I recently bought a sifter from the Williams Sonoma outlet -- the kind with the spring loaded handle that you squeeze. I loved it, but we don't have a dishwasher and a few clumps of flour/sugar/etc. got stuck in between the mesh layers and would not come out. I tried everything -- soaking it in boiling water, scrubbing it, but it was just trapped and eventually got pretty gross (and rusted from all the soakings). So I want to replace it, but need suggestions for sifters that are easy to hand wash.
