The Angelwax Brush-Up set brings together five pure bristle detailing brushes in sizes 10, 12, 14, 16 and 18. Angelwax designed it for the intricate areas a wash mitt or cloth cannot reach: badges, grilles, emblems, panel gaps, air vents, switches and interior trim, as well as wheel nuts, brake calipers, engine bays and shuts. The bristles are soft, so the set suits enthusiasts and professionals working on delicate interior plastics as well as exterior details. We suggest reserving one or two brushes for wheels and engine bays and keeping the rest for interiors. Pair the set with an interior cleaner, an all purpose cleaner or a wheel cleaner, and clean microfibre towels to wipe away what the bristles loosen.
