OUR REFRESH SPRAY WAS CREATED TO EXTEND THE TIME BETWEEN DENIM WASHINGS.  WHEN TO REFRESH? WITH RAW DENIM THE FIRST SIX MONTHS WITHOUT LAUNDERING ALLOWS THE DENIM TO MOLD AS YOUR PERSONALIZED WEAR-PATTERNS ARE SET.  I WOULD RECOMMEND REFRESHING PERIODICALLY DURING THIS PERIOD.  I LIKE TO THINK OF IT AS "FEBREEZE FOR YOUR DENIM" BUT WITH A WOODSY, THERAPEUTIC SCENT.
