anti slip for turntable belt


Have you tried a safe product  that can extend the life of a turntable belt, and help also the belt not to slip at departure of the platter ?

Agree with @invictus005 -- back when I had an Orbe you'd take the belt and put it in a baggie with talc and give it a shake -- bingo

My current deck has a geared belt so no such issues
Do Not use Armor All, it has silicone and will cause slippage.
Remove the belt, use an alcohol wipe and gently clean it. After it dries put a small amount of talcum powder in a baggie with the belt. Toss it gently to coat the belt, remove and shake off excess. Clean the outside edge of the platter where the belt rides with an appropriate cleaner and dry. Install the belt. If the belt is stretched, drop it in boiling water for a couple seconds before the talcum treatment.
