Colostrum leaks

I'm 38w5d and all this week I've had colostrum leaks like every hour I know it's normal just sticky and embarrassing. I pretty much walk around naked at home these days because clothes are so uncomfortable. I just wear undies and shorts and am topless but I've noticed that I'm leaking in my sleep too. Hubby is worried I'll stain sheets. Anyone know if colostrum washes out easily?
