How Do I Clean Fly Ash From Metal?

Fly ash is common in industrial plants.

Fly ash is residue that is left after coal has been burnt in a boiler to produce electricity, according to the Environmental Protection Agency. The ash closely resembles the color and consistency of fine sawdust as it piles on the boiler room floors. This ash can leave a residue on metal surfaces that you can clean with an abrasive cleaner. Do not use heavily abrasive cleaners on stainless steel surfaces as they will likely cause scratches in the metal.

Things You'll Need

• Broom
• Dustpan
• Baking soda
• Water
• Toothbrush
• Mild liquid dishwashing detergent

Instructions

1. Sweep the fly ash into a dustpan and throw it away. It some cases this is the only step necessary to cleaning fly ash from metal.

2. Add just enough water to 3 tbsp. of baking soda to make a thick paste. The paste should be the same consistency as toothpaste.

3. Apply the paste to the fly ash stain with an old toothbrush. Brush the solution into the stain. You will notice that the baking soda paste will slowly pick up the tan-colored stain.

4. Rinse the area with clear water and dry it completely

5. Mix 1 tsp. of mild liquid dishwashing soap with 1 cup of water if the stain is still visible. Do not proceed if the metal surface if stainless steel as the rough abrasive brush may damage the surface.
