Milton Fluid

[jansman]

This is a good , solid household name. It is also a damn sight cheaper than "camping" steri - tabs. My Wife always has it in for sterilising my cycling bottles etc. Never occurred it could be used to clean up water.

This is a great find! I need to clean inside of my water butts, and eventually inside of some demi-johns. Milton is on the list now, to use and to store. Thanks all.

Just searched online in the supermarkets:
Sainsbury 500g £1.99
Tesco 1l £2.39
Asda 1l £2.

Hurray! I'm going to the South East meet on Sunday at Three Bridges, there's an Asda at Crawley, will buy a couple of bottles there.

Asda own brand baby bottle steriliser is even cheaper at 64p. Tesco is about the same and the label on the side last time I bought it confirmed it was 5% sodium hypochlorite. I keep a bottle in the medicine cabinet for sterilising eye baths etc so good to have in the house even if you don't need it for water

Thanks Maryb! I buy own brand all the time, and it never even occurred to me on this, aargh.

The cheapest method of adding chlorine to water is to use plain, unscented household bleach (5% sodium hypochlorite). Add one drop (0.05ml) per litre – two if the water is cloudy and leave for at least 30 minutes

But where can you buy this? I keep looking at the bleach - admittedly in a supermarket - but they all have perfumes etc in it.

try the £1 or 99p stores check the label for 5% sodium hypochlorite). but dont forget bleach smells anyway

see above - baby bottle steriliser is unscented sodium hypochlorite. Some labels are more informative than others but at least one brand I have bought states that it is 5%

Lidl used to do it in 5L bottles for about a pound.
