After trying 5 different shampoos, I ended up with this one and I use it exclusively now.

The effectiveness/foam quantity may not be the best (I would rate it 3.5/5), but in my opinion, it leaves the best shine (I give it 5/5) compared to all the other shampoos I've tried, and it lasts quite a long time. If I apply it with my hands, the car shines almost as if I had waxed it.

*With the quantity I use (it plays a role in the result), I can get around 10 washes.
*I use a pressure washer with water beforehand.
*I used the same quantity and pressure washer with the other shampoos I had tried

I used it almost entirely in 3 washes. It doesn't foam, at all. Not at all. To have foam for sure, pour half the bottle. Even so... I didn't see it clean particularly well. As other friends have written, you do a better job with dish detergent. And then pass it with a candle if you want (which anyway you would have passed because the wax it has doesn't even work for cat hair removal).

I was not satisfied at all, it does not lather as soap, while its cleaning action is zero until I add dish liquid at the end and then everything gets cleaned. This is only for washing a dusty car.

Quite a weak cleaner. Being excessively detailed in car washing and having tried various cleaners, I must point out that because this particular product requires a lot of scrubbing to clean, "spider webs" are created on the paint, meaning quite small scratches. Also, it really doesn't foam much and requires more effort to clean the car. The wax doesn't do much either. I believe that even with dish soap, I would have the same mediocre result.

Good product for its price. With the recommended dosage, it doesn't create a rich foam, so you need to use a little more. It removes stains and marks if you let it act for a while and then rinse it off. Leaves a nice shine and a good feeling on the bodywork after washing. It is the fourth product in a row that I have tried for a year, and I can say that it does the job it is supposed to do.

Perhaps the best shampoo for cars and motorcycles! I have been using it for 20 years, it leaves a shine at the end because it has wax, it also doesn't produce too much foam without being a disadvantage, but it protects the colors! I highly recommend it!

Very good cleaning, leaves a nice shine at the end but didn't produce much foam. Overall, I highly recommend it
