Hi wish i could help -- i'm a bleachaholic ... my first thought is could you "dab" it with bleach? or would that run into the design?
here is what the Settlement cookbook says for chocolate: pretreatment: wash in hod suds treatment: soak in weak solution of household bleach or hydogen proxide, wash again
now i have never tried hydogen proixide ... i don't know what it will do to the color of fabrics. someone here mentioned using it safely on caret .... i'd really be interested in weather this wrks if you decide to try ... could you aplique over the spot?
good luck ...
