If you happen to get a lot of Sweet Sweat on your clothing, it's best to wash your clothes shortly after use, as opposed to allowing them to sit with Sweet Sweat for an extended period of time.   Sweet Sweat contains oils, and may build up in certain fabrics. However, this can usually be remedied by doing a light scrub of the affected area with detergent or stain remover like OxiClean or Shout. If oil has built up in the clothing over time, we recommend soaking the clothing in hot water for 10 mins, pulling it out and applying a dish soap (Palmolive, Ajax, etc) that is meant to break down oil to the affected area and brushing lightly with a toothbrush or laundry brush. This is followed by a rinse in hot running water which will loosen and remove the oil. We generally recommend wearing loose fitting clothing when using Sweet Sweat, simply for the fact that the product works best when on the skin, and tighter clothing absorbs a good percentage of the product off the skin. It’s good to keep in mind that Sweet Sweat can make you sweat more— so it’s best to not wear brand new or expensive clothing, or clothing you don’t want to sweat in.
