7. Let the Paste Work: The Waiting Game
Patience becomes your best friend in this low-cost oven cleaning technique once you have the cleaning substance applied. The miracle of the baking soda on the tough grease and filth takes time. For optimal effects, leave the paste on for at least 12 hours—or preferably overnight. The baking soda’s alkaline qualities will gradually dissolve the gathered grime, grease, and food bits during this period. Particularly on really dirty ovens, the paste will be more effective the longer you can leave it. Should your oven be just mildly dirty, you might be able to get away with a six to eight hour waiting time. On ovens with tenacious baked-on filth or those that haven’t been cleaned in some time, however, a full 12 hours or more will produce the finest results. Resist the need to routinely check on the development by opening the oven door while waiting. Opening the door runs the danger of drying out the paste, so lessening its efficacy. If you haven’t already, instead spend this time cleaning the oven racks. You may apply the same baking soda paste to them or soak them in warm, soapy water. Although the waiting period seems lengthy, it is an essential phase in this process and the reason this approach is so successful without using strong chemicals.
