First of all, this soap does not lather at all and is not meant to clean a heavily dirty car. It also has a banana scent.

As the title suggests, it is meant for quick washing, meaning if you have already washed your car and applied wax/resin/ceramic and there is dust, a little dirt, grime, pollutants from exhaust fumes, brake dust, etc.

If there are stubborn stains, especially insect stains or resin, then it becomes quite difficult. I tried it on two cars, the small one was "clean" and it washed it quickly, but the professional one, which was a bit dirtier, had some difficulty, especially on the mask with the insects. It took 3-4 passes. On the small car, it polished it and left an extra film on top of the wax and windows, which seems to keep dust and water away and also left a soft touch. It cleaned the professional car, but with somewhat satisfactory results.

It is not a bad product at all, it does what it says. It is just intended for car enthusiasts. Meaning, for those who have the "hard" soap for deep cleaning or pre-waxing, the soap with wax for wax maintenance, and this one here for maintenance of the maintenance.

As a product, it is very good, I would buy it again. I just don't think it's suitable for everyone. For the average user, the Pure Shampoo alone or in combination with the Shampoo Conditioner is sufficient.
