I do NOT drink coffee—or tea —for alcohol.
I drink regular Coca Cola-—probably about 2 liters a day.
When I was a kid-—we kept a small container (with lid) in refrigerator of COCA COLA SYRUP, with a small brush like a flux brush for welding.
When a lug nut on a piece of farm equipment had to be removed, the strip was brushed on & left overnight. The lug nut came loose easily the next day. We kids were FORBIDDEN to touch that container.
Watched the farm manager us it on rear wheel lugs on the Minneapolis Moline tractor. HE literally got the lugs off by hand the next day. Only time I remember a tractor tire needing repairs.
I have a neighbor—elderly now—who’s a retired mechanic.
One day he called me as I was driving home from work and asked me to pick up a few cans of Coca-Cola and drop them off.
He was working on an old international cub cadet that’s he’d dragged out of a field— it had been there many years. He had the head off and the cylinders were obviously completely rusted.
I watched as he poured the coke in there, and a couple of days later he called to say they’d all freed up.
First I’d heard of it.
Drinking that much coke- you are probably not troubled by kidney stones.
