When asked what would assist cleaning carbon & oil build from staionless steel heat exchanger plates, we immediately turned to U Beaut. We demonstrated the product along side their existing method, which was to spray the product onto the soiled surface and leave for 20 minutes. After that the surface was pressure sprayed to remove the contaminant. In this trial, U Beaut achieve a better clean, and also took 3.5 minutes less to clean – when you clean a couple of hundred at a time, this was a massive saving. After the trial we recommending using the U Beaut in a bath situation with some aeration for agitation – this saved more time, but also got an even better finish.
