Muriatic acid

    Alum works fine for removing bits of broken drill bits,
but I find that Hardware store variety Muriatic acid works even
faster!  

G’day; “Muriatic acid” belongs in the pre-nineteenth century
times. Let’s get into the 20-21century and call it by it’s
proper name: Hydrochloric acid (HCl)

Cheers,

Dear John, Well at least I didn’t buy it from the “Iron Mongers”.
I included the "19th century name because asking for HCL at the
hardware store (in the US) will get you funny looks and some
reply like “Uh, We don’t stock anything like that.” Using the
19th century name will get you what you want from that source.
But thanks for reminding us that “muriatic” is truly an archaic
term. Eben

True enough. Now all we have to do, it seems, is convince the
hardware stores of this, since dilute HCl is still packaged and
sold as muriatic acid… :slight_smile:

using proper name is a good idea, but for those of us getting
this at a hardware store, they would have no idea what you are
talking about, at least around here ( eastern US)

Unfortunately, John, the term “muriatic” is still used here in
the U.S. Muriatic Acid can be bought in most hardware stores
for the cleaning of masonry. If you ask for hydrochloric acid
in most hardware stores or masonry suppliers, they don’t know
(or won’t admit they know) what you are asking for.
Hydrochloric acid can be bought only from chemical suppliers, at
much greater expense, and only by convincing the supplier that
you are a legitimate purchaser, who won’t be using the stuff for
manufacturing explosives to be used in terrorist attacks.
What’s the difference in Muriatic and Hydrochloric? Just a
little water to dilute hydrochloric into muriatic, a little
purity of product, and PRICE!!! Buying nitric and sulphuric
acids is even worse! Even filling your truck with deisel fuel
when there is a bag of fertilizer in the back can raise a few
eyebrows in some places. A sad statement on the state of U.S
and world affairs.
