Hi MamaG, Thank you for your question. The corner shelf of the model 41416 is non metallic, the bar portion is stainless steel. Always blot dry any water from faucet surface. Allowing water to evaporate on the surface can lead to build up of mineral deposits. Cleaning with a damp non-abrasive sponge and buffing it dry with a clean soft cloth should help keep your product looking beautiful. To remove water spots, use warm water and a soft, damp cloth. Hard water stains may be removed using a 50/50 solution of white vinegar and water. Make certain that you rinse thoroughly with water afterward.
If additional cleaning is required, all of our finishes may be cleaned with the following household cleaners: Formula 409® Antibacterial All Purpose Cleaner, Fantastik® All Purpose Cleaner, or Windex® Original Glass Cleaner, when used according to the manufacturers' instructions for use.
Avoid using the following which can damage your finish:
Avoid industrial cleaners and abrasive cleaners, such as those used for toilet bowls, green Scotch-Brite heavy duty scrub sponges, Scrubbing Bubbles Bathroom Cleaner and Lysol Basin Tub, Soft Scrub, and Tile Cleaner.
Avoid products that state on the label that they remove tarnish and rust, and those containing hydrofluoric, hydrochloric and/or phosphoric acids and caustic agents.
Avoid harsh abrasives or polishes
Avoid bleach-based cleaners
