Curious about the shea butter -- any problems washing it out of your shorts, especially the chamois?

I've used Chamois Butt'r for years, and have no problems with it on my butt where I need it most. But recently I've had chafing with the seams in the front of my shorts. The Chamois Butt'r solves that problem, but also causes a rash of tiny red spots a couple of days later.
