3-Compartment Sink Sanitizer Dilution
Fluid ounces of chlorine, quat, or iodine concentrate to hit a target food-contact ppm in a sink compartment (oz/gal = 128 x ppm / (active% x 10000)), flagged against the FDA Food Code band. Cold or alkaline water needs more chlorine; confirm with test strips.
Formula and source
oz_per_gal = 128 x target_ppm / (active_pct x 10000); total_oz = oz_per_gal x batch_gallons.
FDA Food Code Sec. 4-501.114 sanitizing-solution concentrations, by name.
