Prevent oxidation

I was told that if you put wax on bronze, copper, brass…they
won’t tarnish. What type of wax or product would somebody
suggest for this? I’m specifically concerned about the bronze.
I would greatly appreciated suggestions.

Thank you,

Rebecca.

I use “Renaissance” Micro-crystalline wax polish, but I’m
sure there are cheaper waxes that also work great. Gang?
