"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)
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.
