Clean a stainless steel balustrade with lukewarm water, a mild detergent and a soft cloth or sponge, then rinse with clean water. Avoid steel wool, metal brushes and abrasive cleaners, which can scratch the surface or leave iron particles that cause discolouration. Cleaning frequency depends on the environment.
In sheltered locations, cleaning when the balustrade looks dirty is often sufficient, while installations near the sea or busy roads may need more frequent washing. Clean brushed steel in the direction of the grain and wipe down visible surfaces afterwards. Small brown spots are often caused by airborne iron particles from the surrounding environment rather than corrosion of the balustrade itself.
