I know from my own experience, that 'Kraft' brand
'Macaroni-and-cheese' ( the traditional version) will do so
under certain conditions.
Or, some discrete aenerobic Bacteria as may in some way
occupym, or opportune in - in my case - 'left-over' (and
prolongedly room temperature so, at that, of) Macaroni. I
later surmised, some Bacteria's exertions or incidentals,
had 'eaten' or otherwise chemistrated holes in the Stainless
Steel pan.
Having made some of this Macaroni, and having not finished
it, I had set it aside, where it got set further aside,
where it became forgotton. Later, (some weeks) realizeing my
neglect, as, "Where the hell IS that Saucepan, anyway"????
and finding it under the table against the wall...I added
some water to soften things up for an impending vigorous
wash of the Stainless Steel Sauce-pan...a nice old 'Revere
Ware' it so happens...
Then...forgetting it again for some weeks or so, with the
Water having been added, and then once again renewing my
aquaintance with it, and then finally addressing the actual
deed of cleaning it out, I discovered a number of small
holes about the diameter of say a No. 2 Pencil lead. Through
the bottom and lower sides of it.
I imagined some galvanic or acidic buisiness had been
afoot...from some Bacteria or other...and of an anaerobic
way-of-faith at that, as the holes had occured beneath the
level of the Water, and the subsequent festerings and all.
Otherwise...I'd think that anything as may 'eat' a hole in
Stainless steel, should likely be a serious substance to
handle or use...I would be quite careful with such things.

Subject: Etching a Hole in Stainless Steel?
Does anyone know if there are chemicals or something out
there that
would etch a hoel in stainless or make a small area more
brittle or
less durable so that a regular drill could go through it?

Hi Steve,
Depending on the type of stainless you are working with, it can be very
difficult to machine or drill because it can "work harden". I have used
sulphur based pipe thread cutting oil with some success. If drilling using
an electric hand drill, I have to apply extra pressure, and have broken a
few drill bits. Start the hole first with a center punch to prevent the
drill bit from skiding across the surface, and drill using increasing sizes
of drill bits. Use very good quality drill bits that will not dull easily.
Here are some web sites with information on different cutting fluids:

I hope this helps some.

Once again, let me remind people that this discussion is about drilling
holes in the stainless jacket around the kiln. If the jacket is still in
place, DO NOT use a center punch, because that kind of shock can seriously
loosen the refractory.
