Angelwax Cleanliness is a concentrated citrus pre-wash for breaking down heavy contamination before the contact wash. Angelwax formulated it to remove bugs, road grime, bird droppings and traffic film, and the water-based, solvent-free formula is safe for waxes, sealants and ceramic coatings, so it suits protected cars as well as neglected ones. Dilute 1:1 for heavy contamination or up to 5:1 for maintenance washes, apply by foam lance or pump sprayer, leave it to dwell for several minutes without drying, then rinse. Removing grit before a mitt touches the paint helps reduce swirl marks. Follow it with a shampoo wash using the two-bucket method, and flush the lance afterwards. Available in 1L and 5L.
