One star because everything I have used from Meguiar's is excellent unlike this product. For some reason, it fades the upholstery (cinnamon brown - Audi). Along with the dirt, the brown color of the seat also comes off. Unfortunately, the seat has lost its "vibrancy" - shine after using this product. And the moisturizing cream I apply, remains dull.

It is a good product for the job it claims it can do.
The price is a bit expensive compared to the quantity.
It just requires a lot of patience, a light rubbing for a long time, and piece by piece so as not to forget a part of the living room.
Also, if combined with a not too harsh brush, you will have much better results.
Also, a soft cloth to wipe after rubbing is good for removing the residue from the rubbing.

A product that I don't know if it's worth the money. It didn't leave any residue, I applied it directly on the skin and then wiped it off. It made it shine a little, but I don't know if it provides protection or covers scratches

Very good product! I easily cleaned the leather of my car with a nice scent. It didn't leave any residue. It was used by spraying it on a microfiber towel from Meguiar's and not directly on the leather. I recommend it for amateur use!
