Quality assured cleaning
Anodized aluminum parts that are slightly polluted can be cleaned with clear water and lightly rubbing. A neutral surfactant (pH 7.0) can be added to the water.
After drying, apply a thin layer of anodizing cleaner with a soft cloth. Then polish with a dry, soft cloth to obtain an even, surface free from streaks.
Do not use any acids or alkalis, abrasives, steel wool or pot cleaners under any circumstances. They destroy the anodized layer.
