I am just wondering WHY if you already know all of this, and you already know this is a lifelong question,(especially on this board), and you don't care to really hear WHY you should wash...just why did you even make this topic?
the # reason you should ALWAYS wash is chemicals...period..the rest is irrelevant..because you can always add the sizing back in to give your NEW feel, but you won't have the chemicals to contend with!
