As the product I usually buy was out of stock and it is quite good, the shopkeeper suggested this specific product to me. It is the worst thing I have ever used for washing my car. I bought it to use it in a foam cannon (after I had tried it earlier in a plain bucket of water) and the result was that it left all the dirt on the car. Without even adding water to the foam cannon the second time because the dirt wouldn't come off, it still produced just a watery foam. A product from a company that even its own mother doesn't know would do a better job than Karcher's product.
