Problems with residual static electricity after protective film removal from construction panels

My Name is Simon McCartney, I am currently working with a large construction company that specialises in metal and glass facades. We have a particular problem with indoor facade projects, such as the new Delhi Airport we are working on now. The metal panels are transported and installed on site. They are covered with a protective film which is applied electrostatically. So Far so good.
Towards the end of the project we will have to remove the film. It is inevitable that the site will be dusty inside at that time.
When we were working on Hong Kong Airport we did the same and the panels became heavily contaminated as if they were 'sucking' the dust into the paint. Cleaning was a nightmare.
This does not happen with external facades. How can we solve this problem, is there some special steps we should be taking to remove the residual static charge (I assume that is the problem).
