I'm the kind of person who puts off washing my running clothes for as long as possible. In part it's because I'm lazy, in part because I have to lug my laundry to the BF's to use his washer/dryer because I'm too cheap to pay for my laundry and in part because I have my favorite/most comfortable running outfit and I want to wear it all the time and if my tights are hanging out to dry, I can't wear them. So needless to say, when Penguin Sport Wash sent me their detergent to test, I waited until I really couldn't stand the stench of my Under Armour or the salt that was starting to get caked to it (True life how nasty is that?) before I washed it. In my normal laundry habits, I usually use whatever the boys have in their house detergent wise. That could be Tide, Oxyclean, generic drug store stuff, whatever. It all seems to work fine and I've never noticed any negatives, but I was excited to try the new stuff. So I dumped my Under Armour in the wash along with all my other clothes (everything in one load on cold...I told you...lazy at laundry) dumped in the Sport Wash, which had no scent. I sniffed really hard to see if I could smell anything but couldn't -- a good sign. When the load finished the first thing I did was smell my Under Armour, which before going in the wash reeked. Seriously, it was gross. But when it came out I smelled nothing. No lingering B.O., no funky detergent scent, just a lot of nothing. So this stuff definitely works, but it is pricier than my normal detergent (yes, sometimes I buy the boys stuff so I have it to use). When I strike it rich or win millions in the lottery and it fits better in my budget, I'd definitely consider using it again.
