How long does it take to deep clean an oven?

A single oven in moderate condition takes roughly 45 minutes of active cleaning time. A double oven takes around 70 minutes and a range cooker can take up to 100 minutes. Heavy grease build-up adds up to 40% more time, while light conditions reduce the time by about 30%.

What products do I need for oven cleaning?

A good oven degreaser is essential. Apply it to all interior surfaces and leave to soak (15-30 minutes for heavy build-up). You will also need a non-scratch scouring pad, microfibre cloths, and a plastic scraper for stubborn deposits. Avoid using wire wool on enamel interiors.

How often should I deep clean my oven?

For regular domestic use, a full deep clean every 3-6 months keeps performance and hygiene at a good level. If you roast frequently or notice smoke when heating, clean sooner. Wiping spills promptly after each use reduces the need for heavy deep cleans.
