So, you've put your sneakers in the washing machine...they're looking all pimp...but your laces are really grubby and gross (don't put your sneakers in the washing machine with laces in them). To get sparkling white laces you'll need, hot water and a bar of soap...easy. Put your grubby laces in the hot water for a minute, then put both laces in your hands with the bar of soap...rub your hands together almost like your washing your hands...do this for a few minutes then take the soap out and scrub the laces together...put the laces back in the sink for 10 minutes, remove and voila...you should have super white laces x
