I had to strip my ones once. You will probably find a thread on stripping in the cloth nappy area.
It's something like
-Hot wash
-cold wash with vinegar and baking soda
-cold wash with vinegar
-cold wash
I just did mine by hand in a bucket and chucked them in the last rinse cycle with my clothes. Then hung them up in the sunshine.
Also, I find my thicker ones get a bit funky smelling when they don't get completly dry so I often leave them in the hot water cupboard overnight.
ETA, once I tried washing them with Am-O-Lin which is what I use on Jody's nappies. I don't know why but that made them really stinky! Like a sour/off fruit kind of stink

Yet Jody's nappies and clothes smell delish!
