Cleaning metal

[Joe & Penny Goss]

Hi John, If you have a music store with a band instrument repair
department, they should have a product called Exo Kleen ( I think that is
the name ) used to clean out metal instruments or mouthpieces. Just a 10
minute soak will loosen up most grunge so that it can be rinsed out. Or
Lime Away, is a product readily available from most grocery stores, should
work.
