Try Sprayway stainless cleaner. Comes in a spray can. Usually found at Wal-Mart.
Hi Melissa, hopefully one of these suggestions will help. https://www.wikihow.com/Clean-Grease-Off-Stainless-Steel
I use a sponge and Dawn dish detergent.
Hi Melissa: Apply white vinegar directly to a microfiber cloth, or spray directly onto your surface. Let sit for just a moment, and then wipe clean in the direction of the grain. Apply the vinegar as many times as necessary to remove any grime.
Or, you can clean grease off stainless steel by first washing with soap and water, scrub with a nylon brush along the steel's grain, then apply baking soda and vinegar for the toughest stains, and finally rinse off any cleaner and dry the steel to prevent water stains.
Be sure to always go with the grain of the steel.
