If you’ve ever seen a car with baked on brake dust you’ll know how unsightly it becomes as the layers of dust build up over time. Not only can brake dust become corrosive if left unattended, but when you do finally clean the brake dust away you can scratch the surface of your rims and even your paintwork by moving the brake dust around if you’re not using the right cleaning products.
Why You Must Remove Brake Dust Safely
Brake dust is more than just dirt; it contains metallic particles that develop a static charge and adhere to your rims. If left to build up, the metallic dust becomes corrosive and can eventually embed itself into the surface of the rim’s clear coat—making complete removal impossible. Improper cleaning can also drag the sharp dust particles across the surface, causing scratches on your rims and paintwork.
Step-by-Step: How to Prevent Brake Dust Build-Up (Regular Washing)
The most effective way to manage brake dust is to prevent the heavy build-up in the first place.
WASHING ON THE REGULAR
The Weekly Wash Routine
- Rinse Thoroughly: Use a hose or pressure washer to knock off the loose dust and cool the wheels. Crucially, never clean hot wheels.
- Use Neutral Soap: Apply a neutral soap or dedicated wheel shampoo to ensure lubrication and prevent chemical damage to your clear coat.
- Dedicated Tools: Use a separate sponge, brush, or wash mitt for your wheels. This prevents metallic brake dust particles from transferring to your car’s paintwork and creating unsightly swirl marks or scratches.
- Agitate and Rinse: Scrub the face and inner barrel of the wheel, then rinse thoroughly.
- Sealant Application: For long-term protection, apply a wheel sealant or ceramic coating after a deep clean to create a barrier that repels dust and makes future washing easier.
How To Tackle Heavy, Baked-On Brake Dust (Deep Cleaning)
When regular washing is no longer enough, you need stronger products. This process is more intensive and requires caution.
The Safe DIY Method (Iron Decontaminator)
- Pre-Rinse and Spray: Rinse the cool wheel and apply an iron decontaminator spray (these are typically balanced/neutral).
- Wait for the Reaction: These products are specially formulated to dissolve the metallic iron particles. The spray will turn a deep purple or red (“bleeding”) as it reacts with and dissolves the brake dust.
- Agitate (Gently): After the prescribed dwell time (check the product label), use a soft-bristle brush, wheel woolie, or specialized barrel brush to gently agitate the cleaner on the surface and in hard-to-reach areas.
- Rinse Heavily: Rinse the wheel completely, ensuring no residue is left to dry.
The Warning on Acidic Cleaners ( Negative)
Many heavy-duty wheel cleaners on the market are acid-based ( negative). While highly effective, they are also highly corrosive and pose a risk of:
- Damaging clear coats, polished metals, and surrounding paint if left on too long.
- Safety Hazards: Risk of inhalation, skin burns, and environmental damage when run-off enters stormwater.
- Our recommendation is to avoid acid-based products unless you are a trained professional.
