Angelwax Cleanse is a 100g detailing clay bar for removing bonded contamination that washing leaves behind, such as fallout, tar, tree sap, overspray, brake dust and industrial pollution. It is used on a washed and dried vehicle, glided over a lubricated panel until the surface feels smooth, then buffed with a clean microfibre cloth. Angelwax lists it for paintwork, glass, wheels and other exterior hard surfaces, and says it helps waxes, sealants and ceramic coatings bond more effectively. Choose Soft for light contamination and regular use, and Medium or Hard for heavier build-up. Pair it with a dedicated clay lubricant, clean microfibre cloths and a polish, wax or coating to follow.
