Koch Chemie Reactive Rust Remover (Rrr) Reviews

Good stuff for removing fallout on surface

Yes definitely unpleasant smell and you can smell during entire car wash process if you applied.
But the result was great I was easily to remove something fallout on the hood safely that fallout from train.
If you doing car wash frequently and love to scrub your car add this process with Rrr would be helpful to keep decontaminated and fresh slick paint surface.

Highly recommend

This product is absolutely magical. Had a detail job where the customer had severe burnt on brake dust/rust on chrome wheels. Sprayed some triple R on it, and within a minute, it was changing color and eating the rust away. After several minutes, agitated with a wheel brush, rinsed, and voila, brake dust/rust was gone!! Amazing stuff.
