Is the metallic finish of the brush handles rust-resistant?

Our Artis brushes have a protective finish built into a layer of the handle, so under normal conditions it should not be affected by fingerprints, cleaning, pigments or rust. To keep our brush handles clean and sanitized, simply use a small amount of our Foaming Brush Cleanser and the supplied microfibre cloth to wipe all surfaces of the handle. Finish by wiping the handle with a slightly damp cloth.
