Rag Top Help

Yeah so I guess I erased my first topic I posted or something. I have a few questions for you guys.

I got a used ragtop in good condition and it's just a little dirty. Whats the best stuff to use to clean it? It's black canvas

What can I use to make a template since I don't have one?

Did anyone get install part from streetbeat after they bought them? Like get like replacement parts?
