The remnants of burnt food and grime that build up inside your oven can be hard to clean, especially on the glass door, the two sides of which require different treatments.
The inside and the outside of the door don’t have the same kinds of build-up. The glass door will also need a scrub gentler than what you use for your oven’s interior.
The stubborn food stuck inside an oven is essentially acid. It can be neutralized by some dish soap and water mixed with the alkaline and abrasiveness of baking soda.
Spread a paste of baking soda, water, and dish soap on the inside of your glass oven door and let it rest for about 15 minutes before scrubbing the paste using a gentle sponge.
Use paper towels or a microfibre cloth to wipe it off. If the paste doesn’t come off, wipe it away with a cloth dipped into distilled white vinegar and water mixed in a 1:4 ratio.
Alternatively, you can use a degreasing cleaner and a microfibre cloth for the job. If the grease persists, gently use a scraper to scrub it off, trying not to scrape the glass.
As for the door’s outer side, spray on a mix of equal parts vinegar and water, gently scrub it with a non-abrasive or non-scratch sponge, and wipe it with a dry microfibre cloth.
The gap between the outside glass and the inside glass of the door can also collect dirt and grime. Cleaning it requires taking the door off its hinges by following the manual.
Wrap a cloth over a thin cleaning wand to scrub the gap, or use a brush made for such hard-to-reach areas. Note that removing the door yourself may invalidate your oven’s warranty.
