First, one of the elements of kosher is cleaning and severe cleaning to
purify dishes, pots and utensils.
Secondly, in the military, 'bug juice' powder, think Kool Aid straight
from the packet, was soveriegn for cleaning cooking
surfaces.

Yes. Actually I use the special photo stuff with ph-indicator. But simple citric acid from
the drug store does as well. It is much cheaper then the photo stuff. Unfortunately I got
this knowledge after I had purchased the photo stuff already.
Coca Cola should work too as it contains phosphoric acid. (For cleaning. I am surely not
going to dip my fibre based photo paper in Coke. ;-) )
Obviously all this stuff works great to remove chalky deposit caused by
water evaporation. E.g. on the water cooling of your mainframe - or
your coffee machine or tee kettle.

Incidentally, I found some acetic acid (fairly
concentrated too), in
the 'Kosher' section of the local supermarket. I have no idea what
the intended application of it is, but it's quite useful for cleaning
up NiCd corrosion too.
Well. Actually acetic acid is the acid in vinegar. Most
likely this
stuff is just pure acetic acid without any "flavor".
Remember: If you are going to dilute concentrated acid _allways_ pour the acid into
water. Never do it the other way around. Pouring water into concentrated acid may cause
the water to heat up quite quick. High enough to make the water boil instantly. The result
are drops of water and concentrated acid jumping around. Preferably onto your skin and
into your eyes...
(I use
citric acid in the dark room because it doesn't smell.)
As a stop bath?
