Best way to strip for leaky nappies?

The nappies that I use most often have started to leak so I think they need a strip wash. Is there a method that is best for leaky nappies? Thanks

ummmm what about a tumble in case the pul needs re sealing?

Oh i hadnt thought of that, we dont have a drier but might have to take them to MILs for a spin.

annika - is that a common thing? i've got a couple of blueberry's which i *think* are starting to leak through the middle of the fabric rather than through leg gape. i thought it might be the end of their life. if it's as simple as a tumble dry, i might take them to mil's next time we're there to use her facilities. if that's the case, do you put them in the drier wet, or already dry?
