DIY oven cleaner
Sponge or scrub brush
Distilled white vinegar
Start with a cold oven. Create cleaning paste by mixing baking soda, coarse salt and dish soap. Should have similar texture to frosting and be thick enough to cover walls without it dripping. Spread the paste and leave for a couple of hours or overnight if possible. Wipe away mixture with damp sponge. Once most of the paste has been removed spray inside with vinegar spray (one part vinegar, one part water).
