Hello ladies, I'm sure one of you has the answer for me.

Erik just got a brand new Merino wool Icebreaker shirt in his race packet but he dropped it on the bike and it has fresh grease all down one side. It is a red, IcebreakerGT 150 ultralite in case that matters.

When I get grease on a cotton shirt, I just rub some butter or lard into it (who has lard anymore??) until the black grease disappears, then I hand wash it with warm/hot water and soap, then throw it in the washer and the grease is always gone without any stain (not even from the butter), but I'm afraid to try that with Merino wool.

So - does anyone have a tried and true method to remove fresh bike grease?

Thank you!!!
