My cloth nappies have started to have an ammonia smell on them after washing, and from reading on here it seems there might be a detergent build-up and I need to strip them? The only problem is that I'm on a water meter and this sounds like it will use loads of water. Is there anything else I can try first to see if it will get the smell out? I haven't been pre-washing them, just doing an extra rinse, so maybe I should start doing that (although TBH if I'd known this much water was going to be involved I'm not sure I'd have gone down the cloth nappy route - I don't think I'm going to end up saving money as what I don't spend on disposables I'll be spending on my water bill!) If I do strip them now, any tips for avoiding the ammonia smell in future? Or do you always need to strip them periodically?
