cleaning a soft top and window replacement

[Tim Putland <tputland@charter.net>]

I would like to know what people use to clean their soft tops. 

One of the tops I have was stored in a "work in progress basement" and is 
covered in a sawdusty type filmy layer. What is my best bet to try to clean the 
windows and the rest of the top?

Also, can the non-zip out windows be replaced easily? Or at all?

Thanks
