METAL
For our collections we take. calibrated steel and brass. Metal treated with powder coating of brass undergoes an anodizing process, which provides longer protection to these products against corrosion, rust and stains.
Steel and brass must be kept clean for a long service life of the material. For normal cleaning, ph-neutral soap and water applied with a sponge or cloth is enough. This will probably only be needed 1-2 times a year as this material is quite resistant to oxidation and residue retention. After cleaning, steel or brass should be thoroughly washed and dried with a soft cloth to prevent streaking.
