Normal WC units, bidets and wash basins have a glazed
surface. Glazed surfaces are easy to keep clean and
are resistant against most chemicals. Clean regularly to
prevent cleaning problems. Use normal cleaning agents.
“Clean regularly to prevent cleaning problems. However,
avoid using cleaning agents on the flush button, instead,
use hot water and soap and wipe dry with a cloth”.
This is because cleaning agents for porcelain are not
intended for chrome parts/plastics and can risk cracking
the flush button if used frequently.
Cleaning utensils, which contain abrasive agents, such
as wire wool and green scouring pads, must not be
used. Strong acids, e.g. hydrochloric acid and sulphuric
acid and strong alkalines, e.g. caustic soda should not
be used. Dripping taps and running WC units must be
repaired immediately.
For repair or to purchase spare parts, contact a
plumbing contractor or plumbing centre. They can be
found in the Yellow Pages.
In houses that are unheated during the winter, the WC
unit’s flush cistern must be drained and dried out. Pour
3-4 decilitres of anti-freeze into the water trap and cover
the water mirror with cooking oil or cling film to prevent
evaporation.
