I hand wash all our blue jars. And some are pretty gross! I've found all sorts of barn refuse inside our jars. But I scrub and dry, then look closely, scrub some more, dry some more, and try to determine if our buyer will be happy or not when they pull this particular jar out of the box.
I'd say for every jar we send off to a new home, at least four are rejected. It can be very frustrating, especially when I'm trying to work quickly to fill orders. It can be quite disheartening to clean 20 jars (or more!) only to get five usable ones. In the jars pictured above, the pints were good, but the quart had a ding in the heel and had to be rejected.
The tools of the trade? A nice and strong Scotch-Brite Pad, a toothbrush, dishwashing soap, and vinegar. If you have any sticky residue on a jar (like tar or old jar rubber), soak it in pure vinegar awhile (maybe even overnight) and the stuff just falls off.
When all the frenzy hit last week, I started to complain a little. Melissa, our 16-year-old told me firmly, "I don't want to hear it. You brought this on yourself." Teenagers. Gotta love 'em.
