It's true: Most of the time, stainless steel will come clean with warm water, with or without a gentle detergent. Simply rinse your stainless steel pots or cutlery in the sink and clean them with a gentle cloth. If you'd like, add a little of your favorite household detergent to make the job easier.
Sometimes water may contain mineral solids that can leave water spots on stainless steel, so wipe thoroughly with dry towels to keep your pots and pans or appliances looking their best.
Be sure to use this cleaning method first before you move on to other solutions. You may find a little warm water and suds will do the trick, and you don't need to bother with harsher cleaning solutions.
