Does anyone know what's the "Shelf Life" for Kreen?
I'd like to order 4, one quart containers, to keep on hand for people that may need an engine cleaning.
However, I'd like to know how long the shelf life would be if they still remained sealed shut and stored indoors?
Thanks in advance.
I think I read somewhere the shelf live for Kreen is 2 years? In fact I'm pretty sure it is 2 years. HTH
