I bought it for cleaning our Weinor awning, which has a housing made of aluminum. It is a recommendation of the awning manufacturer. The cleaner is but suitable for many and is highly recommended. Our canopy plastic had the dirt, did not go away by wiping, with different cleaners. The cleaner everything white again. Our white metal fence with plastic coating is white again. Contamination by rain UDN environmental dirt came off all. Just spray and wipe with a cloth again, without exposure.
