Any stovetop is subject to accumulating stains if you use it for cooking. White gas stovetops are commonly made of ceramic material that is generally easy to clean. If you have tougher, burned-on stains, however, you need to take special measures to protect your stovetop from scratches while you remove these stubborn stains. You can do this by using inexpensive household products that are effective enough to remove stains and yet gentle enough to protect your stovetop's finish.
Remove the grates covering your burners. Soak them in hot soapy water if they need to be cleaned. Wipe them off later with a wet, soapy sponge or rag.
Fill a spray bottle with white vinegar and use it to spray down the entire stovetop.
Sprinkle baking soda onto stained areas of the stovetop.
Wait 15 minutes as the vinegar and baking soda work to dissolve the stains.
Wet a cleaning sponge with vinegar and use it to wipe the stains off the stove.
Wipe the stovetop down with a damp cloth to remove any lingering residue.
Dry the stovetop with a lint-free cloth.
