As the summer heats up, Sarah and co-host Adrienne Martini welcome two guests to talk about sweat. First up is Melissa Elfers, a textile scientist (who knew!), who explains the ins-and-outs of polyester, bringing the “Saturday Night Fever” white suit and Play-Doh Fuzzy Pumper Barber Shop into the conversation. Elfers explains why washing workout wear the wrong way repeatedly compounds the stink-factor, and she shares laundry tips for keeping gear fresh. Next up is Cathy Horton, creator of SweatX sport detergent. This triathlete and mom of two (including a professional soccer player!) tells how stains and stink drove her so crazy, she developed the stink-banishing detergent. Find out why Cathy calls a sweat droplet “a big rot fest,” and how perspiration makes running clothes smelly. Germ-phobes might want to sanitize their earbuds after listening to this grimy-yet-enlightening episode!Learn more about your ad choices. Visit megaphone.fm/adchoices
