Grease stains can be very difficult to get out of clothing, and the thinner the fabric, the harder it is.
Experts at Vanish (opens in new tab) explain more, 'When dealing with cooking oil stains, it can be tempting to try and tackle them with water. However, oil stains are hydrophobic which means they repel water molecules. So only add water to the stain if you are treating it immediately.'
Timing is always of essence with removing grease stains (blot, blot, and blot!), but if you've noticed the stain after it's settled, there still are cleaning tricks you can try to get rid of it.

How to remove grease stains with baking soda/starch
Another effective way to remove grease stains is by sprinkling the stain with baking soda, starch, or corn flour.
These powders will work by absorbing the grease, and all you need to do is brush off the excess afterwards.
However, this method tends to be more effective on fresh grease stains than old and dried ones.
How to remove grease stains with ammonia/ steam cleaner
If you do have a dried grease stain, you need to bring out the big guns. So, how to remove grease stains that have dried in? Ammonia is the answer.
Ammonia has an extremely alkaline chemical profile (pH o 11.6), which is perfect for treating organic stains that are acidic in nature (mayonnaise has a pH of 3.6, for example).
Use very sparingly, as it's strong stuff, and never on delicate or non-colorfast garments. Blot a little ammonia in, then apply steam from a steam cleaner or clothes steamer, blotting away the rest of the stain as you go.

How to remove grease stains from delicate fabrics
If you've got a grease stain on a silk garment/thin synthetic one, you can't use any of the methods above, apart from, with caution, the dish soap one.
Sadly, if you have a grease stain on a silk shirt, you'll have to accept that it's there for good; it may diminish over time with laundering, but is unlikely to completely disappear.
If you notice the stain while it's still fresh, you should be able to blot away most of it, but again, if the grease has soaked through the silk thread, it's likely to be permanent.
You could try an effective stain remover to oust the stain. Find out how to remove grease stains with stain remover below.

If all these methods sound a bit too time-consuming, you can just chuck your grease-stained clothing item into the wash, onto the hottest temperature the fabric will tolerate, but you'll likely find that the stain won't budge even after washing.

Experts at Vanish shared their top tips on how to remove grease stains:
- 'To remove oil from fabrics that are machine washable, you need to tackle the stain quickly. To stop the stain from spreading through to the other side of the garment, take a clean paper towel or cloth and dab the oil stain, being careful not to spread the stain.'
- 'Pour 2ml of Vanish Gold Oxi Action gel (opens in new tab) onto the stain.'
- 'Gently rub the gel into the stain using the underside of the cap to work the Vanish into the stain.'
- 'Leave for 10 minutes (max).'
- 'Wash as usual with detergent and add 60ml of Vanish gel for best results.'
