Shine Supply The Barrel Boss

The Barrel Boss Pro, The Boss of the Barrel.

The Barrel Boss Pro is your go-to brush for cleaning inside wheel barrels, spokes, and deep wheel areas. Built with a soft microfiber head, it safely lifts brake dust and grime while gliding across the surface without scratching.

The comfortable handle gives you solid control during cleaning, while the built-in rubber guard helps protect your wheels from accidental contact. It’s designed to give you confidence when working in deeper, harder-to-reach areas.

If you’re looking for a safe, effective way to clean the inside of your wheels, this is the one you grab.

Struggling to safely clean inside your wheels?
The barrel is where the worst buildup lives; this brush is built to clean effectively while keeping surfaces protected.

Detailer Tips

Start with the barrel: Clean inner areas first to avoid re-contaminating the face.

Let it glide: The microfiber is designed to clean safely—no need to force pressure.

Protection built in: The rubber guard helps prevent accidental contact with the wheel.

Comfort matters: The handle design helps reduce fatigue during full wheel cleaning.

Keep it wheel-dedicated: Never cross over to paint or interior surfaces.

The Barrel Boss Mini, 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.

Detailer Tips

Built for tight clearance: Perfect for compact wheels and limited barrel space.

Use it where bigger brushes won’t fit: Ideal for small openings and detailed areas.

Let it glide: The microfiber head is designed to clean safely without forcing pressure.

Pair it with a larger brush: Use this alongside a standard barrel brush for full coverage.

Keep it wheel-dedicated: Never cross over to paint or interior surfaces.

The Barrel Boss Flex, The Boss that flexes.

The Barrel Boss Flex is built to reach the areas standard barrel brushes can’t. Its flexible design allows you to navigate around spokes, behind calipers, and into contoured wheel barrels with ease.

The soft microfiber head safely lifts brake dust and grime while adapting to the shape of the wheel, giving you better contact in hard-to-reach areas without risking damage.

If you’re dealing with complex wheel designs or tight angles, this is the brush that gets around it.

Struggling to reach behind spokes or around calipers?
Straight brushes can only go so far. The Flex is designed to bend and adapt so you can clean areas that usually get missed.

Detailer Tips

Use the flexibility: Let the brush bend naturally to follow the shape of the wheel.

Perfect for complex designs: Ideal for wheels with tight spacing, angles, and obstacles.

Reach behind components: Great for cleaning behind calipers and deep inside barrels.

Don’t force it: The flexibility does the work—no need to jam it into tight spots.

Keep it wheel-dedicated: Never cross over to paint or interior surfaces.
