So I know about refilling, topping off, and throwing away once it tastes burnt or performance drops.
BUT, what if you keep it moist always, you can't see any visible burning nor taste any? Is it safe to continue to use that particular carto? Or is there a ballpark expiration date as to when it becomes unsafe/unhealthy to continue to use that carto?
Thanks in advance!
