So I have a Nike Summit White Sport Loop and get dirty a little easy. Found the best way to clean it without damaging the band. Tide cold water and a little Allen's vinegar. In a larger than a cereal bowl, add a teaspoon of tide and a little cleaning vinegar and fill the bowl with cold water (make sure to use cold water, hot water will mess up the tape cause of the elasticity). Use an old toothbrush to massage the sports happiness to get that soap. I let myself sit overnight. In the morning, I massage the tape again and then rinse under cold water and rinse the toothbrush and massage the tape under the water to get any extra soap. The band looks new and is not stretched, still feels cramped like new. Used a towel to dry and let it air dry the rest to dry.
