They are kind of expensive but getting Zerostat would be good especially if you use vacuum machine to clean.I used 16.5 and that built up static and Zerostat did good job (I do double clean cycle with one pre-clean tube and second round then use LAST LP preservative every 50 plays.But tow clean on new Lp definitely build up static on that first clean and even once through machine or simple brush did it as well).No matter what you use to clean LP's even brush static will build up even removal from paper sleeves (and a bit with rice paper VRP's).Yeah Felt is definitely something to dump sound and hassle wise.Acrylic,cork,vinyl all are better.
