>>7795577I usually take the largest foam cup I can get from the local Wawa or Sonic drive thu and add some water and dish soap. I use Dawn cus Lego is measurably stronger than baby ducks. Use a little water and add a handful of bricks. I swirl it then pour the water and soap out of the lid hole. I do a few rinses and swirls then dump the bricks on a nice beach towel. It may take a little time, but it gets them nice and clean. The foam cup will eventually die from hundreds of internal Lego cuts. Hope you do good.
