Isn't it always the way - when you no longer need it, something that was hard to get becomes commonly available?

Allbrite was fantastic for cleaning the old cast alloy VB/VC SL/E rims (15" versions of the HZ SL/E 14" rim). It used to be real hard to get back in the 90s - I sourced it from a commercial cleaning supplies place.
I agree with Adam - it worked well on wheels (didn't pit the machined rim surface), so it should do well on tags.

Same stuff I told you about on Saturday Blocker. If you want a test tag let me know I will post you one to play with.

Bought some and tried it out. It worked well so thank you for the tip, much appreciated.

good stuff. It leaved allu quite dull. So use a prepsol or simular after and it will brighten it up.
