Remove Old Grease Stains with Bicarbonate of Soda, Baking Paper and an Iron

Those stains that seem to last forever can often be shifted with a simple little trick. No pricey specialist product, no hours of scrubbing - just a clever method using things found in most kitchens. One everyday household appliance that’s usually out at least once a week plays the key part.

Why old grease stains are so stubborn

Grease marks that have been sitting in fabric for a while behave very differently from fresh splashes. While the stain is still soft, you can often lift a lot of it with kitchen roll and a bit of washing-up liquid. Once the grease has dried, though, something else happens.

The grease molecules work their way deep into the fibres - especially in cotton, denim, or sturdy blended fabrics. In the wash, detergent may clean the surface, but the hardened core of grease within the fabric can remain. Each time the item is dried, that residue tends to lock itself in a little more firmly.

"The crucial point isn’t the detergent - it’s the grease that has settled in and needs to be brought back into motion."

If you respond by scrubbing harder or washing hotter, you often end up with the worst of both worlds: the fabric takes a beating, the stain stays put, and the frustration climbs.

The unassuming kitchen trio

The fix relies on three straightforward helpers that many households already have to hand:

• bicarbonate of soda (often sold as bicarb or baking soda)
• baking paper
• an iron with an adjustable temperature

Together, these make use of a simple physical effect: gentle heat turns set grease more fluid again so it can move out of the fabric. At the same time, the bicarbonate of soda absorbs the grease as it emerges, while the baking paper acts like a clean, stable “blotter”.

"Heat gets the grease moving again - bicarbonate of soda and baking paper catch it at just the right moment."

Which fabrics this method suits

This trick tends to work particularly well on:

• cotton T-shirts and sweatshirts
• jeans and tough cotton canvas
• cotton or polycotton tablecloths
• kitchen towels and tea towels
• durable synthetics, such as aprons or workwear

Be more cautious with delicate materials:

• silk
• wool and cashmere
• leather and suede
• fine velvet
• coated or proofed fabrics

With these, heat can quickly cause shiny patches, alter the texture, or damage a coating. In such cases, it’s safer to use cold methods or go to a dry cleaner - or at least test first on a hidden area.

What you actually need - and what to avoid

For this to work properly, the specific type of each helper matters.

Bicarbonate of soda: the powder base

The main ingredient is plain bicarbonate of soda powder, whether food-grade or household-grade. What matters is that it stays dry, fine, and unblended.

• Best: pure bicarbonate of soda, tightly sealed, without added fragrance
• Amount: usually 1–2 teaspoons for a typical stain
• for large areas (such as tablecloths), use more accordingly

Scented powders or mixed products can behave unpredictably, leave lingering odours, or reduce how well the powder absorbs.

Baking paper instead of kitchen roll

In this situation, baking paper is clearly better than kitchen paper. It doesn’t shed fluff, it tolerates the heat of an iron, and it won’t stick to the fabric.

"The small difference: baking paper protects both the fabric and the iron’s soleplate, while collecting the grease."

A rectangle folded several times is enough, as long as it generously covers the stained area. Cling film is not suitable - it will simply melt under heat. A regular cloth tends to absorb grease unreliably and often spreads it further.

The iron as the turbo

Rather than just smoothing laundry, the iron is used here as a controlled heat source. Two settings are essential:

• a gentle temperature, towards the low-to-medium range
• no steam function - dry heat only

Steam introduces moisture, which can make grease stains spread and form rings. Excessive heat can also effectively “bake” grease into the fibres.

The two-minute method, step by step

With a little prep, the whole process can be done in roughly two minutes.

1. Prepare a base layer
   Place a clean terry towel or an absorbent piece of cardboard under the affected area. This prevents released grease from soaking through to the back of the garment or into the ironing board.

2. Get the stain ready
   For fresh marks, gently blot with kitchen roll - don’t rub. For older stains, lightly brush with a dry, soft brush to remove any loose residue.

3. Sprinkle on bicarbonate of soda
   Dust the stain with a thin but complete layer. Avoid thick heaps; aim for an even coating like fine powder. Don’t vigorously rub it in, otherwise the grease can be pushed deeper into the fibres.

4. Lay on the baking paper
   Place a folded piece of baking paper over the dusted area and smooth it lightly without pressing down. A calm, flat surface is the goal.

5. Iron with gentle pressure
   Set the iron to a low-to-medium temperature and switch steam off. Briefly place the iron on the baking paper for a few seconds at a time, then move it slightly and repeat until you’ve covered the whole area.

6. Check the result
   Lift the baking paper and look: if the paper becomes a bit more translucent or shows light marks, grease has migrated outwards. Ideally, the stain on the fabric already looks paler or nearly gone.

7. Repeat if needed
   If a clearly visible patch remains, apply a fresh layer of bicarbonate of soda, use a clean section of baking paper, and run through the steps a second time.

8. Wash as normal
   Finally, wash the item or tablecloth as you usually would. Check again before drying - if the stain is still faintly visible after washing, don’t use a tumble dryer; repeat the treatment instead.

Typical mistakes - and how to avoid them

The same mishaps crop up in many homes. If you know the common pitfalls, you’ll protect your textiles far better.

Mistake	Result	Better approach
Iron too hot	Stain sets in; fabric turns shiny	Choose a medium setting; work in shorter bursts
Turning on steam	Rings; a larger stained area	Use dry heat only
No absorbent layer underneath	Stain transfers to the reverse side	Put a towel or cardboard underneath
Scrubbing hard	Fibres damaged; stain spreads	Use gentle handling; let heat do the work
Washing then straight into the tumble dryer	Stain becomes permanently fixed	Always pre-treat first, then run the wash

How different types of stains respond

Not all grease behaves the same way. Some marks are a combination of fat and colour.

• Butter, roasting juices, creamy sauces: These often leave a greasy core plus a slight discolouration. The iron trick draws out the fat; afterwards, a piece of solid soap (for example, an unscented vegetable soap) can help lift any remaining colour.
• Cooking oils, deep-frying fat: Usually colourless but very persistent. Two rounds with bicarbonate of soda and baking paper often make the difference.
• Oil-based make-up: Here it helps to pre-treat with a little soap or mild washing-up liquid before applying heat.

The most common damage happens when clothing with untreated grease marks goes straight into the tumble dryer. The heat there acts like a fixative, anchoring the stain permanently in the fabric.

Practical household strategy: make a small stain emergency box

If you cook often, have children at home, or like working with oil and sauces, a small ready-to-go kit can save time and stress:

• a jar with about 200 grams of bicarbonate of soda, tightly sealed
• a roll of baking paper, with a portion reserved specifically for stain treatment
• a bar of solid soap for leftover colour
• two clean microfibre cloths and an older terry towel for use as an underlayer

With a mini kit like this, everything is ready when fat spits during a Sunday roast or salad dressing drips onto jeans. Acting quickly matters - particularly for fresh marks: blot first, treat next, and don’t just “throw it in the wash later”.

When it’s better to go to a dry cleaner

Even with good tricks, there are limits. Very delicate fabrics, multi-layered items such as suit jackets, or high-quality lined garments can react badly to at-home experiments. If grease has spread across a large area - for example, a full spill of oil - it’s often worth taking it to a dry cleaner as well.

If, after several attempts, a noticeable ring remains or the fabric feels different, it’s wiser to stop. In those situations, professionals can treat the textile surface in a targeted way without ruining the fibres. For everyday use at home, though, the three-piece team of bicarbonate of soda, baking paper and an iron is still a surprisingly reliable lifeline - especially for the classic kitchen and dining-table mishaps that can happen to anyone.
