If you cloth diaper, how often do you strip your diapers, and what is your process for stripping them?

We've had a few leaking issues lately with our diapers, and I'm pretty sure that at least a few of our diapers are actively repelling water, so I'm stripping them right now. I'm not exactly sure why our diapers are repelling, b/c I follow all of the washing and handling instructions very carefully. We've been using our diapers for 10 weeks now though, so I figure it's probably time to strip them anyways.

I added a tablespoon of Dawn dish detergent to our wash, and now I'm running the diapers through a clear hot water wash 3x to wash out all of the built up detergent. What do you do?
