* dampen the clothing with cold water and rub baking soda both sides and leave it sit, rinse with cold water then wash as usual
* dish soap breaks down stains quite well too, put pure dishsoap on the stain, leave it sit then rinse with cold water and wash as usual
* sunlkight block soap; dampen the stain with hot water, rub it with sunlight block soap and then scrub, rinse with hot water and repeat as often as needed
* distilled white vinegar is the best choice for a natural cleaner. It’s colorless and contains acetic acid that can help break down stains, but is mild enough for use on colorfast fabrics.
* when all else fails try hydrogen peroxide to remove chocolate stains

I think once it washed and maybe ironed it’s kind of stained permanently like a die. I would now just try to scrub it with a good old fashioned sunlight soap block and piping hot water and repeat multiple times, it may fade but not totally get out

depends on the look of the jeans but if you get really stuck, try some bleach

Soak in warm water with Vanish Napisan Oxi Action Powder.

I always soak in cold water with some napi san or other soaker – with chocolate you sometimes have to repeat this process as they are stubborn stains to get rid of!

chocolate stains can be hard – I use pre wash spray and then soak. had to do it three times to get the last chocolate stain out!

Remove the chocolate residue using a butter knife or spoon. Be careful not to spread parts of the chocolate to clean clothing.
Never rub or scrub a chocolate stain. This will embed it into the fibers of the fabric, making it harder to remove. Rinse the back of the area that’s stained with cold running water. Doing this releases some of the stain, preventing it from going through any more of the fabric. Never use hot water on a chocolate stain; this will set it permanently. Rub laundry detergent into the stain. Let the clothing sit for up to 5 minutes and allow it to soak up to 15 minutes in cold water. Rub the stained area (between the thumb and all other fingers), which makes the stain looser. Rinse, and continue until the stain is totally gone. Use a stain remover to remove any remaining stain. Do this if any stain remains after finishing the rubbing process, and the stain has set on the fabric. Make sure that the stain has been thoroughly removed. Once you’re certain it has been removed, dry the clothing as per your usual routine. Do not iron or heat dry until all traces of the stain have gone or the stain will set permanently.

there are some good comments here

you could try preen spray .. . .

would bleach work in this case?

try soaking in Napisan overnight, eucalyptus is also good for grease stains.

I’ll have to try some of these suggestions

I like the hair spray idea. never heard that one. im going to try it.

try hair spray on the spot, leave to dry and then wash as normail

Did you manage to get the stains out?

Make a paste out of basis an and water an rub it on the stain.

Maybe time to ask for professional help? Not sure if you can dry clean jeans?

napisan works wonders its great 🙂

Maybe try napisan, it works for most clothing

Grandmas Secret Spot Remover…works in washed & dried in stains.
