Acid containing wheel cleaners can induce corrosion on wheel bolts and metal parts like the brake calipers. For this reason an acid free cleaner is strongly recommended: Very good results can also be achieved without aggressive acids, this was proved by the SONAX XTREME Wheel cleaner full effect, winner of a comparison test by AUTO BILD SPORTSCARS (10/2012) The test winning formula is now also available in a practical 400 ml spray can.
Incidentally, the cleaning can be greatly simplified through regular application of the SONAX XTREME Wheel rim coating. The spray is very easy to apply – and it will protect painted alloy wheels, stainless steel wheels, chromed and polished surfaces. After thorough cleaning the wheel rim sealant is sprayed on and evenly distributed with a polishing cloth. The sealant combines with the wheel rim surface within an hour. The result is a high gloss, transparent protective coating that is as hard as glass, and it lasts for weeks. Dirty water just runs off and the typical soiling is much easier to remove.
