CAUTION: Never use any of the following products on the aircraft:
• Trichloroethylene
• Carbon tetrachloride or similar hydrocarbon chlorides
• Any product containing silicon
Canopy
The canopy must be protected from scratches. Always wash off dust by
using liberal amounts of water with a soft chamois, taking care not to
allow dust to get between the chamois and the canopy surface. Dry with
a clean chamois. The canopy can be polished with a non-abrasive
canopy polish with a rating of 5000 grid or higher.
Never clean the canopy with acetone or lacquer thinners as this will
instantly create micro-cracks. Contact an M&D representative for
recommended canopy polishes.
Cockpit interior
The inside of the cockpit can be cleaned with mild soap and water.
Water tanks
The aircraft should always be stored with the wing tanks open to
ventilate. It would be ideal to also install a small electrical fan on top of
the wing surface over the water filler hole to force the ventilation of the
tank. This will allow the structure to dry completely and prevent any
issues due to moisture absorption.
The O-rings on the water tank filler caps must be replaced if they start to
age and crack. If the wing valves leak, the most probable cause is foreign
matter below the valve seal and sealing ring. Wiping the area may solve
the problem. The valve seal may also be cracked in which case a
replacement can be obtained from the manufacturer. The seal can be
replaced with some difficulty without removing the valve mechanism.
