Hi! I'm having cloth nappy issues and I need a better way to strip. I've done the plain hot water washes until there's no suds but they're still leaking and they have a stiff texture! I think instead it's the super hard water of London. I use a magnoball and little powdered detergent generally, but even the cheeky wipes come out scratchy (we've speed using them). What would be a good strip method for hard water and what's better for maintaining it? Thanks for any advice...!!
