[This review was collected as part of a promotion.] Didn’t work better than any other cleaner I have tried. Pressure washed and scrubbed and still have oil stains in my driveway, albeit they are older stains so maybe this works better with new stains. Smells decent enough and is eco friendly so that’s nice.

[This review was collected as part of a promotion.] This product works to clean my pool patio tiles. I have residuals from trees and the lake that stain my tiles and this worked to take it out. It has a citrus scent that's a bit strong but not too bad. It was well packaged and is a great value for the amount of liquid to clean a large patio or driveway.

[This review was collected as part of a promotion.] The Karcher Concrete Patio Cleaner works really well! It easily cuts through dirt and grime, leaving my patio looking fresh. The scent is mild, not too strong, which I appreciate. I also like that it works on driveways and sidewalks too. Super easy to use and gets the job done!

[This review was collected as part of a promotion.] This concentrated concrete and driveway cleaner by Karcher works wonders and is easy to use. For heavy cleaning, instructions recommend 1 part concentrate to 4-10 parts water, and for light cleaning, it recommends 1 part concentrate to 39 parts water. Once applied, using a pressure washer or manually, let it soak for a few minutes and then spray down with water. My husband added this to our pressure washer to clean the driveway, and I spot cleaned some concrete areas. I definitely saw results, and it helped clean oil and dirt stains easily. The nice, citrus scent is a nice bonus. Overall, the results were fantastic, and I would absolutely recommend this cleaner to freshen up your driveway!

[This review was collected as part of a promotion.] Our driveway is covered by trees. Birds are flocking to the trees every evening and leave droppings everywhere, every day. It ends up mixing with dirt, mud, road grime and stains our driveway very badly. I have a Karcher pressure washer so this product is a must have. I add it into the tank and it takes the grime off with ease. Without it I have to pretreat the driveway with another “cleaner” and wait almost an hour for it to “work”. This stuff is like magic eraser for driveways.

[This review was collected as part of a promotion.] The Karcher Concrete & Driveway Cleaner works excellent for cleaning concrete driveways removing dirt & oil effectively. It leaves the driveway looking very clean & works better than just pressure washing alone. Very easy to use with the pressure washer & it doesn’t leave residue.

[This review was collected as part of a promotion.] Great product, works efficiently and effectively. I appreciate that the directions are easy to read, but I wish they included guidance on which dilution ratio is best for specific surfaces. Plus the information doesn’t include anything about if I should avoid vegetation which is very useful. I used the medium duty mix on my concrete driveway with a pump sprayer. It worked well for small stains and stuck on dirt, but it didn’t remove oil stains. After pressure washing, I compared treated and untreated areas, and you could clearly see the difference where I had used this cleaner. Another small but nice detail is that the bottle design prevents liquid from spilling all over when pouring, which is a plus. Overall, a solid cleaner for general concrete and patio maintenance.

[This review was collected as part of a promotion.] This cleaner works! I use this all the time in our shop when cleaning because it easily dissolves and removes the grease. We have an industrial shop where grease can be all over the floor, either caused by lift oil leak or little spill from doing a project, this cleaner works great even though we had refinished our floor. I think it’s mainly because it’s concentrated and depending on how much grease or dirt we needed to remove, we can easily adjust the concentration needed. I know it says it’s for concrete, but it works just as well in the type of floor we have and it’s not slippery when it dries, it’s why I mainly use it.
