Save money by cleaning??? Crazy, I know. However, cleaning your oven regularly can save you from a fire and can keep you from spending an inordinate amount of time deep cleaning once it gets really bad. If you have a self cleaning oven, then the process of cleaning is simple enough. If you do not have that option on your oven, then you may have to resort to old fashioned methods. You can find multiple methods of cleaning your oven. One of the cheapest, most environmentally friendly methods is to use baking soda and vinegar and a whole lot of elbow grease, a grill scrubbing brush works well. You can spend more and pick up a can oven cleaner and open your windows.
