I dont do a lot 'cos i have a dishwasher, but it has struck me recently that the method i use isn't very hygenic. I use one of those sponge scourer things, then rinse it under the hot tap, squeeze and let it dry for use the next day. Bacteria city. I probably use it for a week then change.
What do you do? I also feel a bit bad about chucking them as it is such a waste and bad for the environment.
Well done if you haven't fallen asleep after reading this dull dull post
