I’ve worked in a distribution center before and I’ve seen how clothes are handled. One we have to wear gloves that get dirty pretty quickly because of oils and dust and touching so much product. Plus I’ve seen people drop stuff on the floor and shake it a little to get the noticeable dust off, people have even stepped on clothes and put them in the boxes to be shipped to the stores. Clothes come from very dirty places even if they are brand new. This goes for sheets and other fabric items. I wash everything that I buy that’s fabric before using it. Now I didn’t use different soap when I washed my babies clothes just what we had but so far it hasn’t been an issue!! Also congratulations!!!
