Can a Plant-Based Oven Cleaner Really Compete?
When it comes to everyday grease and grime, most people reach for whatever gets the job done fast. But with eco-friendly alternatives gaining popularity, it’s worth asking: can they actually match the performance of mainstream degreasers?
In this comparison, we’re putting our highest-rated eco spray and highest-rated regular spray from our Top 10 Everyday Oven Cleaners head-to-head.
Flash Kitchen Degreaser vs Method Kitchen Degreaser (Clementine) — two standout products, tested across real-world cleaning power, user experience, and customer feedback.
The goal? To see how close the eco option comes — and whether the gap is really as wide as people think. Lets see if the switch is on!

Verdict: Both Respected, but One Still Leads on Grease-Cutting Power
Flash and Method both perform well in their own right, with strong user ratings . They’re designed for everyday use on oven doors, hobs, trays, and splash zones — the kind of surfaces that collect grease and buildup fast.
Flash consistently comes out on top for tougher jobs. It’s fast-acting, cuts through baked-on residue with ease, and is trusted by users who want results without repeat scrubbing. Method, by contrast, offers a smoother user experience — low fumes, pleasant scent, and a gentler formula — but often needs more time and effort to reach the same finish.
So which is better? That depends on your priorities.
If eco credentials come first, Method is a solid, planet-conscious choice that gets most of the job done.
If speed and strength matter more, Flash still has the edge — and eco alternatives aren’t quite there… yet.
FAQs
Q: Is Method safe for use inside ovens?
Yes — Method is suitable for use on oven doors, racks, hobs, and splash zones. For best results, apply shortly after cooking when surfaces are cool but not cold.
Q: Is Flash too strong for regular use?
No — Flash is designed as a daily-use degreaser. It’s powerful but safe for routine cleaning across most oven-safe and enamel surfaces. Avoid inhaling directly and always ventilate well.
Q: Is there a price difference between the two?
Surprisingly, no. Method works out at around £0.42 per 100ml, and Flash comes in at £0.44 — making them nearly identical in cost.
Q: Does Method leave streaks or residue?
It’s generally streak-free, but for heavy grease or glass oven doors, a second pass with a cloth may be needed.
