One of the most value-for-money foams I have tried. Personally, I don't expect the foam to clean the car by itself; I spray it with a pressure washer and wash the car with a soft sponge. It saves me a lot of time from having to spread soap from the bucket and also prepares the surface so the car can be cleaned more easily.
Also, your foam cannon and the pressure washer you use matter, because when I went from a 130bar pressure washer to a 180bar one, I noticed a difference. The same goes for different foam cannons.

With a 1/10 ratio in a foam cannon, it produces very dense foam. Of course, the car will also need to be hand-washed. I believe that hand-washing is always necessary regardless of the product.

Okay with a ratio of 1/4. It also needs to be lathered with a sponge. Don't expect 100% results with just the foam.

Very nice product. It removes dirt without any scrubbing at all. The only thing to be careful about is that it requires very thorough rinsing afterwards.

I would give zero stars if I could. The car hadn't been washed for about a month and had some dirt in the lower areas. Even though it produced thick foam, I left it for about 3 minutes but it didn't clean anything. I grabbed the sponge and in 15 minutes the car was clean. Wasted money, choose something else. The ratio I used was the one suggested by the packaging.

It didn't clean anything. And the car didn't have any serious dirt, just dust that had stuck. After rinsing off the foam, the dust remained. If you don't scrub it, it doesn't work. Foam came out, but it didn't stay on the car for long, it quickly fell off and I didn't see a difference.

Cleans very well with a nice scent, nice thick foam whether in a pressure foam gun or hand wash with large dilutions that make it value for money. What else do you want?

I used it with the CDR.0873-Q foam cannon or Wevora as the stores that sell it call it (https://www.skroutz.gr/s/20707172/CDR-0873-Q-%CE%91%CF%86%CF%81%CE%BF%CF%80%CE%BF%CE%B9%CE%B7%CF%84%CE%AE%CF%82-%CE%A0%CE%BB%CF%85%CF%83%CF%84%CE%B9%CE%BA%CE%BF%CF%8D.html?from=catspan) and with the black and decker pw1300b 100bar pressure washer. The result was excellent, at first it creates a thick foam, not shaving foam, but quite thick, and then it starts to run down, pulling all the dirt from the car. I used a ratio of 100ml product and 400ml water. The foam now also depends on the pressure washer and the foam cannon, meaning a pressure washer with more bar can make an even better foam. Anyway, even with such a small pressure washer, the result was amazing and it is also a value for money foam.

Very good product, it makes perfect foam with my Nilfisk brand foam gun! It's worth every penny and more!
