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 Ultra-Fine for light contamination and regular use, and Medium or Aggressive for heavier build-up. Pair it with a dedicated clay lubricant, clean microfibre cloths and a polish, wax or coating to follow.
