citric acid is used for canning and usually can be found in late summer at Safeway with all the canning jars.
it is also used in bath bombs

and, as I discovered tonight, it takes off some wicked at-least-40-year-old limescale crud down the toilet pipe which I had thought was black unglazed porcelain!
(moved into an unrenovated apartment in Europe, have been discovering all sorts of rather unsavory things. Thank God for high ceilings and other cool weirdness
to make it tolerable)
