Use dermatologically-approved detergent (e.g., Purex®, Clear®) on underwear or any other type of clothing/material that comes into contact with the vulva (e.g., pajama bottoms, exercise clothing, towels); Use 1/3 to 1/2 the suggested amount per load. Other clothing may be washed with the laundry soap of your choice.
Avoid using fabric softener and/or bleach on underwear or any other kind of clothing or material that comes onto contact with the vulva.
Avoid using dryer sheets on clothing/material that comes into contact with the vulva; hang-dry these items.
Double-rinse underwear and any other kind of clothing that comes into contact with the vulva.
If you use stain-removing products on items that come into contact with the vulva, soak and rinse them in clear water and then wash them in your regular washing cycle (given the restrictions above) in order to remove as much of the product as possible.
