How to clean plastic pots to reuse?

[elaines]

Hi!

I have several orchids (some of which are actually growing! ) and need to repot most of them. I've found that clear plastic pots work best for me for various reasons and would like to reuse some I have on hand (esp since they're expensive to order & impossibly to find locally ). Can plastic pots be cleaned sufficiently in the dishwasher? Are there better ways to clean them (that don't involve Physan or other chemicals toxic to curious cats) or other things I should do in addition to using a dishwasher (if dishwasher's okay)?

Thanks a bunch!
