How to Clean an Oven: The Ultimate Guide

Cleaning your oven tends to be one of the most avoided jobs in the kitchen. We put it off for as long as possible, dreading scrubbing off grease and accumulated residue, and removing burnt bits of food.

But it doesn’t have to be this way. Cleaning the oven may be a big task, but there are ways to make it easier and more bearable. And the reward is a sparkling clean oven that feels worth the time and trouble.

That’s why we have developed the ultimate guide to cleaning your oven, broken down by area including the racks, trays and oven glass.

Why should you clean your oven?

Faced with such an unpopular chore, it’s easy to ask yourself why you even need to clean the oven. But dirty ovens can be dangerous, and can lead to the following consequences:

  • Visible discolouration
  • Damage to the oven
  • Grime on the glass
  • Extensive smoke output
  • Fire hazards
  • Reduced oven life

Fire Safety

If you don’t clean the oven for a while, grease and stray bits of food can get left inside. This can cause extensive smoke output the next time you cook as the food will continue to burn, resulting in a fire hazard. The smoke can trigger fire alarms and the bitter, burnt flavour may impact the taste of your meal.

Choosing the best oven cleaner

As with any tough job, the right tools make it easier. And the quality of your oven clean will be dependent on the type of oven cleaner you use. There is a selection of cleaning products on the market, ranging from strong solutions that make for easier cleaning and target heavier stains, versus ones with a low chemical concentration that result in a lighter clean and more scrubbing.

Most people are unaware of the toxic chemical in many oven cleaning products – sodium hydroxide. Whilst the chemical is highly effective as a cleaner, it can also be highly corrosive. There are domestic cleaning products in the market that do not include these harsh chemicals, but they tend to be less effective.

For more information and our recommendations for different cleaning requirements, read our guide on the UK’s best oven cleaners.

Natural oven cleaner

Some people prefer to avoid oven cleaners and use natural cleaning products instead. One common solution is bicarbonate of soda and vinegar:

  1. Mix half a cup of bicarbonate soda with a few tablespoons of water
  2. Paste the mixture all over the interior of the oven, keeping away from any electrics
  3. Leave overnight
  4. Using a damp cloth, clean away the mixture
  5. Next, coat the area by spraying vinegar on all surfaces, avoiding any electrics
  6. Clean out any remaining residue and repeat if necessary

Note that natural oven cleaners may require repeat applications to shift stubborn stains and grease.

The best way to clean your oven


Here is our ultimate guide to cleaning your oven. It runs through each individual step in detail for a thorough deep clean. It’s important to cleanse all components.

Checklist: What do you need?

You will need the following equipment to undertake your own oven clean:

  • Oven cleaner of your choice
  • Rubber gloves
  • Sponges
  • Scourer
  • Large resealable plastic bags
  • Kitchen towels to line the floor
  • Clean cloths


Time taken: 5 minutes
  1. To begin ensure the oven is switched off at the mains – this is important as you will be using liquid cleaners in an electrical appliance.
  2. The oven should be cold before you start cleaning.
  3. Put rubber gloves on and ensure arms and wrists are covered at all times.
  4. Open windows – this helps ventilate any chemicals.
  5. Remove any loose bits of dirt and burnt food.

Cleaning the oven racks

Time taken: 30 minutes plus soaking time

  1. Begin by removing the oven racks and knocking off any stuck-on food or debris.
  2. Place them in the large sealable bags with solution and leave for 4-6 hours or overnight. This will remove most of the tough residue.
  3. Remove the racks from the bags and scrub the remainder of the residue off with a scourer and hot, soapy water.
  4. Then rinse and dry immediately.
  5. Return to the oven once you’re finished cleaning everything.

Note: If you don’t want to use the plastic bags that come with oven rack cleaning products, sealing your racks in a rubbish bag is an alternative.

Or try soaking the racks in the sink in warm water mixed with washing up liquid. Leave them in there for a few hours, preferably overnight. Then continue with the steps as above.

For more information and tips read our guide on How to clean your oven racks.

If you still have stains or food between the oven windows, read our guide to cleaning between your oven door glass.

Cleaning oven trays

  2. Place the trays in the sink and run warm water until the trays are sufficiently covered.
  3. Add biological washing powder and mix, this helps break down any stubborn oil stains.

Things to watch out for

Ovens are an important household appliance and often described as the heart of the kitchen. Many of us use them daily, especially during the winter months when we want warm, nourishing dinners.

But this regular use means they can quickly pick up wear and tear, and they are very expensive to replace. When you clean your oven, you will be more likely to spot damage earlier on, helping to extend the life of your oven.

If you do decide to clean your oven at home, it’s important to check for any damage. We’d recommend you look out for the following issues:

  • Damaged rubber seal around the oven
  • Damaged parts or parts that aren’t sitting straight
  • Faulty or newly visible electricals

If these issues do arise, it’s best to get a professional in to assess the damage and fix it.

Professional oven clean versus DIY

You can clean your oven yourself, especially when armed with plenty of time and the right products. But many people are turning to professional oven cleaners – here are some of the advantages:

A deeper clean

Some cleaning solutions will claim to provide a deep clean, but they are often limited to just targeting grease and light surface grime. They won’t be able to remove any carbon deposits or built up dirt in filters and mechanisms.

If there is dirt left in the mechanisms, over time it can affect the functioning of the oven and make it less efficient, decreasing its life span. A professional oven cleaner will be able to get deeper to remove grease deposits in the mechanisms.


Professional oven cleaners have the ability to dismantle your oven and reassemble it. They understand how it works and which bits to take apart to get the best clean. They can also carry out a maintenance examination to find any damage that has occurred.

In comparison, home cleans are not as thorough. Therefore, having a full service means you have the comfort of knowing your appliance is working to its optimum efficiency.

Professional equipment – mess free

Home cleans can often expose you to harmful chemicals and become a very messy task that results in a big cleanup. At Ovenclean, we use safe, non-toxic and non-caustic products to maintain a hygienic and chemical-free environment.

Our products allow you to use the oven as soon as we leave. In addition, when we soaking oven components, we place them in a bath outside your house so your home can stay spotless.
