Section 12-30 
Unscheduled Servicing
1. General 
This Section tells you how to clean the airplane. It also tells you how to remove snow and ice from the airplane. 
2. Exterior Cleaning 
The outer surfaces of the DA 40 must be kept clean to keep the good performance characteristics of the airplane. The leading edges of the wings are specially important. 
Protect all control surface bearings and other lubricated components before cleaning the airplane. 
Use large quantities of water to clean the airplane. If necessary, add a mild cleaning agent to the water. Remove excess dirt or dead insects immediately after flight. Dried-on dirt is difficult to remove. 
CAUTION:  DO NOT USE CLEANING OR POLISHING AGENTS WHICH CONTAIN SILICONE. IF THE AIRPLANE NEEDS REPAIR, SILICONE CAN PREVENT REPAIR MATERIALS FROM BONDING CORRECTLY. 
Approximately once a year, apply a silicone-free automotive polish to the outer surface. 
3. Canopy Cleaning 
CAUTION:  DO NOT RUB THE CANOPY WHILE IT IS DRY. DO NOT USE DIRTY CLOTHS OR SPONGES. THE ACRYLIC CANOPY SCRATCHES VERY EASILY WITH EVEN THE SMALLEST PARTICLES OF DUST. 
Clean the canopy with large quantities of water. Use clean sponges and a good chamois leather which is not used for any other purpose. 
Polish dull or scratched areas using a special acrylic cleaner. Remove scratches with special polishing emery cloth (e.g. Micro-mesh). 
4. Interior Cleaning 
Clean the interior with a flame-proof vacuum cleaner.

5. Engine Cleaning 
Use a cold cleaning agent to clean the engine. 
CAUTION:  DO NOT LET THE CLEANING AGENT GET INTO ELECTRICAL COMPONENTS AND ENGINE INTAKES.  
CAUTION:  DO NOT START THE ENGINE UNTIL ALL OF THE CLEANING AGENT HAS EVAPORATED. 
Protect all electrical components and engine intakes with polythene bags or other means. Obey the cleaning agent manufacturer's instructions. Refer to the engine manufacturer's Maintenance Instruction Manual for more data. 
6. Ice and Snow Removal 
Remove snow and ice as soon as possible to prevent melted water from freezing later and causing damage.
