How to Clean Stainless Steel. Over time, the interior and exterior of stainless steel cooking items tends to build up a film that it often seems no amount of scrubbing can remove.
If you've tried boiling and then soaking with baking soda, vinegar, or dish soap to no avail, here are some simple solutions to getting this steely surface clean, once and for all.
First: If you haven't tried popping the cookware into the dishwasher -- now's the time.
The heat and dishwasher detergent often removes that unsightly film.
If washed by hand, rinse well and polish dry at once with a soft dish towel to avoid spots, streaks and that filmy buildup.
Keep in mind that some foods (acidic, salt, milk and milk products) should be immediately washed off the surface or they made cause it to corrode.
Avoid
abrasives
or steel wool - it'll destroy the surface sheen.
Cooked-on food or grease can be removed by gently scrubbing it with a paste of baking soda and water and a soft rag or nylon scrubber.
If all else fails, try a commercial cleaning product.
