Kitchen utensil type brushes for getting crap off in the nooks and crannies. Theres all shapes, sizes, and bristle hardness available at places like Dunelm. Ive a variety, including the bottle brush type. Parrafin for crud removal, wash off, then wash with washing up liquid, wash off with hose (not pressure washer). Blow dry everywhere with comp air, when dry spray everywhere but the braking bits etc with ACF50. Relube the chain.
