do your products expire?
the simple answer is that all of our products have a shelf life of about 2.5 years. after that, you may begin to see changes in the way they look, smell or work. that said, your product could be older than that and still work perfectly well. light, heat and other factors can age products faster, so if it hasn’t been exposed to them it may be just fine.
the best thing to do is give it a try. if it seems to have lost its power to fight dirty, just empty the bottle and throw it in your recycling bin. if it still cleans up a storm, then keep using it to clean happy.
