Star San quick question.

[mickhew]

Hello. Sorry if this has been asked many times before (probably has!). I have 2 litres of Tesco Ashbeck spring water, and have just added 4 mls Star San, I intend on using this in a spray tomorrow, to sanitise my bottles.
Is 1ml per 500ml o.k? I have done a quick forum search, but am getting different opinions. Cheers.

If you purchase either 1ml, 2ml or 5ml syringes (plenty on ebay) then you can measure out to tenths of a millilitre (if you feel so inclined)
