I started using GG as I had a horrible static electricity issue with LOUD discharge pops. It is definitely good for eliminating the static charge and the resultant dust collection. I first clean with an RCM and then treat with GG. It does deposit some stuff in the grooves, but this is gone after one playing. IMO, it does not ruin the sound, although I respect the opinions of those who think it does. If I didn't have static issues, I probably would not use it, as I really don't hear any sonic improvement. In any case, it will not harm your records and will be removed by a good cleaning.
