What Customers Are Saying
The product effectively removes mold, mildew, and dirt from decks, often restoring them to a like-new appearance with minimal scrubbing. However, some users have experienced issues such as wood discoloration, residue, or damage to composite decking. It's important to follow instructions carefully, including letting the cleaner sit for the recommended time before rinsing and potentially using a brush for stubborn spots. While generally effective, a small percentage of users have had disappointing or damaging experiences, so testing the product on an inconspicuous area is advisable.

Cleaned my deck beautifully
[This review was collected as part of a promotion.] When I got the Olymic Premium Deck cleaner I wasn't sure if it was really needed. I was very wrong about that. It lifted dirt from my wood after using it that water just didn't get alone. It was easy to use and didn't leave a chemical odor behind.

Amazing product warning label should be updated.
Would RecommendWarning label should highlight at there is alkaline acid in this product and to wear a full suit it cannot come in contact with your skin at all. When I washing my deck off, fine mist rolled up, got me in the face Ended up going to the ER and had 101 fever. my face became swollen in the spots that come in contact with the alkaline. It burns slowly you won’t feel it right away. Nothing appeared till the next evening.

Works Well for Light Work
Would Not Recommend[This review was collected as part of a promotion.] I used the Olympic® Premium Deck Cleaner on my wooden deck, and while it did a decent job, there were a few areas where it fell short. The product worked well to remove general dirt and mildew, leaving the surface much cleaner than before. However, for tough stains, especially those that had been there for a while, would require quite a bit of scrubbing. One of the product’s best features is its ease of use for light work. It applies evenly an...

Be patient; results develop as surface dries
Would Recommend[This review was collected as part of a promotion.] PPG Deck Cleaner is a potent product that does a remarkable job on wooden decks, and does a pretty good job on concrete/aggregate driveway surfaces. First, please note that this product should be carefully stored because it will bleach anything it contacts. The instructions are to use this cleaner full strength using a pump-style sprayer; they also say to not scrub. I discovered that our sprayer is broken, so I had to improvise and use a t...

Used with sprayer not included
Would Recommend[This review was collected as part of a promotion.] Olympic Deck Cleaner, can be used on multiple surfaces such as wood and brick. In order to use the cleaner I had to purchase a sprayer to put it in to apply. There is no mixing, I simply put into the sprayer, sprayed onto the mildew on a small section of my deck boards first to test and let it set for approximately 10 minutes, rinsed off using a garden hose. It cleaned those boards nicely, with just some easy once over with a brush. Labeling st...

So quick and easy!
Would Recommend[This review was collected as part of a promotion.] I used this deck cleaner to get my composite deck floor looking new and natural again! It was so grimy and I loved seeing all of that dirt wash away after letting this cleaner just sit for a little while! We have had a ton of rain here lately so there was also some mildew build up and I was shocked to see that I didn't have to scrub! This cleaner just washed it all away! It is quick and easy to use, right out of the canister!
