1. Begin by wiping down the handrail with a soft, dry cloth to remove any loose dirt or debris.
2. Next, use a mild soap and warm water solution to clean the handrail. Apply the solution with a soft, non-abrasive cloth, making sure to clean with the grain of the metal.
3. For any stubborn stains, use a specialized stainless steel cleaner, following the instructions on the label. Be sure to rinse thoroughly with water and dry with a soft cloth.
4. If there are any scratches on the surface of the handrail, you can use a stainless steel scratch remover to buff them out.
5. Finally, to maintain the shine of the handrail, apply a thin coat of stainless steel polish using a clean, soft cloth, and buff to a shine.

Remember to always test any cleaning solution on a small, inconspicuous area of the handrail before using it on the entire surface to ensure it doesn’t cause any damage or discoloration.
