Biobor

[tmmar]

Does anyone know how long Biobor lasts once the container is opened. I usually only use it when the coach will be sitting for more than 4 months which is usually around the end of the year. If I open the 32oz bottle, I will not use it up for a couple of years so the remainder sits around for a while.

I read it to mean keep the cap tightly closed after using.

Do you know if that is if it opened or still sealed from the factory?

I read on a boat forum that Hammonds, the maker of biobor says the product should be stable for three years from the date of manufacture if it's kept tightly sealed.
