Product Questions

What kind of shelf life does Selcon have once the bottle has been opened / how can I tell if it is too old?
Question by: Bruce Hanson on Aug 8, 2015, 10:35 AM
Great question!
The Selcon will have a refrigerated life of approximately 12 Months maximum. There is not a great way to tell, and the negative effect of using old selcon won't be bad, some of the effectiveness of certain parts will have worn down.
