Yes,stainless steel appliances are so pretty. But they point to every single fingerprint and smear of food that lingers on your fingers. Instead of wiping every day with harsh cleaners, we've discovered a two-step method that's seriously cheap and natural.
Generously spritz the appliance with distilled white vinegar and wipe clean with a soft cotton cloth, and working with the grain of the appliance. Vinegar busts trough stuck-on gunk while naturally cleaning and disinfecting. Let the appliance dry for 20 minutes.
Give things a rub-down with a clean soft cotton cloth and olive oil. Once again,work with the grain of the appliance and don't be stingy with the oil! Use a clean cloth for a final polish and your appliance is clean and shiny! The olive oil creates a semi-protective layer that will serve reduce the amount of oil marks left from your hands.
