450ml Autoglym Alloy Wheel Seal Use Alloy Wheel Seal to discourage build up of unsightly brake dust. Wheels polished with Alloy Wheel Seal are easier to clean and will stay cleaner for longer. If necessary first wash wheels with Autoglym Clean Wheels and allow to dry. Spray wheel rims and spokes with Alloy Wheel Seal and buff surface with dry cotton cloth. Autoglym Perfect Polishing Cloth is ideal. Do not spray through wheels onto brake discs or calipers. If unsure then spray product direct to cloth and apply to wheels to avoid spraying brake components.
