Dumb question from newbie. Can bike shorts go in washing machine?

[Trekhawk]

I just invested in a couple of pairs of new biking shorts and the washing directions are very vague. My Sugoi say to wash before wearing, but do not say how. Can bike shorts go in the washing machine or should they be hand washed? Thank you!!

I wear Sugoi shorts, I wash mine on the gentle cycle in cold water and then line dry.
