To get the best results from the natural oven cleaning recipe you choose below, allow the mixture to settle in the oven for about 15 to 30 minutes (depending upon the level of grime in the oven) before wiping it out.
If using a baking soda-based natural cleaning recipe, I recommend scooping out a bit of the baking soda first, after it has had time to settle, but before scrubbing in a circular motion.
Spraying the oven with distilled white vinegar after completing the cleaning step will bring up any baking soda that is left inside and help remove any last bit of baked on, caked on, grime that still remains without the need of more intensive scrubbing.
You can, however, safely use a hydrogen peroxide based recipe and AFTER it has been wiped clean, go over it with distilled white vinegar to add even more deep cleaning or a streak free rinse and shine to the oven or other cleaning surfaces.
