How to make a blue bezel silver

Some lights e.g. Olight have blue stainless steel bezels. I don’t know if they are blued with heat or chemicals. Can they easily be returned back to the bare metal ? Polishing is out of the question due to intricate details. Acids would be my guess.

Never handled one so unsure, are they definitely stainless steel? If they are aluminium and it’s just anodising, that’s easy to remove with caustic substance, plenty of threads on this forum about stripping anodising.

Yes I’ve stripped anodised aluminium cookware, accidentally, using NaOH. Skilhunt blue bezels are stainless steel.
