STAR SAN is a blend of phosphoric acid and dodecylbenzenesulfonic acid. This synergistic blend provides a unique killing system that is unaffected by excessive organic soils. STAR SAN is also a selffoaming sanitizer. It can be applied through a foamer to produce self-adhering sanitizing foam for external sanitation. STAR SAN is also an excellent sanitizer for hand application. Sanitizing with STAR SAN on a daily basis will leave equipment in a acid condition that will eliminate water spotting. It is not recommended to use STAR SAN on soft metals because of the acid nature of this product. Directions: A dilution of 1 ounce to 5 gallons of water, STAR SAN will provide 300 ppm of dodecylbenzenesulfonic acid. After 1 to 2 minutes contact time, drain sanitizing solution equipment thoroughly. Do not rinse. If using Star San in CIP, proper water balance must be maintained or your pump may cavitate. If used at a rate of more than 300 ppm, a potable rinse is required. Part Soaking: Use 1 ounce of STAR SAN per 5 gallons of water. Parts must have contact with solution for 30 seconds and put on wet. When solution begins to cloud, sweeten with Star San or Phosphoric Acid. Solution must remain at a pH at 3 or below to maintain proper sanitizing level. Hand Utensils: Scrape or preclean dirty utensils. Clean using a suitable detergent, following label directions. Rinse with potable water. Soak or spray utensils/inflations with a STAR SAN ACID SANITIZER solution (1oz./5 gal. of water). After 1 to 2 minutes contact time, drain solution thoroughly. Prepare a fresh solution daily or more often if the solution becomes soiled or dirty. Bulk Milk Tanks: Clean tank with a suitable detergent and rinse with potable water. Manually spray a STAR SAN ACID SANITIZER solution (1 oz/5 gal. of water) on all surfaces to be sanitized. After 1 to 2 minutes contact time, drain solution thoroughly. Food Plant Use: Bulk Tanks, Vats and Utensils: Scrape or preclean dirty surfaces. Wash equipment with a suitable detergent and rinse with potable water. Sanitize with a STAR SAN ACID SANITIZER solution (1 oz/5 gal of water) by either brush soak or spray method. After 1 to 2 minutes contact time, drain solution thoroughly.
