Yes, normally you should always wrap your handholds with one layer of a plain, white paper towel. Don’t wrap multiple layers of the paper towel around the handholds because it will act more as an insulator, keeping the current from the handholds from getting to the skin.
Always keep the paper towel moist. It doesn’t have to be dripping wet, but if it dries out even one layer will act as an insulator, reducing the effectiveness drastically.
