I’ve already shown you how to clean your oven with a mix of baking soda and vinegar. And now, we’re going to tackle those oven racks and rid them of any grime so that they don’t mar your newly cleaned oven. It’s easy to do, and a project you can take on right alongside your oven cleaning!
If you have a bathtub and dishwasher detergent, you are set. The hardest part about this process is the inactive time, but it’s worth it: The soaking of the racks aids in softening up the accumulated gunk, making it easier to wipe and gently scrub off. I barely had to use any force, and my racks are now cleaner than they have been in years.
