The operation itself is really simple. Cancel transportation lock, rotate spray hose up and off you go. The resulting foam has a firm consistency and really adheres well to the rim. Once applied, it takes slightly in volume, and thus then also comes into finer grooves. After the exposure time (foam discolors and expires), I have the rim then with a normal hose sprayed (rim was mounted, so I avoid the pressure washer for the disc brakes). Without after hand washing because it went not. Part was still a film on the rim, the not departed with spraying (which would surely be even better at high pressure cleaner). The dirt such as brake dust and road grime, was satisfactorily resolved. When tar stains but also came this cleaner to its limits.
This is what such 'a way cleaner without concentrated chemicals, is clear, but the odor of exuding here is more than unpleasant. The Note to actually use the cleaner outdoors only, should be strictly adhered to. What I lack information on the bottle is an indication that the cleaner is to be used only where liquids must be properly contained (eg carwash with separator) and not on the national court, where the funds go directly into the environment.
