Your Sweaty Workout Accessories
You could run your sweat-stained running hat through the washing machine, but even on the gentle cycle, the agitation might warp the brim. Instead, try the dishwasher. Dana White, who writes about cleaning at ASlobComesClean.com, puts baseball caps and visors on the top rack, secures them in place with clothespins, and uses the machine's longer "Sanitize" setting (even if yours doesn't have that option, the hat will come clean in a regular wash). You can use regular dishwashing detergent, as long as it does not contain bleach. When the cycle is finished, White puts hats over pitchers or small bowls to dry.
