A solar oven of off-grid stove is a great resource for cooking, but you need to keep these items clean. This is easy to do with nothing more than baking soda and water. As an added bonus, this mixture is eco-friendly. Simply sprinkle some baking soda all over the bottom of your solar oven. Next, spray water onto the baking soda. Leave this mixture overnight and then use a rag or sponge to scoop everything out before you spray the oven down.
