Homebrew PCBs

Hi Tom -

    About 25 years ago I made a small number of silk screened PCB's at 
home. I would like to start making a few PCB's again with this 
process. I have forgotten the little bit I knew then, so I have many 
questions.

    Someone recently let me cart off some 50 silk screens with PCB 
patterns (all unidentified); they are up to 2 decades old. How can I 
clean these for reuse? Household bleach and water rinse?

   What photosensitizer would you recommend? The simpler for home use, 
the better.

   Will PCB patterns laser printed on transparency work for making the 
screens?

    I am interested in a step-by-step "cookbook recipe". I did buy a 
book by Kosloff on "Screen Printing Electronic Circuits," but it is 
fairly general. I look forward to hearing from you.
