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.

Would Recommend[This review was collected as part of a promotion.] Olympic Premium Deck Cleaner worked wonders on my deck. We have a large deck on the back of our house and we use it nearly every night. I had been looking for something to give it a good spring cleaning and this was perfect for that. It was easy to use and it got all the dirt and grime off, making it look brand new! I'll be using this again!

Quick results! Cut through winter grime!
Would Recommend[This review was collected as part of a promotion.] This Olympic deck cleaner did an amazing job on my deck cutting through the grime that had accumulated through the winter. My deck is light gray, and my trim is white, and it frequently gets a greenish algae from the moisture in the south during the winter time. I use the Olympic premium deck cleaner to quickly get the grime off without a lot of scrubbing. I use this deck cleaner last weekend, and it did an amazing job of cutting through t...

OVerwhelmingly the best cleaner ever
Would Recommend[This review was collected as part of a promotion.] THIS was the best cleaner I've found yet. It quickly and thoroughly removed long standing dirt, mildew, and algae. I could see it working, and it kept on working after application. I am so pleased that NOW I have such a clean base to work from and apply stain.

This deck cleaner is amazing!
Would Recommend[This review was collected as part of a promotion.] Great deck cleaner. We have lots of birch trees in our yard that drop everything. When I saw this deck cleaner I had to get it. This Olympic deck cleaner was so easy to use and my deck is so nice and clean and looks great with my new stain on top.

better than just pressure washing alone
Would Recommend[This review was collected as part of a promotion.] I really put this Deck Cleaner to the test on some hard stains. Since it can be used for more than decking, including siding, I decided to start from the top down. It is nice that there is no mixing needed, but the bottle would be better if it came with a sprayer rather than needing to put it in a different container to be able to use it. It says "virtually" no scrubbing required, but I found the results are better if you do put at least a litt...

Works Great!!
Would Recommend[This review was collected as part of a promotion.] I got the Olympic Premium Deck Cleaner a few weeks ago, and it works great!! It removes dirt, mold and mildew. It is ready to use and required very little scrubbing. Apply it and let sit for 10 minutes, then wash off. It left my deck looking gorgeous!! I can also be used on concrete, which is great. I love all PPG products and this one did not disappoint! I highly recommend this awesome cleaner to everyone!!

cleaned the green off my shed with no scrubbing
Would Recommend[This review was collected as part of a promotion.] I wanted to try this deck cleaner because it says it can be used for multiple surfaces. I like that because it means I don't have to get multiple different cleaners for different things. I started out using this on my shed. One side is in constant shade so the bottom of the wood is green from mold/mildew. I tested a patch before doing the whole area, and you can see in the pictures the difference from where I used it and where I did not. I like...

Fantastic Product & Easy to Use!
Would Recommend[This review was collected as part of a promotion.] Easy to apply, was very strong odor and recommend a respirator when applying. The product is amazing and exceeded recommendations! My client was very happy with the results. I did not spray but slot coated with a deck brush with very proven results!

A deck refresh!
Would Recommend[This review was collected as part of a promotion.] We utilized Olympic Premium Deck Cleaner on our 8 year old pressure-treated wooden deck and are very pleased with the results! This solution is simple to utilize, and we opted to utilize a gentle sprayer to apply to the decking. Let the product sit for 10-minutes or so, and although scrubbing is not required, we did utilize a gentle brush to remove some grit and grime. Rinse, and voila! Our deck, with only a thin layer of transluscent stain ...

No scrubbing
Would Recommend[This review was collected as part of a promotion.] I’m pleased with the effectiveness of Olympic Premium Deck Cleaner. I even used it to clean my patio. It’s easy to use, and there’s no need for scrubbing. It gives me the results I want without the extra work that I don’t want.

Great cleaner
Would Recommend[This review was collected as part of a promotion.] I got Olympic deck cleaner. It works great and is very easy to use and apply. It left my wooden deck looking clean. It came in a very large size so there was plenty of liquid to use on an average size deck.

Terrific results
Would Recommend[This review was collected as part of a promotion.] Our deck is approximately 450 sq feet. This package says it will clean up to 350 sq ft, so I purchased another gallon to finish the job. And what a job it did of cleaning our weathered gray decking. The before and after photos barely show the huge difference. After a long winter of harsh weather, our open-air deck was in dire need of cleaning, and this product worked great.

NOT A CLEANER
Would Not RecommendI wish I would have read reviews on here first! Same experience as many people. Applied the "cleaner", definitely more like stripper, for 5 minutes and rinsed! Now the wood is blotchy and fuzzy! DO NOT BUY THIS! My deck is only a year old and it looks horrible! Now instead of my next step being stain, I have to figure out how to fix this. Take this off the market or rebrand it as a stripper.

Olympic deck cleaner
Would RecommendDO NOT USE IT'S JUNK!!!! Cleaned my 500 sq foot deck using 2 different products and Olympic deck cleaner is pure JUNK sorry to say! It stinks of bleach which is not what you want to clean a deck properly! It was also 50% more than Behr deck cleaner which performed much better than this garbage. You guys should pull this product off the market as fast as you can. You should also be embarrassed to even sell this junk! It's 0 on the scale not even a 1 but they won't allow a 0 as a rating!

Stop Pressure Washing!!
Would RecommendOlympic Deck Cleaner is one of the top products out there. All of the complaints out there about how the wood is turning out, I would bet they are not telling the whole story. First, let the cleaner do it's job. Put the power washer away! Your are only destroying the wood and prematurely aging it when you blast 3000 psi of water into wood, particularly if it's dry and never had a protectorant applied! Second, if you've neglected the wood or have inherited a worn deck, whether you use ODC or some...

Olympic Premium Deck Cleaner Isdurs
Would Not RecommendJust bought 2.5 gallons of this product to use on a 2year old deck…after using SealOnce sealer on it a year ago. First used it on the top rail & got the results in the photo…fuzzy finish as if it had been pressure washed on high setting. This wood has never been pressure cleaned. What’s happened & can it be fixed????

Olympic Deck Cleaner is the Best!
Would RecommendAbout every 4 years I have used Olympic Deck Cleaner prior to using Olympic Honey Gold Stain. The deck cleaner delivers a look like the deck was just built - and its now its over 20 years old. I spray it on and brush off the black film and mold and it looks brand new. I included a photo below - highly recommend!

Horrible!
Would Not RecommendCalled company to ask why people complained about this cleaner. Was told it works as long as you don’t let it dry. I soaked this and this is the result! How can they continue to sell a “cleaner” that ruins wood?!
