I purchased 2 one gallon bottles of Drain Gel last year. I had half a bottle left over that I am using before I purchase a new bottle. It is not as thick as it was last year. Is it better to use fresh Drain Gel? Does it expire?
Drain Gel has a shelf life of several years when stored at room temperature out of direct heat or freezing temperatures.
