Calling all Country Save users...

I'm trying to find out if Country Save works. I have all pocket diapers. I used Sun Ultra, but got horrible buildup so I switched to Tide. I know this probably isn't the best switch, and it's just a matter of time before I'll be dealing with repelling issues, so I've been looking at more "residue-free" detergents. Country Save is the only one that I can find locally, so I just want to know peoples' opinions of it.

If you've used it, how does it compare to other detergents you've tried?

If you've used it on pocket diapers (or even if you use other types of diapers), have you had any buildup issues with it?

Thanks!
