Hi everyone,
John thanks for the link, but it is not what I am looking for.
I am aware also about Service Masters rules and regs, but hey, some one out there may break it

The product I am looking for is a chemical called 'Wall Glide' This is brilliant stuff and comes in a 10 gallon container I think.
It is used mainly in restoration work (fires) and will remove any kind of soilage of walls and paint work, without damaging the wall covering (if used correctly).
The reason I require this, is for some smoking rooms, this stuff cleans the nicotine of the walls etc in seconds.
Many Thanks
Andrew
