Suds.Lab XA Zero-Acid Wheel Cleaner breaks down road grime and brake dust as thoroughly as any acid cleaner without the acid. Safe for most wheel types and chrome rims. Abrasive particles activate on contact to dissolve contaminants with limited scrubbing required. Mix with water and splash on, well take it from here. After long nights of experimentation in our garage-atory, (part garage, part laboratory), we boiled car care down to a science. Through trial and error, we have perfected optimal formulas and solvents that breakdown road contamination at a molecular level, leaving your vehicle clean, protected, and ready for the road ahead. We've done all the research - it's a smooth ride from here.
