Previous pinner: &quot;The appliance repairman told me using the self-cleaning feature takes years off the life of an oven. The best oven cleaner! Cover bottom of oven with baking soda, then pour vinegar so it&#x27;s all wet. Let sit around 20 minutes or so then wipe all of it out with damp cloth or sponge. I leave my oven door open too. After drying you may see some white residue, wipe again.&quot;
