    Is it? I did A-level Chemistry and I couldn't then, and still can't now, read a litmus paper. Looks between 1 & 3 to me. Hopeless.

    Am I the only person who uses a 1ml syringe to accurately measure only what I need for the job? Today made up 200ml solution with 0.3ml to sanitise a fermenter. Other small jobs from the spray bottle.

    Maybe mine will be the longest lasting bottle ever.

    Somewhere between 1 and 3?

    I'd take a guess at two then :mrgreen:

    Why doesn't someone invent litmus paper for the colour blind? :grin:

    I think they did. It's called a pH meter.

    I would say 1 or 2. I have never had a problem with starsan changing PH over time and mine is really cloudy. Only problem i have is inevitably i need to change it as seems to pick up dust, dirt and other debris over time. I used to use RO water for mine but not done recently, must try it again see if it makes any difference

    Deionised water used for topping up car battery's is not necessarily sterile, distilled water is.

    Another post that might be anathema to those on here; I've never properly measured how much StarSan or how much water I mix it with. As long as it goes frothy, I guess I've used enough.

    No infections thus far (probably jinxed myself).

    Funny that this has just popped up. I’ve been dozing with 1 oz per 5 litres not 5 gallons. Oops. Actually read the instructions (properly) last night while waiting for my priming water to boil. I’ve been over dosing for a year now. In the plus side I’ve always had plenty of bubbles/foam

    I keep mine for a while, and just use common sense about how much to use it. Always airing in the side of caution.

    Today I have mixed first time with RO water (use it for my aquarium), mixed 2ml per 1L. First thing I noticed, my tap water would go cloudy/milky, with RO it is very clear and much more foamy. From now on RO water with star san for me.

    Didn't have any infection so far, but still will change

    +1 for this. I use on of those syringes you get free with Calpol for the kids. Two 5ml squirts in 5 litres of cold water. Lasts from Brew day to Bottling day. Sometimes beyond if I've got two brews in quick succession. Slightly off topic, but is there still a Starsan drought in the UK? Remember reading something about that a while ago?

    I make 5L at a time in a re purposed deionised water container. It’s easy just to use the built in measurement cup.

    Good luck finding it in the UK though at the moment.

    Ha, just randomly dropped by and caught this reply to a comment of mine from years gone by. Well I can report back, my bottle of starsan is indeed still going strong. It came with 16oz, and there is 12oz still remaining. Still brewing regularly; 2 brews in the last 3 weeks. Still use a syringe into 200 or 300 ml of brita filtered water for immediate throw away, fermenters, kegs, etc. And distilled water in a spray bottle for longer term use, spoons, jars, scissors, thermometers and the like. At about 1 oz per year, I've still got 12 years left in this bottle of starsan.
