Luckily, stainless steel responds well to cleaning, never wearing out as long as certain rules are followed.
Routine cleaning can be accomplished by using warm water and a cloth. This is the best option for everyday cleaning of stainless steel. Dry with a towel or cloth to prevent water spots. Wipe in the directions of the polish lines. This option may not do the job, depending on how much build-up has occurred.
Fingerprints are one of the biggest complaints about stainless steel, but can be taken care by using glass cleaner or household ammonia. Rinse thoroughly and towel dry.
