I also just read the guide posted on the Flat Out Containers.  It is very easy to wipe those water droplets off out of the dishwasher.  Flat Outs can be washed completely flat in the dishwasher to save room and they come completely clean.  Please dont blame Tupperware or give them a bad wrap for neglect.  My kids leave stuff in my tupperware all the time and sometimes it gets left in inconspicuous places and they are nasty when you finally find them.  That is not Tupperware's fault.  Flat Out's ROCK I have sold many of  them and gave them to family and friends, probably 100 of them and I have had NO complaints from my family, friends or customers.  TUPPERWARE is THE BOMB!!!!!!!!!!!!!
