Brake dust, tar, and road film are some of the toughest contaminants to remove from RV wheels. If left untreated, they can etch into clear coat, dull your rims, and ruin the shine of your entire rig. In this step-by-step guide, you’ll learn how to safely and effectively remove brake dust and grime using the right tools and products — without damaging your RV’s finish.

Why Brake Dust Is a Problem for RV Wheels
Unlike cars, RVs carry a lot more weight — which means more braking force, higher temperatures, and more brake dust. Over time, this dust bonds with road film and moisture, creating a stubborn, corrosive layer that eats into wheel finishes and coatings.
The key to cleaning it safely is using a pH-balanced cleaner strong enough to dissolve grime, but gentle enough to protect coatings and rubber.
What You’ll Need
- Pure Magic Cleaner – acid-based cleaner that melts away brake dust and iron deposits.
- All Dressed Up – to protect and finish your tires after cleaning.
- All Blacked Out Applicators – for tire dressing.
- Soft wheel brush, barrel brush, and detail brush set.
- Pressure washer or strong hose.
- Microfiber towels for drying.
Step-by-Step: How to Remove Brake Dust and Road Film
Step 1: Rinse Thoroughly
Start by rinsing your RV wheels with water to remove loose debris. Use a pressure washer if available — this helps flush out trapped dirt and prevents scratching during the cleaning process.
Step 2: Apply Pure Magic Cleaner
Spray Pure Magic Cleaner evenly onto the wheel face, barrel, and tire. Allow it to dwell for 30–60 seconds. You’ll see brake dust begin to dissolve and the cleaner slightly change color as it reacts with iron deposits.
Do not let the cleaner dry on the surface, especially in hot weather or direct sunlight.

Use a long-reach brush to clean inside wheel barrels and a soft detail brush for faces and lug nuts. Scrub gently in circular motions to loosen stubborn grime. For the tire sidewall, use a stiff nylon tire brush to remove browning and old dressing residue.
Step 4: Rinse Completely
Rinse the wheels thoroughly until the water runs clear. Pay attention to hidden areas like lug holes, behind spokes, and brake calipers where residue can linger.
Step 5: Dry the Wheels
Use a dedicated microfiber towel or compressed air to dry the wheels. Drying helps prevent water spots and allows protection products to bond better.
Step 6: Dress the Tires
Once the wheels are clean and dry, apply All Dressed Up to the tires using an All Blacked Out Applicator. Choose your preferred finish — wipe off after 5 minutes for a matte look or leave on for a glossier shine.
