DC and I all wear Crocs and every few months I put them all in the dishwasher on top rack with kitchen bin lid on bottom rack for a good clean. They come out like new, as does the bin lid. I mentioned this to a friend the other day and she looked a bit horrified like she was making a mental note not to ever eat off my dishes again. Is this disgusting? I put plates that had raw meat on them in the dishwasher so assume if it can kill that bacteria shoes will be ok too.
Also, have been considering putting all the Clarks school shoes in too but haven't had the courage yet. I tried Clarks in the washing machine on a special sport shoe setting but it didn't get them clean at all. They weren't ruined in any way though.
Lastly, (I can see this coming) please don't say I am BU just for wearing Crocs! I have size 9/ 9.5 feet and not a huge array of options. I stay away from the 'clog' styles though.
