Hi Caryn.
"Stainless steel" is not a single type of metal; it's a generic name for any steel alloy that tends to resist rust. Some of these alloys are carefully designed for use in chemical plants to not rust even when immersed in very powerful corrosives, so there are no promises that you can make an unknown stainless steel alloy rust :-)
But spritzing stainless steel with muriatic acid and allowing it to dry three or four times should work, or spritzing with bleach [adv: bleach/sodium hypochlorite in bulk on eBay or Amazon] (never mix bleach and acid), or with ferric chloride [on eBay or Amazon]. Even scrubbing with 00 steel wool [on eBay or Amazon] will hasten the rusting. Good luck, and be very careful with strong chemicals -- assuring good ventilation and always wearing gloves and goggles (as a minimum).
