Review on 🧴 P21S Gel Refill 1000ml by David Bott

This is the best spray and dish soap I have ever used. The P21S Wheel Cleaner easily removed some of the heavy brake dust stains on my Brembo calipers that had been dirty for years and had not been removed by several other cleaners I had tried over the years. I use a hand sprayer to apply it to the wheels. Because it's a thicker gel, the sprayer is great for "spitting" the product onto the wheel, but it's too thick to spray well with a sprayer. I use a soft nylon brush to spread the P21S over the wheel. but in this case it should be considered a purge. If you could find a spray gun that sprayed P21S and thus spread it better on the rim, you wouldn't need a brush at all!
