When using Autoglym Perfect polishing Cloth tuck in ends to form a pad and hold in the palm of the hand. This will apply an even pressure over the surface being polished. Change to a clean area of cloth as you move to different sections of the vehicle to avoid smearing dirt from one section to another. Autoglym Perfect Polishing Cloths are hand washable and re-usable, depending on the products used and the degree of soiling.
