IDD recommends that the chlorine "low range" (0.05 to 16ppm) tube be used to monitor gas levels. These tubes
readily detect and measure all types of inorganic chlorine.
Uses In Brewing
The brewing uses for stabilized ClO
Malthouse:
Stabilized ClO is an effective wash-down sanitizer for walls, floors, germination areas, and steep tanks. At 100
2
to 500 ppm it will kill and bleach out mold and mildew common to these high-humidity areas. Stabilized ClO
been successfully used in barley steep waters to inhibit microbial growth of all types. Typically at 10 to 50 ppm,
depending on the microbial load, one can assure a safe re-cycling of the steep water into subsequent batches.
Stabilized ClO 's strong oxidizing capability actually reduces B.O.D. loads for disposal.

Brewhouse:
Safe for all vessels and piping systems, whether copper or stainless steel, stabilized ClO
free environment in coppers/kettles, mash filters or lauter tuns, swirl tanks, settlers, and wort cooling systems
when used at 50 to 100 ppm. The related piping systems for wort transfer to fermentation areas can be sanitized
at 100 ppm. It is also safe to leave a 50 ppm solution in pipelines to keep them sanitized during periods of non-
use.
Fermentation/Storage Areas:
A 50 ppm solution is adequate to sanitize tank walls and related piping systems. Since low levels of contact with
finished product do not effect final beer flavor, brewers can safely use stabilized ClO
to obtain some residual bacteriostatic value. It is recommended that boots, gloves, yeast-handling tools, and the
like be sanitized at 100 ppm. Stabilized ClO
Filtration:
Stabilized ClO is particularly useful for stabilizing and sanitizing filter systems. It can be used to shock-sanitize
2
activated carbon and sand/gravel filters in water treatment facilities. Typically, a 50 to 100 ppm solution is run
slowly through these type filters. Stabilized ClO
bed is sanitized it is then possible to dose Oxine into the water stream, prior to the filter bed, at a concentration
of 1 to 5 ppm in order to prevent future contamination.
Plate-and-frame filters can be sanitized with a 10 to 50 ppm solution without the typical water flush/rinse required
by acid-sanitizers and the like. A standing solution of up to 10 ppm can be left in a filter during periods of non-use
with no harm to the filter frame or the sheets. A solution of the same strength sprayed over the outer exposed
edges of the filter sheets will prevent mold growth when standing. It is recommended that this procedure be
carried out after any normal beer filter use to inhibit the growth of yeasts and bacteria, since residual beer on the
sheets makes for an ideal growth media.
Active Carbon Bed (ACB):
Infected ACB's can be back-flushed and soaked in a 100 ppm solution of ClO
time a forward flush-out of 15 to 30 minutes with the process water can take place. It is then advisable to inject 1
to 3 ppm of activated ClO
Packaging:
•
Stabilized ClO provides a safe sanitization and soaking solution for keg washer rackers, bottle
2
fillers, and can fillers. Sanitize at 50 ppm and soak or stand filler bowls in cold water at 10 ppm
•
To enhance beer flavor, use 20 to 50 ppm of stabilized ClO2 as a final cold rinse for aseptic keg,
bottle, and can rinsing, immediately prior to filling
•
The use of stabilized ClO
effective at 10 to 20 ppm as both a sanitizer and microbial preventative

Stabilized ClO is most effective in the moderate temperature zones (warm-up and cool-down fresh
