Once you do the above use a marine wax or fabric softener sheet (unscented) to keep food from sticking.
Grandpa use marine wax on the stove top, fridge (the older flat style), sinks and tubs in the house. Quick wipe with a dry paper towel everything was clean again and not slippery. He also used a bit of wax paper to rub on sticky door locks, keys, and screw in light bulbs.
