How often should you clean your oven? A general rule of thumb is to deep clean it every three months. Of course, general cleaning should be done after each use.
First, you want to clean the grates
Remove all of the grates
Fill a large tub or bathtub with hot water and some all-purpose cleaner (let them soak, the longer the better)
Remove grates and scrub off residue
Steam The Inside
Wipe or vacuum any loose debris once grates are removed
Put back bottom grate and place a large metal baking sheet or dish filled with water and a ½ cup of white vinegar
Heat over to 350 degrees and let the water bubble
Once bubbling, turn off over, carefully spray inner surfaces with a cleaner
