Mark Says: I've experimented with pressure washing (the primer cups/anvils) enough to know I'm going to work it (a pressure washing session) into my primer cup work-flow. Exactly how is a work in progress. I Briefly browsed Amazon for a few products that may help us but these products are largely unknown. Screens 20 Mesh (6 pack screens) $6: https://a.co/d/4i3hGAG Screen 20 Mesh Roll $14: https://www.amazon.com/dp/B0BYCJ3RK7?ref_=pe_125775000_1044873430_fed_asin_title&th=1 Steve S says: I can confirm 20 mesh does capture 1mm SS pins. Mark Says: A Beer hopper of this small mesh may not release the water quick enough to be used in a pressure washer scenario. Beer hopper strainer (300 Micron) $12 (18cm x 7cm) https://a.co/d/8aqVbTU --- Mark Says: Is a tea strainer big enough? Tea bag strainer/filter $12 3.15"L x 3.15"W x 3.15"H https://a.co/d/dl5HfoS And a pressure washer And warmer weather May make quick work of cleaning primer cups and de-anviling at the same time. Elmer Says: I'm going to try the following outer shell and line this cage with #20 mesh Grill tube: https://www.amazon.com/dp/B0C7VJCDRS?ref_=pe_125775000_1044873430_fed_asin_title Mark Says: I'm working with Elmer and following his lead on this one. I've ordered and received both the grill tube and the #20 mesh. Plans are currently to line the outside of the grill tube with the mesh. Capping or ensuring the ends aren't blown off with the wand. Pressure wash the cups and anvils for approximately 2 to 4 mins. I'm hoping to shake and bake for another 2 mins (4 mins tops). Inspect the de-anviled cups and if the ratio is unsatisfactory then I'm going to add ss pins and pour scalding hot water through the cage and give this heated mass a last shake and bake.
