The Barrel Boss Mini - wheel brush

The Boss of Tight Spaces.

The Barrel Boss Mini is built for cleaning tight wheel barrels, compact wheels, and small openings where a larger brush won’t fit. Its smaller profile makes it easy to navigate narrow spaces while still delivering effective cleaning power where it counts.

The soft microfiber head safely lifts brake dust and grime without scratching, giving you confidence when working in tighter, more delicate areas.

If you’re dealing with limited clearance or intricate wheel designs, this is the brush that gets in where others can’t.

Can’t reach tight spots inside your wheels?
Larger brushes can miss the details. The Mini is designed to get into smaller openings and clean areas that usually get skipped.

5. Rinse thoroughly and repeat if necessary.
