I used seafoam F.I. cleaner. put a little bit in the top of each injector to "break them loose" then soaked them overnight in my parts cleaner. then the next day installed them back in the rail. Then filled my pressure cleaner with seafoam and a little fuel, up to 55 psi and then fired off each injector manual until i got a good pattern. put them back in and it fired right up and ran. I hope that answered your question.
