Anyone have a way to chemically clean white corrosion from zinc pot

but I really will not be happy until I get the body looking as good as
I can before I reassemble it. Tried, CLR, Ospho, Muriatic along with
carb soak. The corrosion is all that is left on the body now. Ideas
anyone?

This is a carburator so there is no way a cup brush could be used on/
in it without destroying something

Then go to a welding store and purchase a stainless steel
"toothbrush". They're used for welding aluminum, cost a buck or so.
