Why it happens
Every time something bubbles over, the heat bakes it on. Next time, it bakes on a little harder. After enough meals, it's a crust that won't wipe off. Baking soda softens that crust slowly, so you don't need to scrub as hard.
Edie's tipPut a sheet pan on the rack below anything that might bubble over.
What not to do
- Using oven cleaner in a self-cleaning oven
Many manufacturers warn against it because it can damage the coating. Check your manual first.
- Leaving racks in for self-clean
The heat can discolor racks and make them hard to slide, unless your manual says they can stay in.
- Getting paste on the elements
Paste on heating elements or gas openings can smoke or clog them.
- Scrubbing with steel wool
It can scratch the enamel inside the oven. A plastic scraper is gentler.
When to call a pro
Call an appliance pro if the oven door glass is cracked, the door won't unlock after a self-clean, or the oven stops heating evenly. A professional cleaning service is an option for very heavy buildup.
Questions
Is the self-cleaning cycle safe?
It's made for the job, but it gets very hot and can smoke. Open windows, take the racks out unless your manual says otherwise, and don't leave home while it runs.
I have pet birds. Does that matter?
Yes. Fumes from a self-cleaning cycle can harm or kill pet birds. Move them well away, or out of the home, before you run one. The baking soda method is a safer pick.
How long does a self-cleaning cycle take?
Often 2 to 4 hours, plus cooling time. The door stays locked until it cools.
Can I clean the glass on the door?
Yes. The same baking soda paste works on the inside glass. Wipe it off with a damp cloth.
