Storing Star San

[SE10PAT]

i've just started using Star San to clean my equipment, mixing 1.5ml to 1 litre of water.

Does anyone know how long I can store this for in some old 5 litre still water bottles?

cheers
Pat

Apparantly it's fine until it goes quite cloudy.

I still use mine even after it's gone cloudy though. I have never actually thrown any away, it just seems disappear over time.

I reuse as well, so I pour 5 litres of mixed Starsan into a corny, shake it around a bit, then gas up the corny and run the Starsan out through the tap back into the 5 litre bottle.

I have the bottles anyway as I have hard water that is no use for Starsan so have to buy Tesco cheap water to mix it up with.

OK thanks Steve. Mine does actually appear to be a bit cloudy anway when I mixed it up, it had been shaken around in the fermenting bin for a bit so do you think this would cause it?

I am only worried as I have been making a few brews lately and obviously I want to ensure that i'm sanitising everything properly with the new cleaner.

Found this on a US stores listing for Star San

" Reusable: a solution of Star San will remain effective for up to three to four weeks in a sealed container; it is effective as long as the pH is 3 or lower"

pH tester pens , anyone ?

they work well enough as long as you calibrate with a buffer solution , preferably two point . Sounds complicated ? It isnt at all , calibrating consists of dipping it in a fluid of a known pH value and turning a little screw until the pens LCD reads the known value of the fluid , the buffer solution . Look after them and they last a few years , and then cheap enough to buy another . The first one I had over 10 years ago was £60 , now they are everywhere for a tenner - some even in the UK ! :thumb:
