When You Need Something That Stays Put
Sprays are great for general oven cleaning, but there are times when you need something with a bit more staying power. When grease has been baking onto a surface for months — or years — a spray can struggle to cling long enough to do its job properly.
That’s where the Dirtbusters Bio Oven Cleaner Paste comes in.
What Makes the Paste Different?
The paste is the same professional-grade, non-caustic, fume-free bio formula as the Dirtbusters spray — but in a thick paste form. That thickness is the whole point.
Where a spray can run off vertical surfaces or evaporate before it’s had time to work, the paste clings. It stays exactly where you put it and keeps working for longer. That extended dwell time is what makes it particularly effective on heavily soiled ovens and stubborn baked-on carbon deposits.
It’s the product professional oven cleaners reach for when a spray isn’t quite enough.
When to Use the Paste vs the Spray
Both products are non-caustic and safe for home use, but they suit different situations.
Use the spray when:
- You’re doing a routine clean of a regularly maintained oven
- You’re cleaning large flat surfaces quickly
- You’re wiping down fascias, hobs or splashbacks
Use the paste when:
- You’re dealing with heavily baked-on grease and carbon
- You need the product to stay on a vertical surface
- You’re tackling the inside roof of the oven where spray runs off
- It’s been a while since the last deep clean
For the best results, many professional cleaners use both — spray for the general surfaces and paste for the problem areas.
How to Use the Paste
Apply a generous amount of paste directly to the soiled surface using a cloth or brush. The paste should cover the area completely — don’t be shy with it.
Then leave it. This is the most important step. The bio formula needs time to break down the grease and carbon, and the paste’s thick consistency means it stays in contact with the surface for as long as you need. For heavy soiling, leave it for at least 30 minutes. For really stubborn areas, you can leave it longer.
After the dwell time, wipe away with a damp cloth. The loosened grease and carbon should come away cleanly. For any remaining stubborn spots, a gentle scrub with a non-scratch pad will finish the job.
The formula is gentle on surfaces, seals and oven glass, so you don’t need to worry about scratching or damaging enamel.
Safe for the Whole Family
Like the spray, the paste contains no caustic chemicals and produces no harmful fumes. It’s non-toxic and safe to use around children and pets. You can use your oven immediately after cleaning — no burning off residue, no airing out the kitchen.
It works on all oven types including fan-assisted ovens, AGAs, hobs, grills, racks, trays and BBQs.
Final Verdict
If your oven hasn’t been cleaned in a while, or if you’re dealing with genuinely baked-on grease that a spray hasn’t shifted, the Dirtbusters Bio Paste is the tool for the job. The extended dwell time does the heavy lifting and the non-caustic formula means you can apply it without any of the risks associated with traditional caustic cleaners.
Used alongside the Dirtbusters spray, you’ve got a complete professional cleaning system for your kitchen.
