Autoglym Polar Wash is a pH-neutral snow foam car shampoo designed for use with pressure washers. It creates a thick, high-cling foam that safely encapsulates and removes dirt, traffic film, and road grime from your vehicle without harming paint, trim, wheels, or tyres. This formula is streak-free and won't strip existing waxes or sealants, making it ideal for a thorough pre-wash or touchless clean on lightly soiled cars. For best results, follow with Autoglym Polar Seal for a durable hydrophobic coating.
