When you open their bag of garments you will get a strong vinegar smell. Through the print process, we use a pre treatment on our garments before printing. Once the pre treatment is sprayed and the image is printed the garment, then is sent through the dryer. The pretreatment is necessary for the ink do dry to the garment in the dryer. Once the garment passes the quality control check, they are bagged and labeled for shipping. So the smell can be strong.
Removing the smell is easy. Just was the garment inside out in cold water with a light detergent and the smell will be removed. It is not necessary to turn garments inside out. However I like to wash my new garments inside and hang to dry the first couple times.
