Chlorine and component damage


Frequent use of chlorine products increases the risk of damage to
components.

The use of substances containing chlorine, such as sodium hypo-
chlorite and chlorine bleach in powder form, can result in damage to
the protective layer of stainless steel and corrosion on components.
Therefore, refrain from using substances containing chlorine. Use
oxygen-based bleaching agents instead.
If, however, chlorine bleaching agents are used, an anti-chlorine treat-
ment must always be carried out. Otherwise, both the washing ma-
chine components and the laundry may suffer persistent and irrepar-
able damage.

Anti-chlorine treatment must be carried out immediately after
chlorine bleaching agents have been used. Hydrogen peroxide as
well as oxygen-based detergents and bleaching agents are suitable
for anti-chlorine treatment. The suds must not be drained in between.
Treatments with thiosulphates can result in gypsum-like deposits par-
ticularly when used in combination with hard water. This gypsum can
build up in the washing machine or cause incrustations on the laun-
dry. Treatment with hydrogen peroxide is recommended over treat-
ment with thiosulphates because hydrogen peroxide neutralises
chlorine.
The exact dispensing quantities and the treatment temperatures re-
quired must be set and tested on site in accordance with the dis-
pensing recommendations of the detergent and cleaning agent man-
ufacturers. The laundry must also be tested to check whether it con-
tains any active chlorine residues.
