Chlorine and component damage
Frequent use of chlorine products increases the risk of damage to components.
Notes on using chlorine bleach
The use of agents containing chlorine, such as sodium hypochlorite and chlorine bleach in
powder form, can damage the protective upper surface of stainless steel and cause corro-
sion to components. Factors affecting this are chlorine concentration levels, contact time,
and temperature. It is therefore advisable to avoid the use of such agents. Oxygen based
bleaching agents should be used instead.
If you still need to use chlorine-based bleach for specific soiling, you will need to perform a
neutralizing step each time. If this is not done machine components and laundry can suffer
irreparable damage.
Antichlorine treatment
Anti-chlorine treatment has to be carried out immediately after chlorine bleach has been
used. The use of hydrogen peroxide or an oxygen based cleaning or bleaching agent is
recommended and the laundry should not be drained in between.
With thiosulfate, especially when used with hard water, gypsum can form, which can lead
to incrustations on laundry or deposits in the machine, on the laundered items or a build-
up of deposits in the machine. The use of hydrogen peroxide is preferable as it aids the
chlorine neutralizing process.
The exact quantity of additives and the treatment temperatures required must be set and
tested on site in accordance with the dosage recommendations of the detergent and addi-
tive manufacturers. The laundry must also be tested to check whether it contains any ac-
tive chlorine residues.
