Q:Will this cleaner work to remove sap from my wood deck?

Answer This Question

A:  Don't know about sap. It definitely removes mold. If you try it, use it on a cloudy day or in the shade. You have to let it sit for 5 to 10 minutes, then scrub with a hard bristle brush and rinse. Hope this was helpful. Good Luck.

      A:  Not something I would recommend. This stuff is pretty strong. Can cause skin issues with contact. Ventilation would be critical.

            A:  In my opinion, it’s the best deck cleaner “hands down”!  I’ve been using this product for at least 10 years, and not only does it do an awesome job, but it’s extremely easy to use!  Just use a pump sprayer.  Wet down the deck with water, spray this cleaner on an approx. 10’ x 5’ section, wait 5 to 10 minutes, then wash it of with a hose.

            by|Sep 12, 2022

              A:  Hi Chris, you will want to thoroughly wash the deck hardware and ensure that the product does not dwell on it.

                Product corroded through container and leaked on to leather baseball mitt in garage, putting a hole in the leather baseball mitt. Also, do not recommend using with leather work gloves. Product did clean composite deck well.

                  Olympic Premium Deck Cleaner Isdurs
                  Just 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!
                    About 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!

                      Called 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?!

                        No noticeable difference….
                        Our deck is about 10 years old, never treated, never stained. It had weathered well but was definitely very dirty from years of use. We gave it a hearty power washing over two days, but there were still a few spots we missed and a few spots we thought a deck cleaning product could improve upon. I applied this product liberally (to lightly foaming), let it sit for 10 minutes or a tad more, then rinsed well. There was really no noticeable difference. In some spots, where the boards were fairly well clean, it just faded the board (kind of like bleach would do). We had one spot we totally missed that was covered in dirt and algae/moss; after application, it was absolutely the same. I’ve attached some before and after pics (top 2 of one area, bottom two of a second area) and the last pic on the bottom of the spot we’d missed after the application of the product. You can see the results; it just didn’t live up to the hype. So…very disappointed, and I would not recommend this product. Honestly, if there were a guarantee, I’d request a refund. Total waste of money for us.

                          DO NOT use on COMPOSITE decking material
                          I recently used this cleaner on my composite wood deck. It did an okay job of removing stains but now I have a bunch of areas on my deck that look worn away. It’s like this cleaner stripped the color off my deck. In my photo, the left side is where I used the cleaner and the right side is where I just power washed. Perhaps I left it on too long? Not sure. I’m just glad I ran out of the cleaner and didn’t bother to go buy more.

                            Chose this product!
                            This product is the best in terms of how effective and easy to use it is. I started on the back deck, power washing, using this cleaner, scrubbing it in then power washing again and it looked great. By the time I got to my front porch I was warn out and skipped alot of steps. I put it in a spray bottle and sprayed it on and like magic it melted the dirt and grime away (even better then all the scrubbing and powerwashing!) I included a picture of what it looked like after just being sprayed on. The only con with this porduct is it does have a very strong smell, if you are sensitive i would recommend wearing a mask. It did irratate my hands a little bit and made holes in leather gloves where product got on.

                              As part of getting my front porch ready to stain I figured I'd use this product to give it a good cleaning as the final preparation step before applying the stain. The surface was in good condition but the previous coat of sealer was 5 years old. I applied this cleaner following the directions to a T (applied with a sprayer waited 10 minutes and then rinsed off). As I started rinsing with a hose, I noticed the once smooth deck surface was now rough and what was the previous coat of sealer was being washed off. When finished rinsing, I was horrified with the final result - see photos. So instead of having a nice clean, smooth, ready to stain deck, I had a very rough deck that needed help and now had to buy a sander and paper to the tune of about $115.00 and spend 6 hours sanding the deck making it ready for stain again. I'd highly recommend that you DO NOT use this product!!

                                Amazing Product!
                                This is my first review am ever as I am usually hesitant to review a product. But this cleaner is the real deal. I used 3 others power washer ones and then I purchased this one and it did the trick. Highly Recommended and no power washer needed.
