- MAXIMUM GLOSS RETENTION: The W4 Citrus Foam has a non-caustic formula that combines an effective citrus degreaser with a strong foaming agent. This exact combination ensures maximum gloss retention through the excellent lubrication of dirt particles, which in turn minimises the surface abrasion, and maximises gloss retention
- EASY TO APPLY: Shake product well before using this product, and do not apply in direct sunlight, for best results use in a snow foam lance. Decant one inch (2.5cm) of W4 into a foam lance and fill with warm water. Spray onto the lower surfaces of your car and work upwards.
