The first rule of removing protein-based stains like egg, blood and meat is do not put them into hot water. Hot water will set the stain in place making it much harder to remove in the long run. Like any stain the faster you tackle the problem the better the result.
- Cold water
- Bicarb soda
- Washing powder/liquid
As soon as fabric comes in contact with any protein-based stain take the item off and run it under cold water. Let the water from the tap go directly through the fabric where the mark is. This should be done until the stain has washed through. Or you can leave it to soak for an hour or two if the stain is particularly bad.
If there is still a mark you can add some bicarb soda and gently rub the fabric together then place into the washing machine on a cold, long wash cycle. Also add a 1/2 cup of bicarb soda to the washing machine.
Repeat the process for particularly stubborn stains.
