George,
Just be very careful what you stick in the plasticene. If the item is solid and easy to clean, that could work. But don't put brushes, rakes, brooms or anything with lots of little tines or holes in it because you will never get the stuff off. Even feet are difficult to clean, and the inside of legs is impossible as well.
Poles should work fine as they can easily be cleaned. Cheers, Pgal 
thanks for the advice, i will put only vegetables in it like the round cabbages etc etc
