How to Clean Oven Racks in the Bathtub with Baking Soda and Washing-Up Liquid

With one straightforward method, this becomes remarkably easy.

Burnt-on fat splatters, baked-on marinade and dark crusts: after a few months of everyday use, oven racks can look truly dreadful. Anyone who has tried scrubbing them in the kitchen sink will know the frustration – water everywhere, only half the rack submerged and virtually no results. Yet there is a surprisingly simple solution that hardly anyone uses, and it works without harsh chemicals.

Why oven racks stay so stubbornly dirty

In many homes, cleaning the oven has become part of the routine: the glass door, interior walls and sometimes even the baking trays. The rack, however, rarely gets included in this cleaning session. There are several obvious reasons for this.

• It is bulky and often will not fit fully into the kitchen sink.
• The gaps and edges are difficult to reach.
• Fat and sugar from marinades bake directly onto the metal.
• Many people avoid the effort and put it off “for later”.

When they do eventually reach for a cleaner, it is often an extremely strong oven cleaner. While these products remove plenty of grime, they can give off a pungent smell, irritate the airways and gradually damage the metal surface. In short, they are unpleasant for both people and materials.

An unexpected place with impressive results: the bathtub as the secret weapon

The key issue with an oven rack is its size. That is precisely where the surprisingly obvious answer lies: rather than struggling at the kitchen sink, simply put the oven rack in the bathtub.

There is enough room for it to be fully submerged. This allows every centimetre of the metal bars to soak, which is essential if baked-on grease is to loosen at all.

Soaking the oven rack in the bathtub saves a great deal of scrubbing while being kinder to both the metal and your nerves.

To avoid damaging the bath enamel, one simple measure is enough: place a thick old towel, a bath mat or two large towels on the bottom of the bath. This provides cushioning, prevents scratches and softens the noise when heavy racks are lifted in or out.

The cleaning mixture: three simple ingredients with a powerful effect

There is no need for specialist cleaning products. All that is required are three things found in almost every home:

• very hot water
• baking soda (sodium bicarbonate)
• grease-cutting washing-up liquid

Each ingredient has a clear role:

• Hot water softens dried food residue and hardened grease.
• Baking soda is mildly abrasive and helps lift layers of grease and dirt.
• Washing-up liquid breaks fats down into smaller particles so that they release from the metal.

The following proportions have proved effective:

Ingredient	Recommended amount
Baking soda	approx. 150 g per bathful
Washing-up liquid	approx. 50 ml
Water	enough to cover the rack completely

If you do not have a measuring jug, use this as a rough guide: 150 g of baking soda is around one generously heaped coffee mug, while 50 ml of washing-up liquid is just under one third of a standard small bottle.

How to clean oven racks step by step

1. Prepare the bathtub

Lay the towel in the dry bath and place the oven racks on top. If there is more than one rack, they can overlap slightly as long as water will be able to reach every part later.

2. Fill with hot water

Fill the bath with hot water until the racks are fully submerged. The hotter the water, the more effectively the dirt will loosen. It does not need to be boiling; very hot tap water will be sufficient in most cases.

3. Add baking soda and washing-up liquid

Sprinkle the baking soda evenly over the water surface. Next, add the washing-up liquid and gently stir everything with your hand or an old brush to distribute both ingredients through the water. A little foam is perfectly fine.

4. Leave it to soak: patience pays off

Allow the racks to soak for at least 30 minutes. For normally dirty racks, this is often enough. If they have not been cleaned for years or have heavily burnt-on residue, they can safely remain in the bath for several hours or overnight.

The longer the rack sits in the mixture, the more work the water does – and the less scrubbing you will need afterwards.

5. Finish gently rather than scrubbing hard

Once the soaking time has passed, wipe away the loosened dirt with a soft brush or the regular side of a washing-up sponge. In many cases, the sponge will glide over the metal almost by itself because the grease and baked-on deposits have already released.

6. Rinse thoroughly and dry

Rinse the racks with clean water until no foam remains. Then dry them properly, either with a tea towel or by leaving them to air-dry. To prevent rust marks, it is best to quickly wipe the bars dry before putting the rack back into the oven.

Why this oven rack method is kinder to the metal

Compared with strong oven cleaners, the combination of baking soda and washing-up liquid works much more gently. It does not attack the metal’s protective layer, helping the surface retain its shine. As very little force is needed, brushes and sponges wear out more slowly and fewer micro-scratches are created.

It also reduces exposure to aggressive fumes, which is particularly beneficial for people with sensitive airways. Households with children or pets also benefit from this lower-chemical approach.

How often should oven racks really be cleaned?

There is no fixed rule, but a general guide is useful. Anyone who regularly grills, makes bakes or cooks meat directly on the rack should use the bathtub method after periods of intensive cooking.

• Occasional bakers: every 3–4 months
• Frequent users dealing with plenty of grease and marinade: about once a month
• After “extreme incidents”, such as overflowing bakes: as soon as possible

Keeping to a loose routine prevents five or six layers of grease and sugar from building up on top of one another. Each clean then becomes noticeably quicker and easier.

What to consider with coated racks and cast iron

Many modern ovens have chrome-plated or enamelled racks, while some appliances use cast iron. For the baking soda and washing-up liquid method, the following applies:

• Chrome-plated racks: generally unproblematic, but do not use harsh metal scourers.
• Enamelled racks: use soft sponges and do not scrape with sharp knives.
• Cast iron: dry thoroughly after cleaning to prevent surface rust.

If you are unsure, test the method on an inconspicuous area before soaking the entire rack. Baking soda is very mild, but it is still worth checking the oven manufacturer’s instructions, especially for specialist coatings.

Practical habits for a permanently cleaner kitchen

A few small habits can stop an oven rack from reaching disaster level in the first place:

• Whenever possible, place a baking tray underneath greasy oven dishes to catch drips.
• Once it has cooled, quickly wipe away dripping marinade before using the oven again.
• When next cleaning the bathtub, include the rack and baking trays at the same time – one task, double the benefit.

Anyone who uses baking soda regularly may wish to keep a larger supply. Packs of the powder are inexpensive, have an almost unlimited shelf life and are useful for other household jobs too: cleaning pan bases, neutralising odours in the fridge or serving as a gentle scouring powder for the kitchen sink.

The bathtub method shows just how effective basic household products can be when they are combined intelligently. Rather than kneeling at the oven with a face mask and specialist cleaner, let hot water, baking soda and washing-up liquid do the work quietly. It saves time, is easier on the nerves and, as an added benefit, leaves the oven rack looking as it did when it first came out of the box.
