Initial Cleaning: Soak resin bed in 8% by weight solution of
Inhibited Citric Acid 3109 for 4-8 hours. Back wash resin bed
thoroughly and regenerate softener. For severely fouled resin beds,
increase soak time to 12-24 hours. A second application may be
beneficial for improved iron removal.
Preventative Maintenance Cleaning: Add 32 ounces of Inhibited
Citric Acid 3109 to the brine tank for each cubic foot of softener
capacity every 8 to 10 generations or as iron fouling demands. For
additional information on product application, contact your industrial
Loop Cleaning: Dosage will vary depending on severity of

further application information.
