With the arrival of winter, slip prevention becomes relevant. 120 million kgs of road salt are applied to Finland’s road network every year. The effect on the prevention of ice is when the temperature drops close to zero, but above six degrees below zero. In colder weather, the effectiveness of the salt decreases and the water it possibly melts freezes even more slippery.
Road salt is practically sodium chloride, which in high concentrations acidifies water, making it corrosive. The natural oxide protection of aluminum rims counteracts some of the effect, but polished areas are prone to corrosion. Surface scratches and dents on the rim collect moisture, causing discoloration and surface deformation in untreated rims. In order to preserve the original shine, it is recommended to clean the rims 2-4 times a month.
The clear and firm Dura-Bright® layer effectively prevents the effect of road salt and does not allow corrosion that started from scratches to spread below the surface. The rim’s shine should still be maintained by regular washing without oxidizing agents. The permitted pH range for Dura-Bright rims is 2-12.
Remember when washing aluminum rims:
– Let the rim cool down before washing, so that it does not evaporate water from the washing solution.
– Avoid acidic cleaning agents used in washing stations.
– Never wash Dura-Bright rims with hydrofluoric acid. – Do not use abrasive tools or substances.
– Do not repair rims by welding. A rim with a deep crack is only suitable for recycling.
