What is shelf life unopened bags? Thx!
Just trying to figure out how much to order. Some pesticides/etc have a 2-3 year shelf life unopened. I just don’t want to lose any effectiveness if I buy more than I need now and it won’t be good for bath remodel down the road.

Timbor is basically Boron which is a mineral element. It does not expire - ever. As long as the product remains dry, it should last many, many years - decades.
