This is a recipe for home made fursuit spray for disinfecting with a nice scent.
Use it as you would any other disinfecting type spray and enjoy the benefits of a scent of your choice! Be sure to get a fragrance oil that is "skin safe"
Don't add more drops of fragrance oil without first testing your combined solution on a towel or fur scrap to see if you like the scent strength, too many drops can get strong fast. If using a tiny bottle start with few drops only. And if your suit has airbrushing take normal precautions (spraying on the inside yanno?)
Please be aware I come from a background of well over a decade of experience with washing and taking care of costume items, this isn't a replacement for washing your costume after you get home from your event. Tips for washing can be found here: http://matrices.net/washing.asp
