Velvet Ultra Snow Foam is a thick, pH neutral pre-wash foam designed to sit on the panel and lift surface contaminants before contact washing. The maker states that 25ml is enough for a full 1 litre foam lance mix, that a 500ml bottle provides around 20 washes, and that contaminants lift from the paintwork in around 5 minutes. The formulation is LSP safe, matte safe and vinyl safe, so it should not compromise existing waxes or sealants. It fits at the start of a two bucket wash routine, ahead of a dedicated shampoo, wash mitt and drying towel, and suits anyone who wants a thick, clinging pre-wash foam without a strong alkaline formula.
