How to Clean Burnt Grease from Your Oven

Burnt grease is one of the most stubborn and common problems in any oven. It builds up over time from spills, splashes, and repeated cooking — and if left untreated, causes smoke, bad smells, and affects cooking performance.

For light grease, a paste made from baking soda and water applied to interior surfaces and left for 30 minutes before scrubbing with a non-abrasive cloth is an effective starting point. This is safe, cheap, and surprisingly effective for fresh or light build-up.

For heavier deposits, specialist oven degreasers provide better results. These break down carbon and grease more effectively — but always ensure thorough rinsing to remove all residue before cooking.

Soaking removable parts such as racks and trays in hot soapy water can significantly improve results on those components. Overnight soaking works particularly well for heavily soiled racks.

However, DIY cleaning has its limits. Deep carbon deposits that have built up over months or years often cannot be fully removed without professional equipment and specialist solutions — this is where professional cleaning delivers a far superior result.
