What is the best thing to use to prep your calls

[NJstrutter]

Conditioning stone for crystal/glass and green scotch brite for slate. Def going to try chalk.

Scotch brite on glass and slate. If a box call is tuned right, you don't need chalk . I also run a little water down my wingbone before using. The water really brings out the clearness in the call.
