I bought a large clear bottle of Bait Fuel a couple of years ago that was clear in color when purchased. The bottle was kept in a cool , dry place with the cap screwed on tight , now two years later Bait Fuel has turned to an amber color ? Not sure what’s going on here with Bait Fuel - has the effectiveness changed with the Bait Fuel color change ?

I can't imagine it would lose effectiveness. Now if your line or urine darkens...we have a problem.
