Every year millions of people buy oven cleaning spray, put on rubber gloves, and spend a sweaty weekend afternoon tackling their oven. But is DIY cleaning actually effective — and is the cost of professional cleaning really justified?
What DIY Cleaning Can Achieve
Standard oven sprays like Mr Muscle or Oven Pride are effective at removing light grease and surface grime. For a relatively clean oven that gets wiped down regularly, they can produce decent results. The catch: they contain caustic chemicals, require significant dwell time (overnight for best results), and simply can't match the penetrating power of professional dip-tank cleaning on heavy build-up.
The Problem With Baked-On Grease
Once grease has been baked on repeatedly at high temperatures, it becomes carbonised — essentially burned black. This kind of build-up doesn't respond well to spray cleaners. You'll scrub, you'll scratch, and you'll still leave residue. Professional cleaners use a non-caustic dip-tank system where oven components soak in a heated solution that dissolves carbon without damaging surfaces.
Cost Comparison
DIY route: A decent oven cleaner costs £5–£10. Add in the time (2–4 hours for a thorough clean), the physical effort, and the chemical fumes, and it's not as cheap as it looks.
Professional clean: Mobile Oven Clean charges from £50 for a single oven. This includes dismantling the oven, dip-tank cleaning all removable parts, cleaning the cavity, polishing the door glass, and reassembly. Most customers report their oven looks better than it did when new.
The Verdict
For routine maintenance of a lightly used oven, DIY is fine. For anything with significant build-up, a range cooker, a tenancy clean, or simply not wanting to spend your weekend scrubbing — professional cleaning is worth every penny. The results are incomparable and the whole job takes around 2 hours.
