Hello Looks like the back pedestal of the Harman P61 left this nasty tiled hearth rust stain! I tried a some household cleaners and Acetone but no luck. Does anyone know if this can be removed? See pic below: Click to Enlarge Thanks Maybe this would work? Soak in lemon juice and salt or axolic acid solution (3 tablespoons oxalic acid to 1 pint warm water). A commercial rust remover may be used. Or Maybe Loctite Naval Jelly Rust remover?
