Brushed or powder-coated aluminum is an easily cleaned material, making care as easy as rubbing it down with a damp cotton cloth. Rubbing down with a dry cloth after cleaning prevents water marks from forming. Do not use abrasives or steel wool!
Dust or dirty marks can be removed with a dry cloth. More stubborn marks can be removed with a gentle cleaner, taking care to dry the surface completely after cleaning to avoid leaving water marks. Do not use harsh cleaners or shoe polish.
