Angelwax Blue Rinse is a wax-infused rinse aid used as the last step of the wash, after the car has been washed and rinsed. Diluted up to 5 parts water to 1 part product in a foam lance or sprayer, it is left for a couple of minutes and then rinsed off. Angelwax says it creates an instant hydrophobic layer that makes water sheet rapidly off the panels, reducing drying time and towel contact while helping to reduce water spotting and adding gloss. It is a water-based concentrate developed in Angelwax's UK laboratory, available in 1L and 5L. It suits enthusiasts and professionals who want a quicker, safer dry, followed by a plush drying towel and, if wanted, a spray sealant.
