Sprinkle salt over the grimy areas, as it’ll help loosen the burnt food or stains. Let that sit for 1 hour, and then remove the paste with a cloth or scraper.
Next, combine vinegar, water and lemon juice in a spray bottle. Coat the oven with the mixture, again avoiding the heated elements. Wipe clean with a cloth.
To clean the racks, use the same baking soda mixture. Let it sit for up to 4 hours, then scrub off with a bristle sponge or hose off outside.
