Most glue suppliers recommend chemicals and methods for removing the product from stencils. What does yours suggest? Further, search the fine SMTnet Archives for background discussion.

Can you tell me a little bit about the Zestron product. How many stencils do you clean and much Zestron do you use per month? What is the cost? Do you mix it with water? If so, what temperature? How do you get rid of the waste? Thanks. Kerry
