I just put it in the washer, cold, on the "extra light" cycle, and no other clothes. I was nervous because of the felt crest and numbers, I knew the jersey itself would be fine, the felt parts were what I worried about. Everything turned out fine though, it was nearly dry already when I pulled it out of the washer, the dirty areas are cleaned, the crest is perfect, still stiff, no wrinkling, the numbers are fine, colors didn't bleed or anything. Now, I wouldn't wash it on a regular basis, I've had it for a year and a half or so, and this is the first time I washed it. The only thing that sucks is that there was a small sticker attached to the tag inside the jersey, I think it was the manufacture date or something, but that obviously didn't survive the wash. Jersey turned out great though, thanks for all the advice!
