here is what I did……. I took a 5 gallon bucket and added1 gallon of water to it. I next added 1 cup of this product to it and then used my electric drill w/stirring paddle to mix it up for about 13 min. I took this 1 Gallon mixture and put it into a 1 gallon sprayer. I started spraying at the top of a wall and could immediately see a dark sludge flowing down the wall. I scrubbed the siding with a handheld good bristled brush. You will be amazed at how gunked up the brush gets and what’s flowing down the wall. Every minute or so I would take the garden hose and spray clean the brush and then back to brushing the wall. Once I got the all the wall brushed, I took the hose on jet spray and hosed the wall down thoroughly. Since the siding was exposed to cleaner and water it still looked pretty dark but I could see various spots of patches of red showing through. After the shed thoroughly dried after about 4 hours, the wall looked great about 90%. I touched up a couple of areas and am now 100% satisfied. This product worked fine for me but I had many doubts after reading some reviews.

I have approximately 500 sq. Ft of rough cut cedar siding. My siding had many decades of build up to the point it just looked like black siding. On contact you will see residue running to the ground. Sprayed it continuously and let it sit for 15 and up to 30 minutes and repeated process using a 3000 psi pressure washer with 45 degree angle. It was lightening up but wasn’t stripping the cedar like I wanted. So I resorted to 15 degree angle on the pressure washer and about 2 inches from the siding. Washed with the grain. Yes it raised the grain in some areas but in the end I had a light colored cedar. Later on after it dried really well I sealed it with clear sealer and it brought out some of the red again. I don’t have before pictures but I posted some of the “after sealer” results. It’s been two weeks since I completed it. These pictures are in the shade and doesn’t really show the full color. My main point is, this product doesn’t work miracles nor did I expect it to. But it did help with the process. Scrubbing wasn’t an option. I ruined several brushes trying to scrub it. Brushes were full of oil.

Follow the directions, including mixing times, and you will be happy with the results. Be sure to use a pressure washer.

I used this product at max strength - one cup/one gallon water on shingles on the side of my house. My cedar shingles have not been cleaned in 20 years. Mixing is really important to fully activate the product. I mixed one gallon at a time, sprayed it on and let it sit while I mixed another batch. I used a hose with a spray nozzle to wash it off because I was worried about the damage a power washer might do. Worked great! The only area I had to scrub (lightly) was the bottom two rows of shingles that were covered with algae. You may want to cover your windows though - whatever came of the shingles left a gooey film on the glass that was really, really hard to get off.

I was shocked and amazed at how easy this was. Zero scrubbing at all. I sprayed on, let sit for 5-10 minutes and sprayed off with a garden hose. It was wild to watch black colored water run down and the natural color of the cedar shake come back to life. We thought the home we just bought would have to be painted. This product is amazing!
