What does "PLUS" mean? Let's put it this way... It's bad news for brake dust. In literal terms, it's 20% stronger than the previous formula without risking damage to most wheel finishes. Despite its brute power, it's pH-neutral and remains acid-free.

Its little brother, Sonax Wheel Cleaner Full Effect has been a long-time staple in many detailers' arsenals simply because it works well and remains relatively cost-effective in doing so.

Wheel Cleaner PLUS takes it to the next level; it works more quickly and thoroughly against large buildups of brake dust. If Wheel Cleaner Full Effect is a Porsche 911 Turbo, this is the 911 Turbo S. The same formula, but turned up for those who desire extra power and efficiency.

If your car (or your customers' cars) make blasphemous amounts of brake dust, Sonax Wheel Cleaner PLUS is an extra-powerful weapon against those stubborn embedded iron particles. Simply spray it on wheels that are cool to the touch, allow it to dwell for 2-4 minutes, and rinse it off. This wheel cleaner leaves the bottle in a fluorescent green color to help locate where product has been applied, and turns a deep plum color as it reacts with and releases iron particles.
