Yes, the Norwex descaler is safe to use on stainless steel surfaces. The descaler is specially designed by Norwex to remove lime scale deposits and hard water stains from numerous household surfaces including stainless steel fixtures such as sinks or appliances like stovetops or refrigerator doors. When using the descaler on stainless steel, it is recommended to dilute it with water according to the instructions provided on the bottle. It's important to follow these instructions carefully and avoid leaving the descaler on the surface for an extended period of time as it could potentially damage or discolor stainless steel if not rinsed off properly.
