    • Transformed my car care routine – even the driveway looks cleaner!
Style: Heavy Duty Cleaner
This product has completely changed the way I care for my vehicles. After trying Kärcher Vehicle Wash and Wax, I haven’t gone to a commercial car wash since — and I honestly don’t plan to. Washing my cars at home has become not just a chore, but something I genuinely enjoy. The detergent is powerful yet gentle. I simply spray it onto a wet surface, wait about 3 minutes, and rinse it off. For especially dirty areas (like the wheels or lower panels), a light scrub is all it takes. The results are amazing: my vehicles look spotless, with a beautiful glossy finish that feels freshly waxed. One unexpected bonus — after washing the cars, I noticed that even the concrete driveway where I wash them looks cleaner! That’s how effective this formula is at breaking down dirt and grime. It doesn’t just clean your vehicle — it freshens up the space around it. It’s safe for cars, trucks, bikes, even boats — and it smells nice too. I genuinely feel like my cars are happier and more cared for after each wash. This product saves me time, money, and gives better results than the average car wash. If you take pride in your vehicle or just want a convenient, effective cleaning solution — this is it. Highly recommend! ... show more

    • Like brand new
Style: Vehicle Wash & Wax
Dilution rate is 19 water to 1 Soap and initial wash used too much soap but clean as a whistle and a little dull but another washing and chammie cloth finish and it shines and water beads well. Minimal environmental warnings. Jimmy like!

    • Decent, smells good.
Style: Vehicle Wash & Wax
Works well. It is not concentrated so you will use a lot. Not a bad thing. Just be aware you will use more than a concentrated detergent. It smells good. Foams up well. I used it on my boat. I will use it and when it's gone I may try a different brand.

Sprayed clean with no clogging and broke through YEARS of grime from my home without any damage or fading of the paint. Worked well on concrete sidewalk as well.

Worked great! Didn't get much foam action, but I think I just need to play with the mixture that I'm using in my Blue Clean pressure washer with built-in soap dispenser and nozzle. I diluted quite a bit - maybe 10 to 1 water to soap and it still cleaned up great. Rinse, soap, wipe, rinse. Pretty simple for decent results. Cheaper and better for your car than the carwash... ... show more

    • Not overly harsh or chemical-smelling.
Style: Multi Purpose Cleaner
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. ... show more
