Chemical Guys HydroSuds Ceramic Car Wash Soap is infused with nano SiO2 that ensures your paintwork receives ceramic protection from suds that leave an incredible gloss. Offering a good level of protection, Hydrosuds leaves a silica-rich film behind that helps repel water, dirt, and other pollutants, keeping your car cleaner longer. Use Hydrosuds on a non-coated car to add a hydrophobic layer, or revitalise already ceramic coated cars with a simple wash and rinse.
