Faucets usually require constant maintenance, and cleaning is one of the most important parts of it.
Always use a damp, soft cloth to clean the faucet.
You can also use a mild detergent, as anything else can be harmful to the coating.
Therefore, it is necessary to use proper cleaning methods.
How to Clean a Faucet Properly
Clean the faucet daily with cold water and a soft cloth.
A good cleaning solution would be vinegar, dish soap, and a non-abrasive cleaner. These will help keep the faucet shiny.
For a simple and budget-friendly stain remover, simply mix one part water with two parts baking soda.
Apply the resulting paste to the stain and leave for a few minutes, then wipe. Remove any remaining moisture with a clean cloth.
