Olympic Stain Premium Deck Brightener & Wash, 1 Gallon

Love this product for cleaning my composite deck. The only deck cleaner I will buy

I used gallons of this product for years and was very pleased. It worked beautifully cleaning decks/sidewalks. Unfortunately, the last two containers of product failed to clean??? It makes me wonder if they have changed their formula.

I'd never used a brightener before, but it really made a difference with stain on older wood. Highly recommend! Worth it.

I had used Olympic Deck Wash for several years both on wood and vinyl surfaces. The older formula smelled of strong clorox, but all you had to do is spray it on, and the stains just disappeared in an hour or two then just rinse with hose. This included those nasty black stains you get on pressure treated lumber, but it also worked great on vinyl thigs like lattice, fences and my vinyl tool shed. Green or dark mold instantly gone. This new formula has no smell of clorox (which is the only nice thing about it), but it doesn't clean hardly anything without scrubbing it with a brush after letting it sit for 30 minutes. I found that if I wet the brush with water and dish washing liquid, it was just as effective as this newer version of Olympic. A pressure washer is probably just as effective, in fact that is what I'm going to try on the stuff I didn't yet get cleaned. Big disappointment, also, I noticed the price of this is abut three times what the old stuff cost which you could buy in home improvement stores, but they don't carry it any more which is why I bought it online.

The product did not wash away/remove discolored spots where rain puddles with leaf/needle bleed had discolored the Trex deck. It did lightened the gray color tone of the deck accentuating the darker water stains I was trying to remove. I followed the instructions using a pump sprayer, brush, and a power washer at 2500PSI.

"My two-decade-old Trex deck had darkened due to exposure to city dust, organic debris from trees, and other environmental factors. Despite attempting to clean it with different soaps such as dishwasher soap and all-purpose cleaners, the grime persisted. However, this specific product worked very well. Following the instructions - wetting the deck with water, applying the product, allowing it to sit for 30 minutes, scrubbing, and rinsing with a hose - yielded a good outcome. A second application further improved the deck's appearance, leaving me highly satisfied with the final result.

Not sure this is a fair reveiw of this product but I used it on my new but dull and dirty TREX deck and it doin't help at all. It was what Trex recommended when I contacted them.

I have used this product for years and love it!!! Unfortunately none of the stores that had it no longer stock it. If you have a natural finish deck, you need this. Hose down the deck, apply with scrub brush, wait 1/2 hour, rinse and all the dirt from a MI winter is gone. There is another product you can use as step 2, the brightener. Apply with a scrub brush, let sit 1/2 hour, rinse. When dry, the wood looks brand new. Once surface is dry, you can apply clear coat, no need to wait days like other products.
