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
hypochlorite and chlorine bleach in powder form, can result in dam-
age to the protective layer of stainless steel and corrosion on compo-
nents. 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 irrepara-
ble damage.

Anti-chlorine treatment must be carried out immediately after chlo-
rine 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 thiosulfates 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 thiosulfates because hydrogen peroxide neutralizes chlo-
rine.
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.
