Hi Tom,

An extremely fine spray of distilled water completely eliminates
the disc static problem (no, I don't get the labels wet), and it is
possible to find perfume spray bottles which are perfect for this
purpose.

There are those of us who believe there are also other advantages
to playing discs wet as (but not shellac!).
