4.1 General information

about roof cleaning
The best cleaning results are
obtained in the evening in au-
tumn/spring where fouling on
the roof is in growth.
If the fouling is very dry it is
necessary to apply pure water
to the roof before cleaning and
wait 0,5-1 hour before applying
the detergent. This can be done
by removing the detergent hose
from the detergent canister.
Adding water is to ensure that
the pores open and the fouling
can thus be affected by the de-
tergent.
Depending on the degree of
the fouling, it may be necessary
with an additional treatment
after 2-3 months.
The Nilfi sk detergent causes
only harm to plants when large
amounts of detergent are ap-
plied.
Do not stand on
the roof or on a lat-
ter when cleaning.
The Roof Cleaner is
made for safe ground operation.
For better control of the hoses 4
hose clips can be mounted.
If the gutter of the house is con-
nected to a rain water collection
system, make sure that the
detergent is not collected but
disposed in the right way.
The detergent kills the fouling
but does not remove it. This is
done via rain, wind, etc that with
time will fl ush the fouling into
the gutter.
The result of the decomposition
of the fouling can, depending on
the conditions, be seen after 4-6
weeks. Full effect can be seen
after 4-6 months.
When applying the detergent to
the roof, please observe that the
detergent is not directed under
any roof tiles as this may cause
damages to the house.
Wind will affect the direction and
the length of the jet. Best result
is obtained when cleaning is
done on a day with no wind.
Wear goggles,
protection gloves
and clothes to en-
sure that your skin,
eyes, etc do not get in contact
with the detergent.
