To remove the dirt and hair from your browband, spray it carefully with a can of compressed air computer dusters (such as Dust-Off). Then polish with a lint free cloth. If the browband is used daily on your bridle, keep the bridle covered either by putting it in a bridle bag or putting an old pillow case over it to keep the dust off.  I use my browbands everyday in training and keeping them covered makes a big difference.  They stay looking new, sparkly, and fresh everyday!!!!
