Looking for advice.

Hi,fellows

Greetings to all

Who could tell me that if the aircraft exterior surface was not clean, how can you solve this little problem!How many times will the aircraft be cleaned a month in normal level!?

Thanks in advance before your kind reply!:ok:

Do you mean physically clean, or aerodynamically clean? One applies to dirt the other to drag. Enough dirt can of course produce drag as well.

I mean physically clean.

Use manpower or robert to clean the extirior face?

If you're not able to make it shine, it's usually because of the paintwork, which does not look nice when it is covering another layer of paintwork underneath, or if it was not re-sprayed at the overseas manufacturer. Even mechanical polishers with high grade polish does not work a new shine. I have seen this problem in China before - maybe yours is a similar problem.

Thanks in advance! ReverseFlight;)

It's very kind of you!

Before the polishing work, how do the mechanical engineers clean the exterior surface? I want to say whether the pH value of the cleaner is critical to the aircraft body！Our cleaner on hand is almost neutral...:confused:
