Review on 🧴 P21S Gel Refill 1000ml by Mark Loredo

Best rim cleaner I have found in the last 20 years. However, note that this is the GEL version. The normal version is ok. You're probably better off getting the Griot version than the regular P21S. Lari costs more money but it's worth it. I did a test spraying one half of the wheel with it and the other half with Griot (or non-GEL P21S). Without cleaning, the side with gel is better cleaned with a hose after washing the wheels. If you wash your wheels often enough, you will have to clean your wheels significantly less with GEL cleaner. Cleaning is mandatory for Griot and P21S without GEL.
