Your linen will be returned to you in 3 categories: (i) clean, (ii) stained, and (iii) discard. We ask you to set aside the stained linen until you have at least half a bin. Once you have accumulated at least half a bin, send it back to us for rewash processing. The rewash process has more aggressive process parameters and a stronger proprietary chemical blend. We do everything we can to get those tough stains out so you can extend the life of your linen!
