Looking for a REALLY good stain remover

[Dannythedragon]

DS has got various stains on his school PE shirts that just won't shift. I've tried Shout spray, a long soak of Vanish stain remover and now the Clorex bleach pen but so far nothing has helped, What else is there to try? Some of the stains look like whiteboard marker and some I know are the ELC paint from the sponge painting set ("may stain" my arse). The shirt is white polyester but with a navy trim so I can't just dunk the whole thing in bleach.
Thanks

Have same problem with DS polo shirt and DD1s PE top. Ive tried everything and DD1s PE top got so bad i ended up chucking it as even bleach didnt work! DSs polo shirt is blue so cant do that with his anyway. The only thing i found to be half decent was dr beckhams stain remover which was 89p for homebargains (i kid you not) but if you dont have one i think you can buy it online.

White board marker is the work of the devil, good luck!

rubbing the stain with oil or butter then washing with added soda crystals helps but will not completely shift white board markers...

Hi, ariel do stain removers - stain remover and whitener (for whites) and a stain remover (for colours), they're not cheap mind, but i would use the one for colours on the polo shirt with navy trim.

My mum swears by bio-tex and it does get out stubborn stains that nothing else will if you soak it first.

Thank you
