I've had a MULE for around 4 years now, and the last year or so, the lid on the reservoir has been almost impossible to remove when I need to fill it. I have been wondering if it is the o-ring around the lid that is maybe dried out, and needs to be lubed or something.
Anyone else had a similar issue, and what did you use to solve it, besides buying a new reservoir? Is there something specific that should be used for lube that is around a food grade container? I tried using some Crisco one time, but that didn't seem to help...
