[This review was collected as part of a promotion.] I'm very happy with Kärcher's - All Purpose Detergent 1 Gal. 20x Formula. I can clean so many different things with this product. I but some in a spray bottle added water and used it to wash some items around the house. I had my son put it in my pressure washer and wash off my patio furniture and tables. It did a nice job. He also cleaned off the dirty patio with it. It all came out nice and clean.

[This review was collected as part of a promotion.] This is the first cleaner that I've put in my pressure washer and it sure did make pressure washing my pool deck much easier! I have to clean my deck at least twice a year, but I never used any cleaner with it...I didn't realize what a difference it made!! I also cleaned up several concrete garden statues that I have in the yard. They had gotten moldy with green stuff growing on them but now they look brand new!! What a great product!!! Wish I had known about Karcher- All Purpose 20x Formula long before now as it would have made my life a little easier!!!

[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.

[This review was collected as part of a promotion.] This all purpose detergent was perfect for the mold and dirt on the side of our house as well as the driveway, sidewalk and our car. It cleaned up everything really good, no residue left behind. I was pleasantly surprised at it's multiple uses. If your on the fence on rather to purchase this or not for the pressure washer, go ahead, you will not be disappointed. This is definitely a plus for the Humidity in the South and all the mold and fungus it leaves behind.

[This review was collected as part of a promotion.] I'm really happy with this all purpose detergent. It was the most versatile and efficient all around cleaner I've ever used. Removed mildew and dirt with no problem. This can be used with pressure washer equipment or manually to clean many exterior surfaces.

[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.] This Karcher detergent cleaner for pressure washers is just what I needed for my home spring cleaning project. It helped make cleaning all of my concrete easier with this. This gallon size is huge and will last me quite a bit of cleanings. I like that it is the same brand as my pressure washer as well.

[This review was collected as part of a promotion.] Kärcher Multipurpose Cleaner for Pressure Washers gets the job done! So far we’ve only used it to wash our vehicles, but we also plan to clean the siding on our house and maybe the sidewalks or even the driveway as well. It is extremely easy to use, and the amount of foaming suds this soap creates helps to know it is working as it should. One gallon actually makes up to 20 gallons when you place the siphoning tube into a diluted mixture or pour the diluted mixture into an onboard detergent tank, depending on the style of your pressure washer. The results are best when applied to surfaces with low pressure and letting it sit a few minutes, then using clear water at high pressure to rinse it off. We found that no brushing is necessary, but that may depend on how stubborn the dirt is on whatever it is you’re cleaning. We will definitely continue to use this product and highly recommend it!

[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 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.
