It's a concentrate but I just it straight. Nice suds, takes off dirt and smells good, but not overpowering. Better than cleaning with just water doesn't.seem to harm plants or grass.

I needed a good detergent that is safe on hedges and plants and still has some cleaning power. I used this with my pressure washer to clean siding and eaves on our house. The detergent loosened up dirt, mud wasp nests, etc. allowing the pressure washer to remove it easily. Overall, a good detergent.

I ordered this product about a month ago. I used it for the first time last week and it is the cleaning product I have ever used for my sidewalks and concrete patios.

This all purpose Karcher detergent works awesome with my new Karcher 2000 pressure washer. Cleaning my driveway and house was a breeze.

[This review was collected as part of a promotion.] I try to powerwash our home every spring/summer. Other brands we used, would leave a bleachy or industrial-type smell that would seep into the house, triggering allergies. This point alone would have me jumping from different detergents, some smelling great, but lacking in their cleaning power, which also created a problem. Then I used Karcher's All-Purpose Detergent for power washers, this is an awesome product. Karcher has great cleaning power and it washes off easy. But the kicker for me was after already proving its cleaning power, the smell of the product wasn't overpowering, it was faint but a pleasant smell that didn't trigger any allergies. I highly recommend this product and will be using it again.

I don’t dilute it as much as they say, because I like a little more foam. It definitely helps if you let it sit for a minute or so before rinsing. You’ll still need to scrub some if there are things stuck on, but overall it loosens up dirt and doesn’t harm the plants.

[This review was collected as part of a promotion.] I have tried other products and they just weren't as good as Karcher's. I didn't get all of the leaves off of my patio this past winter and the leaves stained it. I thought I would have to paint my patio. I got this detergent and I was amazed on how well it took off the stains. Yay! I do not have to paint and my patio looks like new.

[This review was collected as part of a promotion.] I just finished power washing my entire deck using this Kärcher - All Purpose Detergent 1 Gal. 20x Formula. I followed the directions for mixing and used the sweep sprayer on my power washer and I couldn't be happier. My deck had dirt, some black discoloration on the decking, some green mold on the railings and the furniture was filthy. It powered off everything and got everything clean and back to the original color. Next week I will be doing the front porch and the siding on the north side of my house.

[This review was collected as part of a promotion.] I was excited to try this because I needed to pressure wash my garage. I have used water and it kind of works so I needed to try the Karcher multipurpose pressure washer cleaner so see if there was any difference. Well there is a huge difference. Water just gets the top layer of dirt washed off whereas the Karcher multipurpose cleaner really cleans deep down. I have been doing some pressure washing each evening and it is so much cleaner and less work to use the cleaner. I am very happy with how my garage looks now. It looks like I spend hours scrubbing the dirt away. Tonight I want to do my patio set and see how great that will look. I also have a cement patio that will be done with weekend. I also will try the garage floor, because I have not pressure washed it. It is so easy to use, I use about 6 and a half ounces of cleaner for a gallon of water and I am ready to go. I really am amazed how great my garage looks after using the cleaner, that I won't go back to just using water again. This is a great product to use for all the summer time clean ups I like to do.

Feel like it did not work very well. Would double the concentration
