I went to my local Dairy and asked them for 'milkstone remover'
which is nitric and phosphoric acid @ about 24-28%.
They buy it buy the barrel... I brought a jug.
I dilute that 1:1 with H2O and presto change-o it works just like the Ospho which is approx 14% Plus... I have XX strength Ospho on hand when I need it for no extra $$$$!



Give me ambiguity
or give me something else
