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

A T‑shirt that looks beyond saving, a tablecloth coated in grease, a tea towel covered in marks - and the washing machine isn’t shifting them?

A straightforward kitchen trick often tackles old grease stains faster than many specialist products.

Plenty of people give up in frustration when greasy marks are still visible even after several washes. The culprit is rarely the detergent brand; it’s usually how far the grease has worked its way into the fibres. With a three-part combination of everyday household items and one appliance most people use weekly, you can loosen these stains surprisingly quickly - without harsh chemicals and without wrecking the fabric.

Why old grease stains are so hard to remove

New splashes of fat can often be dealt with using a little washing-up liquid and a standard wash cycle. Once the grease has dried, however, it changes: it hardens and effectively anchors itself in the weave.

Old grease stains aren’t just sitting on the surface - they’re lodged in the heart of the fibre, which is why even a strong wash can’t shift them.

Certain fabrics are particularly prone because they absorb grease like a sponge:

• Cotton (T‑shirts, bedding, tea towels)
• Denim
• Heavy canvas
• Terry towels
• Tough synthetic blends (for example, workwear)

In the wash, detergent may clean what you can see on the outside, but the greasy core often stays trapped inside the fibre. Each tumble-dry cycle can set that residue further. This is exactly where the kitchen method helps: the grease needs to be mobilised again before it can be lifted out.

The unexpected dream team for grease: powder, paper and heat

This approach relies on three simple items that many homes already have:

• Sodium hydrogen carbonate (bicarbonate of soda / “bicarbonate”)
• Baking paper
• An iron on a low setting

Each one has a clear job:

Component	Purpose
Sodium hydrogen carbonate	binds to and absorbs the loosened grease
Baking paper	acts as a clean barrier and “grease catcher”
Iron (no steam)	provides gentle warmth to liquefy the grease

The mix of mild heat and strong absorbency draws grease out of the fibre instead of simply smearing it around.

Used this way, old grease stains often look noticeably lighter - or disappear entirely - before you even put the item back in the wash. The upsides are obvious: no sharp chemical smell, no caustic cleaners, and minimal risk on sturdy fabrics.

When the trick works well - and when it doesn’t

It’s well suited to items such as:

• Cotton T‑shirts and shirts
• Jeans and chinos
• Tea towels, napkins and tablecloths made from cotton or linen
• Towels and flannels
• Hard-wearing man-made fibres (for example, polyester blends)

More delicate materials need a lot more care:

• Silk
• Wool and cashmere
• Leather and suede
• Velvet and fine velour
• Coated fabrics (outdoor jackets, wipe-clean tablecloths)

On these, heat can quickly cause shiny patches, distort the shape, or damage coatings. In those cases, a professional dry cleaner or a cold-treatment stain remover is usually the better choice.

As a general rule, if you’re unsure - or the item is very dark or heavily printed - test first on an inconspicuous area to make sure the warmth doesn’t alter the fabric.

What you actually need

This two-minute fix doesn’t require any specialist products. Ideally, have the following ready:

• Household bicarbonate of soda (food-grade or cleaning-grade) - as pure, dry and fragrance-free as possible
• Baking paper - not kitchen roll and not cling film
• An iron with temperature control, with steam switched off
• A thick, clean base layer, such as an old towel
• Optional: soap flakes (hard household soap) or a traditional vegetable-oil bar soap for any leftover colour halo

A key point with bicarbonate of soda: a light dusting is enough. For a typical T‑shirt stain, two teaspoons is often sufficient. Scented versions or mixed products tend to be less reliable because added ingredients can reduce how well the powder absorbs grease.

Step by step: the express method

1. Prepare the stain

If you start ironing immediately, you may simply spread the grease further. A better approach is:

• For fresh stains, gently blot with kitchen paper - don’t rub.
• For older stains, lift any loose residue with a soft brush.
• Place a thick towel or a piece of cardboard underneath the stained area.

That backing stops grease transferring to the reverse side of the fabric or straight onto the ironing board.

2. Sprinkle on the bicarbonate of soda

Now add the powder. Dust the affected area thinly but evenly. The aim is a light “snow” over the stain, not a mound.

The bicarbonate of soda should only sit lightly on the fibres. Vigorous rubbing pushes grease deeper into the fabric - the exact opposite of what you want.

3. Cover with baking paper

Fold a piece of baking paper in half and place it over the powdered section. Press the edges down slightly so it doesn’t slip. Unlike kitchen roll, baking paper won’t tear easily and remains stable when warmed.

Cling film is a non-starter: it can melt and stick to the textile. Brightly coloured cloths are also risky because they may just move the grease around or leave their own marks.

4. Work with low heat

Set the iron to a low-to-medium temperature and keep steam off. Then follow the crucial technique:

• Place the iron down - don’t glide it back and forth.
• Apply light pressure for a few seconds, then move to the next spot.
• Keep going for roughly one to two minutes in total.

If you like, lift a corner now and then to check. If the baking paper starts to look slightly translucent in places, that’s a clear sign grease is being drawn out.

5. Check the result and treat again if needed

After the first round, remove the paper completely and gently shake off the powder or brush it away with something soft. Very often you’ll already see the stain has lightened considerably, or it’s nearly gone.

If there’s still a trace, simply repeat the process using fresh powder and a clean area of baking paper. After that, run a normal wash cycle, ideally matched to the care label.

Common mistakes - and how to avoid them

Many attempts fail because of small errors. The most common are:

• Iron too hot: excessive heat can “bake in” grease and permanently set the stain, especially on synthetics.
• Steam switched on: moisture spreads grease through the fabric and may create unpleasant rings.
• No absorbent layer underneath: without a towel or cardboard, the grease can just seep through to the back.
• Scrubbing too hard: stiff brushing can polish fibres and leave pale shiny patches, particularly on dark denim.
• “Just washing it” without pre-treatment: putting it straight into the machine and then the tumble dryer significantly reduces the chance of saving it.

Special cases: butter, oil, make-up and more

Not all greasy substances behave the same way. A few everyday examples:

• Butter and cream sauces: these leave grease plus colour pigments. The heat-and-bicarbonate method tackles the grease first; afterwards, a bar of hard soap or a firm household soap can help with any remaining discolouration.
• Cooking oils and deep-frying fat: usually very stubborn, but they often respond well to repetition. Two rounds with bicarbonate of soda and baking paper can be the turning point.
• Make-up and lipstick: it’s often worth gently working in a little soap first, and only then moving on to the heat treatment.

Practical household checklist for grease stains

Setting up a small stain-fighting corner in the cleaning cupboard saves time and stress. Useful basics include:

• a jar with 200 grams of bicarbonate of soda, tightly sealed
• a roll of baking paper reserved specifically for stain rescue
• a piece of hard soap or vegetable-based household soap
• two old but clean cotton cloths and a “sacrificial” towel to use as an underlayer

With this kit to hand, the rescue attempt rarely takes more than a few minutes, including prep. Acting early - before the item has been washed over and over - gives you the best odds.

When it’s better to use a professional - and what you can take from it

The method has limits: very delicate fabrics, very large stains, or marks that have effectively been heat-set several times can be beyond a home fix. For high-quality suits, evening wear or padded jackets, a professional cleaner is often the less stressful option.

The everyday principle is still useful, though: let something absorb the grease first, use gentle warmth to get it moving again, and then remove it in a controlled way. Stick to that and you’ll be far less likely to bin favourite items because of an oily splash - whether it happens at a family meal, while cooking, or during a quick snack on the sofa.
