We got a ton of pre-used diaper covers on Ebay for a serious steal. They're all in pretty good condition and are Proraps or other brands in the same style. Some have some brown staining on the inner gusset fabric, though. Would washing and hanging to dry do a decent job this time of year? It is supposed to be warm tomorrow at around 75 or so.
I'm not too concerned because it really is mostly on the gussets, but is there anything else I can try?
