J-cub's bathtime antics have got so vigorous (he likes to like on his back and slam both legs at once into the water, sending waves all over the place) that I now have to have the shower curtain pulled almost completely across, tucked into the bath, to prevent him flooding the whole place every day. In so doing, I realised that having something covered in mildew trailing into his bathwater probably wasn't terribly healthy.
I googled useful hints for removing mildew from shower curtains, and the general consensus seemed to be soaking the whole thing in a bath of bleach. I don't like bleach. It's far too deadly, and it's made and tested in nasty ways, and in the same way that I don't want something mildewy trailing in his bath, I don't want something bleachy trailing in his bath.
So I took the whole thing down, scrubbed it by hand using good old washing up liquid, and put it in the washing machine with some vinegar, bicarb and lemon juice. Result: good as new.
I don't have any recent pictures of J-cub having bathtime fun, so here's one of him months and months ago, sporting a little beard:
