There’s no such thing as a single product that genuinely cleans an oven — not naturally, and not properly.

Ovens collect layers of baked-on grease, carbonised food and residue that harden over time. Trying to tackle all of that with one spray usually leads to frustration, harsh fumes, or damage to surfaces.

Natural oven cleaning works best when you treat it as a process, not a shortcut.

This guide shows you exactly how I clean my oven using a small number of DIY solutions — each one doing a specific job, in the right order.

 

Why oven cleaning needs more than one product

Different types of mess need different chemistry:

  • Grease and baked-on grime respond to alkalinity and abrasion
  • Carbon and cooked-on residue need dwell time
  • Oven racks clean best with oxygen soaking, not scrubbing
  • Leftover residue needs neutralising so it wipes away cleanly

That’s why this method uses several simple products instead of one aggressive cleaner.

Step-by-step: How I clean my oven

Prepare the Oven

  • Make sure the oven is completely cool
  • Remove oven racks and trays
  • Place old towels, cardboard or newspaper under the oven door to catch residue

This is a messy job — preparing properly makes cleanup much easier.


Clean the oven interior (walls and base)

I start by breaking down grease and baked-on residue with an alkaline paste.

Apply the paste generously to the inside surfaces of the oven, focusing on areas with visible build-up. Leave it to sit so the alkalinity can soften grease and carbon.

After the paste has had time to work, I follow up with a soap spray to help lift and remove loosened grime.

Scrub where needed using a cloth or steel wool, then wipe thoroughly.

 

Clean oven glass

Oven glass often has the toughest build-up, especially at the base.

For this, I use a scrub tablet or dishwasher tablet. Lightly damp it and scrub directly onto the glass. This gives controlled abrasion plus alkaline and oxygen cleaning, which works extremely well on baked-on residue.

Once residue lifts, wipe clean with a damp cloth.

 

Soak the oven racks

Oven racks are much easier to clean by soaking rather than scrubbing.

Submerge the racks in hot water, add sodium percarbonate, and leave them to soak for several hours or overnight. Oxygen cleaning loosens grease and carbon so it rinses or wipes away with minimal effort.

Rinse and wipe clean once soaking is complete.

 

Neutralise and final wipe

After all visible grime is removed, I finish with an acid-based spray.

This step neutralises any leftover alkaline residue and helps surfaces wipe clean without feeling chalky or sticky.

Wipe everything again with a clean cloth.

 

Tools I use

  • Steel wool (used carefully)
  • Old rags or cloths
  • Scrub tablets or dishwasher tablets
  • Towels or cardboard to catch residue underneath

No special tools required.


Important notes

  • Avoid essential oils in oven cleaners
  • Never mix cleaning products
  • Work in sections rather than rushing

This method is effective because it’s deliberate, not aggressive.
