Best Way to Sanitize Smart Pots/Grow Bags?

I've got 10 5 gal. smart pots that have been used once. I had a spider mite problem, so I'm trying to be as thorough as possible when it comes to cleaning and sanitizing everything!!!! I thought about rinsing them out well, then putting them on a short cycle in my washing machine with diluted bleach, but I'm afraid they'll fall apart.

Anyone got a great way to do this?

Thanks!

You can definitely stick them in the washer

I take them to the local laundromat and use the industrial washers as not to destroy my home one.

Solarization!

yea throw em in the washer, no bleach though. i just used a little detergent i had a mite prob too. the detergent kills the little fuckers. wash cold or some of the bags shrink

Yep. Washing machine all day. They soften up a good bit, but work just the same after cleaning.
