Kitchen accidents happen. Whether it's the occasional boil-over or a big spill, your electric stove top is bound to get a little gunked up after a while. When a simple wiping won't do, turn to the do-anything household multitasker: baking soda.
Apartment Therapy notes that you can often just turn the hot plates on high to burn off any caked-on food, but if they need a deeper clean, baking soda is the answer. Let them cool completely, then remove them from the stovetop (if removable) and clean them with a paste of baking soda and water. For really stubborn stains, let it sit for 20 minutes before rinsing it off with a damp rag (be careful of the electrical connections, though!).
