Which option lists acceptable items to clean anodized surfaces?

• A. Steel wool
• B. Aluminum wool and Fiber bristle brush
• C. Brass wire brush
• D. Stainless steel wire brush

Answer: (B)

Cleaning anodized surfaces requires non-damaging agitation—the protective oxide layer must stay intact while you remove dirt. Aluminum wool is soft and compatible with aluminum, so it can scrub without gouging the anodized coating. A fiber bristle brush provides cleaning action without introducing hard, abrasive metal particles that could scratch or embed into the surface.

Hard or metallic tools, such as steel wool, brass wire brushes, or stainless steel wire brushes, can scratch, gouge, or remove the anodized layer or leave metal residues that may cause corrosion. That’s why aluminum wool and a fiber bristle brush are the acceptable combination for cleaning anodized surfaces.
