I've bought 2 jars from Amazon, both Bormioli Rocco Fido glass storage
jars with wire latch and rubber(?) seal. I don't wanna offer an
outright condemnation of the product, but I will say they both reek of
coffee grounds, the seal seemingly causing most of the aroma retaining
problem.

Anyone know of a sure-fire remedy for relieving rubber seals of the last food
stink?
