DS1's white school shirt has I think paint splatters all up on arm. Normal washing didn't shift it, nor has nearly a week soaking in a bleach solution ( which I've added more bleach to to make it stronger....)
What next to get the marks out? The shirts are monogrammed with the school logo and about 30euros to replace so would rather salvage it if at all possible.
Would white spirit be worth a try.... paint could be oil based perhaps??
Any suggestions gratefully received!
