How to get a grass stain out of my white high heel?

Wel what I would do is get an old tooth brush and take out the soul first then use some detergent and scrub the stain if that doesn't work I would dip the end of the toothbrush in bleach and scrub the stain and if thy doesn't work that is one tough grass stain but if u really love those shoes and need them I would use so white nail polish or something to cover it up but don't I mean DO NOT submerge ur whole shoe in bleach that will make it smell really bad trust me the smell of feet and bleach should never meet good luck I hope ur stain comes out
