Coolidors

I eventually managed to get a litre bottle from from a model-train company. I had tried chemists, hardware/motoring shops, petrol stations, supermarkets (grocery stores as well) with no luck. The bottle I bought ended up being about £9 with postage - would've lasted for ages if I hadn't cleaned my fridge with it, but there's still a fair bit left so it's not the end of the world. I'm not certain, but it seems that distilled water is harder to get hold of in the UK, than in the States...
