i've noticed that at the 6 month mark my white syr #6 is looking pretty grimey. for background: i train in it once a week (it's in rotation with 2 other white gis). i wash it after every single wear with tide and/or oxyclean, in cold water, hang to dry. i have a white manto and a white mizuno as well. both are between 3-6 months older, and are also worn once a week (tho, obviously they've seen a lot more action, given that they're older). while of course subject to the normal amount of greying (esp at the knees and sleeve cuffs), both of them look a lot newer than my syr. they get washed and dried exactly the same, and with the same frequency, but have seen significantly more usage. both are about 50% whiter overall than my syr. could this have something to do with the type of weave? anyone else notice this, or am i just unlucky? i'd try bleaching it but a) don't want to fade the grey trim or embroidery, and b) don't want to weaken the fabric. there's a guy in my gym who bleached his, and it's obvious cuz the grey trim on the side vents is faded and almost pink-grey. also, don't get me wrong -- i know white gis will get grimey over time. that's just how it goes. but this gi seems to hang on to every little smudge it gets, whereas the same types of stains on my other gis wash out cleaner. any tips for whitening a gi without bleach? is this somethign a drycleaner could do?
