From: homeroast-admin [mailto:homeroast-admin] On Behalf Of Sandy Andina Sent: Monday, July 17, 2006 7:47 PM <Snip> fast--often, even after a Cafiza-and-steaming-water soak for half an hour, I need to ream the screen holes out to dislodge the residue. <Snip> Interesting and not good. I've never had the inside of the screen get gunked up in almost 5 years, not with Silvia or the Bric'. What I was referring to on the Bric's screen holder walls, are literally inner vertical side walls not the horizontal screen itself. And it was minor gunk on the walls at that, screen itself clean as a whistle both sides. (the E61 screen assembly looks is like a cylinder with the screen on one end, a flat bottom straight sided bowl with about 3/4" sides) Silva's almost all flat screen assembly never had a build up at all. If following good post shot cleaning hygiene screen shouldn't get gunked up. Do you flush the group after EVERY shot? In addition to group flush I follow with quick PF backflush blank flush wiggle after ever shot. So it's open group flush a couple seconds and PF backflush blank flush wiggle couple seconds, after every shot. And then water only backflush after every shot session completed, even if it's only pulling one shot. Combined with weekly Cafiza detergent back flush screens have never gunked up, never. Also, if entertaining pulling lots of shots I detergent backflush end of day (or next morning) regardless if detergent backflushed the week or day before.
