I just got some lovely threadless t shirts. I wore them, I sweated with sheer glee, and now I need to wash them. The problem is though that I don't have a cold wash option on my machine.

Does anyone know if I can get away with using the 40 degree cotton option without ruining them? Or perhaps delicates at 40?

Or am I going to have to handwash them everytime to protect their awesome-ness?
