Steelhead recommends using STAR BRITE bottle wash detergent as the cleaning agent for their washers. It’s non-hazardous, economical and non-foaming, making it suitable for use in high-pressure washers. It cleans polycarbonate, PET, copolyester, and PVC bottles without leaving residue and removes ink from standard ink jet date coding equipment. STAR BRITE has three times the lifespan of bottles cleaned with caustic solutions and excellent rinsing properties, leaving bottles sparkling and reducing drag out. Recommended concentration for spray washers is 1-2% and for dip tanks, swabbing, or brushing it’s 2-4%. Cleaning with STAR BRITE should be followed by a potable water rinse and a sanitizing rinse.
