8.5 Cleaning and care
Although the surface coating of a composite aircraft is robust and resistant, always
take care to maintain a perfect surface.
For cleaning and caring the following is recommended:
o
Clean the surface (especially the leading edge of the wing panels, horizontal
stabilizer and fin) with clear water, a sponge and a chamois leather.
o
Do not use rinsing additives common in trade too often.
o
Polish and polishing materials may be used.
o
Petrol and alcohol may be used momentarily only, thinners of any kind are not
recommended.
o
Never use chlorine hydrogen (Tri, Tetra, Per, etc.).
o
The best polishing method is the buffing of the surface by means of an edge
buffing wheel, fitted to a drilling or polishing machine:
Hard wax is applied against the rotating disc or liquid wax is applied to the
surface to be polished. Then the polishing machine distributes the wax
lengthwise and crosswise across the surface.
Warning:
To avoid localized overheating, the buffing wheel should be moved constantly
o
FLEET MAGIC from Chemsearch is recommended for cleaning the fuselage
and tailplane, which are in the wake of the propeller.
Note:
Polishes, way and additives containing silicon should not be used because this
might cause additional work in case of repairs of the coating.
