If you want to take a do-it-yourself route, try Wilkinson's go-to method, which involves dish soap, two microfiber rags, and a round microfiber wax applicator. "Soak the first rag with hot water and add a drop of dish liquid. Dawn Platinum ($4.89, target.com) is the best choice, as it cuts through grease," she says. "Starting at the top of the appliance, go left to right in circles, removing any built-up food, fingerprints, or creams that may have been applied prior." When you're done, she suggests taking the second rag and adding warm water to rinse the solution away. "Then, while the surface is still damp, take the round microfiber wax applicator sponge and—starting at the top—wipe left to right to dry the appliance," she concludes. The secret, she says, is that the sponge absorbs the moisture and then the microfiber cloth buffs the surface, giving your appliance a nice polish.
