KÄRCHER Multi Purpose Pressure Washer Detergent, Highly Concentrated

I picked up the Kärcher Multi-Purpose Pressure Washer Detergent and it absolutely delivered beyond expectations. This stuff cuts through dirt, grime, and buildup like it’s nothing—my patio and driveway honestly look almost brand new again. What I love most is how versatile it is. I’ve used it on siding, concrete, and even outdoor furniture, and it works great across the board without any issues. You don’t need to use a ton either—a little goes a long way, which makes it a great value. It works perfectly with my pressure washer and produces a nice, even clean without leaving streaks or residue behind. The whole process felt quicker and easier compared to other cleaners I’ve tried. If you want professional-level cleaning results at home without extra effort, this detergent is a must-have. Highly recommend!

love the mix of 40 gallons. used with my new pressure washer on siding that doesn't get a lot of sun so had alot of green. Sprayed on and let sit 5 minutes. Power sprayed right off. Doing my non finished deck next to prep for stain.

Worked very well on our concrete patio, it looks great!

This is for the General Purpose Cleaner for pressure washer! I purchased this when I moved into my new home. I had to get a pressure washer because the outside porch was so dirty, so of course you had to get the soap too! I highly recommend this one. There were a few to choose from but for this price point it worked fantastic! You don’t need a lot of soap to get the job done. I’m aware this also depends on your pressure washer but soap didn’t fall flat-see before and after photos. Thank you.

Good product, but left out on my driveway

Bought a small pressure washer. Put the cleaner in a bucket with water and it worked wonderfully! I then had a second bucket with clear water and then rinsed the soapy water. Used this method on my deck. My husband used this to wash his car and It worked great!

Why did you pick this product vs others?: This detergent works really well with my pressure washer. I used it on the siding on my house—it cut through dirt and grime without any scrubbing. What I really like is that it’s not overly harsh or chemical-smelling. Great value for the size. If you use a pressure washer and want something that just works without the hassle, I definitely recommend giving this a try.

Worked well ough stains.n to

Works as stated and with the 19 to 1 ratio this 3.78 L bottle will last a long time. I just used it on the side of my house with good results,lifted the dirt and grime on my vinyl siding and was easy to rinse off.

For the price and quantity it's a good deal. it work ok and give positive result.

still had to really scrub my vinyl siding to get it clean

Very satisfied. This product works really well, we cleaned our deck manually, and it still worked really well, the green moss got away easily. But I think we might need to apply brightener or varnish later on.

Bought this to use with my new low powered pressure washer meant for cleaning my composite deck. It did a good job. Much better than a pail of soap and a deck brush. Also cleaned overhead canvas canopy and a birdbath. Too much fun. I had to make up a marked mixing jug to get the concentration right so it will be easy from now on. I believe this product to be good value.
