i have used it before but the silver irons is a problem as the wine industry does not use it and u can not export it to foriegn countries with silver in it .
try dophor at esb .
he a post form on the grumpys forum about one shot from one of the employeies of grumpies.
Guys,
'One Shot' is a Low Foam, high acid detergent based sanitiser. It contains no iodine and can be used in hot or cold water.
Its U.N. Number is UN 1760.
It is corrosive and contains Ortho-Phosphoric Acid.
It is primarily a dairy industry product and is used in vat and line wash systems.
It's active constituents are Phosphoric Acid and ALKYLARYL SULPHONIC ACID.
It is yeast friendly and in our opinion is better than Brewshield or Sodium or pottassium Metabisulphite.
The Brewshield product as we understand it contains colloidal silver, not thatthis is an issue, it's just that if you were a wine exporter, you wouldn't be able to export your wine anywhere, it's use is illegal for use in the wine industry in most countries.
The latter two, just kill yeast. We are making a yeast based product. It is the yeast that makes the beer, provides significant impact on it's flavour, it protects the beer from bacterial invasion and preserves the beer in bottle. Our response, don't use stuff that impedes yeast!
Until something comes along that is as safe to use and as effective as One Shot, we will continue to offer it for sale.
Oh! One other thing, this is the product we use in the brewery, so this is the product we sell!
Simple Logic Really!!

Dave
