GOLD-BLOC™ IS AN EXCELLENT AID FOR CONTROLLING MASTITIS. DIRECTIONS: Immediately after milking, dip each teat in undiluted GOLD-BLOC™ barrier teat dip. Teats should be dipped to the base of the udder. If the dip becomes visibly dirty or contains sediment, replace with fresh solution. At the end of lactation, the teats should be dipped with GOLD-BLOC™ for four days after the last milking. Teats should be thoroughly washed and dried before milking. Use potable water, a suitable cleanser and individual paper towels to remove the barrier and to prevent contamination of the milk. Do not use for cleansing or sanitizing milk equipment.
