Yes, you can remove Road Force Measurement System (RFMS) marks from your tires while they are still mounted on the car. It's a straightforward cleaning task, but the key is using the right products and techniques to avoid damaging the tire's rubber or the wheel itself. The white or yellow chalky marks left by the RFMS machine are meant to be temporary and indicate where the technician balanced the tire and wheel assembly.
Safety is the absolute first step. Ensure the car is parked on a level surface, the parking brake is firmly engaged, and the vehicle is in "Park" (for automatics) or in gear (for manuals). Allow the wheels and brakes to cool completely if you've been driving recently to avoid burns.
For cleaning, you'll need a dedicated tire cleaner or a mild all-purpose cleaner. Avoid harsh chemicals like brake cleaner, gasoline, or strong solvents, as these can break down the rubber compounds over time, leading to premature drying and cracking. A soft-bristled brush, like a detailing brush or an old toothbrush, and a microfiber towel are ideal tools.
Spray the cleaner directly onto the RFMS marks and let it sit for 30-60 seconds to loosen the material. Gently agitate the area with the soft brush, then wipe it away with the microfiber towel. For stubborn marks, you may need to repeat the process. Once the marks are gone, you can apply a protectant like a tire shine product to keep the sidewall looking new.
| Recommended Products for RFMS Mark Removal | Type | Key Benefit | Caution |
|---|
| Dedicated Tire Cleaner | Specialty Chemical | Formulated to be safe on rubber | Avoid gel types that are too thick |
| Isopropyl Alcohol (Diluted) | Solvent | Effective on stubborn residues | Test on a small area first; can dry rubber |
| Mild All-Purpose Cleaner | General Cleaner | Readily available and inexpensive | Ensure it is rubber-safe |
| Car Wash Soap | Detergent | Very gentle and safe | May require more scrubbing effort |
| Water-Based Detail Spray | Lubricant/Cleaner | Safe for all surfaces | Least aggressive option |
While this is a simple DIY job, if the marks are excessively stubborn or you are not comfortable, a quick visit to a professional detailer is a safe and effective alternative.
