Recommendation: SONAX recommends XTREME Wheel cleaner full effect. It is a powerful, acid-free special cleaner for all steel and light-alloy rims and wheel caps. It easily removes even stubborn dirt such as baked on brake dust, oils and rubber residues, and other street dirt from all steel and light-alloy wheel rims and trims. Aggressive cleaners can cause corrosion on wheel bolts and metallic areas round the rim. The new SONAX XTREME Wheel rim coating Nano Pro is the ideal sealing. It protects the rim by forming a transparent and hard nanolayer that becomes extremely dense, compact and smooth within a short time. Thus, the surface simply repels water, salt and dirt. The ultra-thin, durable sealing reduces resoiling and the adhesion of dirt and brake dust on the treated surfaces. This significantly facilitates the cleaning of rims. At the same time, the sealing produces a long-lasting and brilliant shine. The lotus effect lasts for at least five washes. The contents last for up to eight rims (light-alloy, steel, and also chrome plated rims).
