How to Clean a Diamond Plate
Diamond plating is lightweight aluminum sheeting that has a pattern of raised diamond shapes. With a texture designed to provide traction, diamond plating is typically used to line stairs, ramps and the side steps of trucks. Diamond plates are highly durable and long lasting, however they are still subject to wear and tear from foot traffic and weather. Routine and proper cleaning will ensure a diamond plate's long lasting shine.

Clean diamond plates that are in extremely poor repair with phosphoric acid cleaner. Phosphoric acid will dissolve lime, magnesium scales and rust stains. Buy phosphoric acid from an auto shop or from a janitorial supply store. Wear latex gloves and work in a well-ventilated area. Use a spray bottle to spray the phosphoric acid onto the diamond plate. The acid will create a whitish color. Let the spray sit for a few minutes, then scrub the sprayed surface with nylon scouring pads. After scrubbing, rinse the surface thoroughly with water. Work in small sections at a time for large diamond plates. Keep phosphoric acid off of surrounding surfaces. Always rinse spills or splashes with water to neutralize the acid. Do not use phosphoric acid on diamond plates that have a manufacturer clear coat. Use paint polish instead of phosphoric acid if your diamond plate has a clear coat.

Apply aluminum polish to the diamond plate. Buff the polish onto the diamond plate using a wool buff pad. Buff by wiping in overlapping, circular motions or use a hand-held orbital polisher with a soft pad.
