1. Wash the affected area with a soapy solution to disinfect and remove any dirt.
2. Instead of buying those pricey foams and sprays to keep your appliances looking brand new, erase those smudges with furniture polish. The pre-moistened wipes are your best bet. Just wipe away fingerprints with a little bit of Pledge. The surface usually stays clean for about a week.
3. After you've wiped down surfaces with the polish, try applying a little bit of olive oil with a clean cloth. This adds a nice sheen and actually prevents fingerprints from sticking to the surface.
