Man real talk
Get you one of them big cups from burger king....fill it up wit hot water, bleach and laundry soap....drop the laces in it and get you a old toothbrush to move the laces around in the water. after you do that for a lil bit take the laces and scrub the brush on the areas that did not get clean...trust me it works!
fu*k THAT..........u get a big a.ss cup fill it with hot water and get some oxyclean......put the oxyclean in the water and mix it up....throw ur laces in there and mix them around for a few minutes then leave them in there for like 15 more minutes.......then rinse them off and they should be fresh white again
