As one does every 20 years or so, I can across a HUGE bag of something
called 'Phosphoric Acid' which I obviously bought for some use, but
what was it used for?
When I first saw the bag the words 'growmore' came to mind, but bearing
in mind the reliability of my memory it could be anything!
So, what sould I be using it for?
IIRC phosphoric acid can be used to etch glass - although a customised
grenhouse seems a little OTT :-)
However this would be a liquid, not a solid.
YDRC.
A very strong solution will certainly etch glass.
And can be used as a rust-remover
