Plastic Foundation  -  the stiff kind like plasticell
 
Would like to hear from people who have used it for a few of seasons.
 
How easy is it to clean up?  (can't put it in the solar extracter)
If you put it back on after cleaning how well do the bees except it
back?
Any warping or cracking?
Can you scrap it clean with a hive tool?  Any damage when you do?
Any little tricks to handling it?
