Once you've washed them put them in bright sunlight to dry if possible, if I doesn't get rid completely it massively fades the yellow stain
I soak l my little ones soiled clothes in plant based washing up liquid and hot water before scrubbing the stain and then putting them in the wash at 40.. seems to do the trick as long as you catch the stain fairly early
I use the pink stuff spot stain remover from b&m. Spray before goes in the wash and it works nearly every time xx
As soon as you take the clothes off put in cold water to soak then wash as usual.
We have napisan stain remover, works perfect and is designed for baby mess! 😊
I use napisan. Really really good!
I use Milton sterilising fluid - works a treat!
Napisan!
Pink stuff spray
Soak in napisan first and then wash as normal with napisan
How are you washing them?
