I use Cheekywipes reusable cotton pads when I get my period. Unfortunately 4 weeks ago I unexpectedly taken into hospital and was not able to return home until this week. The pads were soaking in a mucky box for all that time (I didn't have anyone to go home and sort them out for me) As a result they've developed black mould on them 
(gross not envy). I've tried scrubbing them with Vanish, put them through the washing machine twice and now I've left them to soak in cold water with yet more stain remover. Is there anything else I can do to save them if that doesn't work or is it just a case of binning them and starting again?
