This is an all purpose cleaner/steriliser for ensuring all your homebrewing and winemaking equipment is clean and sterile. to use, simply dissolve 3-4 teaspoons of the powder in around 10 litres of warm water and use to clean all your brewing and winemaking equipment.
Its main ingredient is Sodium Silicate and in use it feels a little like the sugar soap solution you would use to clean the walls when decorating. Some people may find that this is an irritant, so care should be taken not to exceed the stated doses and to wear protective gloves if needed.
It may also give off vapours that can be an irritant to the nose, lungs and respitory system, so extreme care should be taken not to lean over the brewing bin and inhale deeply !!! (It is, after all, designed to kill nasties that would otherwise ruin your brew)
