The assembled Ant Barrier has been tested and proven dishwasher safe. The pressure sensitive material on top of the Collar is rated for an extremely strong bond and is for PERMANENT attachment to the Food Holder. 

We have tested the Ant Barrier with home dishwashers and Industrial dishwashers as well.  Industrial dishwashers are run at higher temperatures.
