I swear by a block of pure soap and a good hard nail brush. I soak the stain in hottest possible water and rub it with soap and then scrub over and over again. I have made up a spray bottle with diluted bleach what I sometimes spray on the stain (depending on the colour of the garment) and leave it shortly in, then rinse. When all of that doesn’t help I set it in the napisan soak (or any soaker alike) and leave it for some days. I might give it another scrub with pure soap before I add it to the washing machine.

I use orange power pre-wash stain remover. I dampen the area of the stain, spray it and give it a good rub. Often the stain comes straight out. If not don’t rinse it, just put it in a bucket of water overnight, then wash as normal. I know a lady who uses the Napisan method but I have never tried it.

napisan or bleach. try that and see how you go.

make a paste out of napisan or similar and rub it directly onto the area and then soak over night. worked most of the time for us.

I swear by Napisan, may need more then one attempt, but you eventually get the stain out. Lemon juice is good too. Squeeze some onto the stain, rub it in and leave to dry in the sun. Wash as usual. Also sometimes takes more then one go

I find eucalyptus woolwash is very effective and kind to clothes. Pour on neat leave to soak in and then put into the wash. It worksi on most fabrics, great for carpets too. Can be foamy if you use too much.

Soak it in napisan for a couple of days, change the water daily.
