Does stain go bad sitting on a shelf?
So I bought a bunch of different Cabot stains on clearance at a local store for like $2-3 per quart-sized can! I get home to try one (colonial maple) and while stirring it, there's like an inch or more of stuff that settled out to the bottom that I can't seem to get back into solution. I've stirred it vigorously for about 2 minutes and when I pull my stir stick out, I can see chunks in the liquid.
Can this be saved, or should I return it?
Edit: Everything I bought were new, unopened cans.
