Which type of brush is approved for cleaning corroded anodized surfaces?

Fiber bristle brushes are specifically designed for cleaning sensitive surfaces, such as anodized aluminum, because they do not scratch or damage the protective anodized layer. Anodized surfaces are treated to resist corrosion and wear, and using a gentler cleaning method helps maintain the integrity of this protective coating.

Unlike steel wire brushes or metal scrubbing pads, which can be too abrasive and may strip the anodized layer, fiber bristle brushes provide a safer option for removing surface contaminants like corrosion while being less likely to cause harm. Plastic bristle brushes can also be used for cleaning, but they may not be as effective in removing stubborn corrosion compared to fiber bristles, which can offer a better balance of cleaning capability without damaging the anodization. Thus, fiber bristle brushes are the approved and preferred choice for this application.
