I bought Oxine in Canada, and mixed the soluttion with water, inactivated oxine. I just wondered how long is it good for? If you mix it and put it in a sprayer bottle as a disinfectant to be used later, does it expire after like 10 days? or it is good as long I use it. I mixed it a week ago and I am due cleaning my house today (where i had pigeons and droppings) I wonder if the mixed solution is still good. or I need to make a fresh batch. Please let me know..
