chocolate buttercream stain on white shirt

[TreeDweller3]

I have tried all sorts of things but I can't get rid of it completely. I've let it dry in the sun for sages, I've washed it several times...and it's still there; faint, but noticeable enough so I can't wear it.

Can I bleach it? It's 100% cotton and white. If so, how do I do it? Presumably I don't use neat bleach - what's the bleach to water ratio and how long do I soak it for? Thanks!

I managed to find a solution, for those of you who might be in the same situation. Lemon juice! Let it work for half an hour, then wash the stain with Fairy liquid and that's it! Magic!

I just came on to say Yum!

But thank you for the tip as well.
