Good idea for all canned chemical products
But dont expect products to last more than a year or so They can but not a good idea keeping them on the shelf as they do go bad in short order opened or not.
I have Bought brand new products that were bad as supplier did not rotate stock or had it on the shelf way too long.
When you buy products its hard to know how old it is it could have already been on a shelf for over a year easily. Good products have a tracking code on them but breaking the Batch code requires contacting the MFG in most cases.
