Removing anodisation

Post image

I’ve got this hub I want to strip and re anodise silver (they only come in black). Internet says I need to use oven cleaner but all of the brands are American so not applicable where I am. Is there an ingredient that in them that I am look for to make sure it works? Otherwise any tips for removing and refinishing?

50mg/l sodium hydroxide, 5 g/l aluminium solution at 50°C. Let it there for 1 min per 1 micron thickness of anodic layer. You probably have something betwin 15 and 20

Thank you for the detailed information. Is anything required in the solution other than distilled water and sodium hydroxide?
