How to Use
Shake concentrate well before diluting. Mix 4 parts water with 1 part concentrate (example: 4 cups water + 1 cup concentrate = 5 cups spray). Pour diluted solution into spray bottle and shake before each use. Apply as a spray or wipe-on with cloth. Brush horse to remove dust and dirt before applying for best adhesion. For face and sensitive areas around eyes and ears, apply with damp sponge or cloth. Reapply daily or as needed—may need more frequent application in heavy fly conditions or after sweating. One 32 oz bottle makes 5 quarts (160 oz), providing approximately 30-40 full-body applications.
