Cleaning
Maintenance
Use a mild household cleaner to clean the window
frames. Washing petrol (not car petrol) helps against
stubborn dirt. Under no circumstances should you
use scouring agents or solvents, as these attack the
surface of the frame.
If the window squeaks when opening or closing,
it is sufficient to apply a drop of resin-free
household oil to the moving fitting parts. We
recommend that you carry out this maintenance
yourself at least once a year. This will ensure that
your windows are always easy to operate.
Windows
Cleaning the window sills
The window sills should only be cleaned
with a damp cloth and a mild cleaning agent.
Scouring agents and brushes will scratch
the surface. Vinegar-based cleaners are also
unsuitable. They leave stains on the window sill
that you cannot remove afterwards.
Checking the seals
Check regularly whether the window seals are
still elastic, undamaged and properly tightened.
Only then can they keep out draughts and water.
To prevent the material from becoming brittle or
permeable to water, we recommend rubbing the
window seals with Vaseline once a year.
Drainage openings
When cleaning the windows, remember to also
clean the drainage openings in the frame and
the rain rails. If dirt accumulates there over a long
period of time, the water can no longer drain away
and, in the worst case, it leaks into the home.

If a window casement grinds or can no longer
be opened or closed without problems,
it must be repaired.
