I guess I should expound on that a little and make an article out of that sentence, somehow. On electric stoves the wires often run under the drip pans and often when drip pans get really dirty, people just throw them out and do without.
Wires get crisp, the insulation breaks, and shorts occur.
Spills, both on top and inside the oven clean easily, if they don't bake on forever. For all oven, or heavy top surface cleaning, other than aluminum surfaces which will be stained by this product, use a janitorial supply non-aerosol oven and grille cleaner, with gloves. It is much cheaper and less fuming than the aerosol from the supermarket. Installing new drip pans for burner top areas occasionally will save you from hours of scrubbing, but in between not letting them get really bad is best. This is very caustic, so use great caution and never get on your skin.
