Surface Preparation

Surface Preparation

Surface preparation prior to anodizing is critical in achieving the best anodizing results.

Polishing Tip

Surface cleanliness and preparation is the key to good polishing results. Attempting to polish a dirty surface or one that has not been properly cleaned using proper industrial grade cleaners will only result in the impurities being forced deeper into the surface.


Manual and/or mechanical polishing provides a lustrous surface finish to improve the appearance of any part.

Some choose not to further process their parts after polishing while most will specify an additional process such as anodizing. The result is a very high end and unique finish that stands out from traditional anodized and plated parts.
