The Best Detergent for Workout Clothes Is a Century-Old Soap Bar

So Fels-Naptha remained a part of my laundry tool kit after graduation, even as recently as this weekend. (Chocolate sauce, white pants; I don’t want to talk about it.) But I only recently figured out my favorite use for it: washing workout gear. I’ve always found myself running out of athletic clothes before it was time to do laundry, and I don’t think it’s just me. (I’ve been told that owning enoughsports brasto make it between loads is essentially impossible.) When I started running more seriously a few years ago, this minor annoyance became a bigger problem. The solution? Since Fels-Naptha is just a bar like Irish Spring, I’ve started leaving it in the shower. Once I’m done with my normal post-run rinse-off, I give the clothes a quick scrub with the soap, roll everything around for a few seconds, then hold them up to the shower head to wash the suds out. The whole process takes less than a minute, and the next day, I have dry, sweat-stink-free clothes ready to go. I’ve been able to get rid of all the shorts and tops I sort of hate, and can always run in clean clothes without needing to drop rent-scale money on new gear. Now, I just need to be better about instructing my houseguests on which soap is for people.

Writer Carson Griffith swears by the Lestoil her mother introduced her to: “My only hope to remain somewhat presentable between keg parties and study sessions was my mother’s original go-to. Here’s a pro tip: Lestoil works wonders even when you don’t have time to do laundry. Rubbing some of that caramel-colored oil on a stain can get rid of it without a wash.”

Writer Maxine Builder usesSpray ‘n Wash Pre-Treat Stain Stickto clean her clothes: “Immediately after a stain happens, I rub the product onto the spot and the fabric, and let it sit for as long as possible. Before I go to sleep, I’ll wash the product out in the sink with cold water, wring it out, and let it dry. When I wake up, the stain has lifted and the clothing is ready to wear again, with no one the wiser.”

Writer Sadie Stein washes her expensive delicates with thisJapanese washbasin: “I like to put my unmentionables to soak with a littleWoolite, orForever New, or if I’m feeling flush, theLe Labo–perfumed Laundress detergent; soak them overnight; and then give them a good swish and rinse. And its washboard, of course, is for cleaningunderpants(or as some men like to call them, ‘panties’). I imagine if you were wanting to wash up any evidence of a murder, it would be very useful, too.”
