Rated 5.0 out of 5.0 by DianeMayo Expert Chemical Composite Deck Cleaner
In ten years we never could get the deck clean and bright as the Expert Chemical composite deck cleaner did. We have tried many other products and even straight bleach-------nothing worked. When using other products, after all the hard scrubbing, the deck appeared better for only a few weeks. It soon returned to the dirty looking deck. It was very depressing. It looked so bad we didn't use the deck any longer
After receiving the composite from Home Depot. we went right to work. The directions and video were so clear and the job so easy and the results so satisfying
We have recommended the Expert Chemical Deck Cleaner to all our neighbors who have a composite deck and will continue to recommend it. thank you Expert Chemical. Diane Mayo

Rated 5.0 out of 5.0 by Jim Finally - A Product That Works!
Over the years we tried several different mold cleaners for our composite deck along with pressure washing. Most didn't work at all, others worked short term with the mold growing back fast and heavier. It got to the point we were ready to rip out the 5 year old, 400 sq. ft. deck and replace it with concrete.
Although there are 3 application steps, you will see amazing results after step 1. In our case 90% was gone before scrubbing started in step 2. (Our light grey deck shows the mold best when wet.) I plan to use this product every spring because it really does make the deck look new again.

Rated 1.0 out of 5.0 by Kevin Made my deck worse, only did half of the deck
I have a 800 sq ft deck, so I purchased 8 bottles for $180, plus a pump sprayer, gloves, scrub brushes, goggles. Watched the video and read the directions to be sure to get it correct. I split the deck into two parts, so I could follow the directions exactly. The part that I cleaned is actually worse than the side that I didn't clean. This product is a total waste of money. Do not purchase it. Returned the remaining bottles to Home Depot, but they would not refund me for the product that I used. Stay away!!!

Rated 5.0 out of 5.0 by rgf427 Very very satisfied!!! Have been looking for a product that produces these results.
Very very satisfied with the results, the application, etc. Immediate results and the decking looks much better than it has for some time. I found it convenient to be able to let it dry in one area as I work on another and then come back for the second and third applications. Black spots disappear after first pass and the deck now has a slight sheen which makes it look newer. It has been difficult trying to find a product that is relatively easy to apply and quickly removes the mold, black spots, etc. They seem to be available for awhile and then are discontinued. I hope I can rely on and plan on this product being around year after year! I'm tempted to try their house wash now.

Rated 5.0 out of 5.0 by schmoooz I dont care what you read this stuff REALLY WORKS!!!!!
I read all the reviews and bought this product. Followed the directions and used it. I actually bought too much and made the choice to do the scrubbing process twice because I have a light brown trex deck that I have not cleaned for about 7 years. The last time I used a pressure washer and some other product and could not see much of a change. So this year I said its time to clean it. The deck had mold and was nearly black and I dreaded cleaning it. I watched the video and decided to spend a little more money and give it a try. What I can say is WOW my Black Ugly Deck IS NOW THE ORIGINAL BEIGE color it was when it was installed. I used a pressure washer and it looks great. I now enjoy my deck and cook on it all the time. What I will say is it is strong and you may get bothered by this with smelling it after some time. I also have some painted areas on the deck sides and stairs it did wash that color quite a bit but I can repaint that. What I will say is it did what it said it would and I am very pleased with the results. There was also a strong odor left for about 2 days but that went away also. So my advice is this is worth the money and is a great product.

Rated 5.0 out of 5.0 by cardinalgirl Works great!
This product worked great on my trex deck! If I would hve ordered extra, it would have finished off some remaining darker areas. But it's expensive @ almost $19/gallon which covers 100 sq. feet and my deck is 800 sq feet-ouch! :(, so I tried to be conservative but still used 7 gallon which computed out to $133 just to clean the deck. I didn't have enough to give it a second coat as it says, but will definitely use it again. Our deck is very shaded with trees and is on the north side of the house which contributes to mold, and stains from multiple leaves in the fall. The actual color of the trex is saddle, but it looked more like walnut before applying the deck cleaner as you can see in the photo.

Rated 5.0 out of 5.0 by Hawkmeister Couldn't be happier
I hadn't cleaned my composite deck in about 2 years. It was easier to use then the Corte*Clean product previously applied in the years prior. That item was increasing becoming hard to find. So, I switched to something new.
I treated a small area of my deck with the chemical (just dripped out of container). Attached is a photo of it after sitting for about 10 minutes. No scrubbing was performed. All of the green mold disappeared.
I have 200 sq ft deck and used 2 gallons. It barely made it on the second application.
Overall results were great. I will purchase this again next year.
