Yamaha C7

[Richard Brekne]

Hi David. I suppose protek should work pretty good. I have heard of just
about everything from vaseline to talcum powder. Personally I find that
cleaning the spring with a polishing agent.. like Color back from
Simonize lasts longer then anything else I have tried. But sooner or
later they are going to need cleaning again anyways. If there is a felt
glued in the groove I give it a dab of teflon powder
