Titanium anodic coating on anodizing racks




Does the purple-blue anodic coating on Titanium inhibit conductivity? Do I need to remove this from racks used for Hard Anodising in 15%sulfuric acid? If so, is there an effective method available to achieve this?

I am very new to anodising and would greatly appreciate any help.

The thin oxide coating which forms on titanium racks does no harm and does not need to be removed.
