There’s a reason anodizing is never explained in detail here… this isn’t an anodizing forum full of adults, it’s a YoYo board full of kids.
The process deals with nasty chemicals and electricity, it can be very dangerous is not done properly… that is not the kind of stuff we need.
Do I think most kids are going to even attempt it? No, but it just takes one idiot with an incomplete understanding to get hurt by something they read here.
Simply put, this isn’t the appropriate place for the discussion. The internet is huge, this information can be found elsewhere by those looking seriously for it.
