What are the best cleaning agents for stainless steel outdoor chairs with stubborn stains?

Stainless steel outdoor chairs are durable and stylish, but stubborn stains can dull their appearance over time. To restore their shine, use specialized cleaning agents like vinegar and water solutions, baking soda paste, or commercial stainless steel cleaners. For tough stains, a mixture of mild dish soap and warm water works well. Avoid abrasive tools like steel wool, as they can scratch the surface. Regular maintenance with a microfiber cloth and protective coatings can prevent future stains and keep your chairs looking new. Always rinse thoroughly and dry to prevent water spots.
