Wondering if anyone has tried this and can comment on results. Adi,
recommends Lightning Rust Remover on his site, but his source is $40 a gal.
+S&H IIRC. Side of the carton says 1:20 with water. I can bet these products
are similar to eachother that it wouldn't make much of a difference.

IIRC, muriatic acid is a "watered down" version of hydrochloric acid,
while LRR is probably a form of phosphoric acid.

Very much so, It is ( well, what I have) only 31.45% HCl and inert
ingredients is 68.55% which is as good as water, assuming thats what it
is, could be some other thing.

If you have never used muriatic acid, I have one piece of advice. BE
CAREFULL. The fumes are very dangerous and corrosive. Use outside.
Wear rubber gloves, mask, goggles etc. It is strong stuff and meant to
be diluted heavily. Splash some on your driveway and watch the fumes
to see what I mean.

I wouldn't use it on legs...

A few years back my cousin was heading home from the pool supply store
and a gallon of muriatic acid split open and chugged out in the back of
his Porsche. He was almost blinded by the time he pulled over and got
out. The car interior was completely ruined by the fumes. He went out
the next day and got an Accura NSX. Must be nice to have money.

I have tried muriatic acid on legs. It will remove your rust but also
all of your chrome. It's ok if you plan on painting or rechroming your
set of legs or if you have legs with badly rusted levelers. The threads
clean up very nice and the levelers remove easier once you follow then
with penetrating oil. The downside with muriatic acid is it is
extremely corrosive. A nice clean leg left exposed can rust back over
within a few hours so the metal needs a good prep solution from an
automotive paint supplier and then primed or clearcoated. I advise
wearing old clothes with a jacket to cover your arms and rubber gloves
when using muriatic acid. A face mask and goggles are highly
recommended also. The fumes are extremely toxic and can burn your skin.
I only recommend this for badly rusted legs that sat on a garage floor
for many years. --Bruce

> the pool supply store and a gallon of muriatic acid

Back when I had a pool, I used Muriatic Acid occasionally to bring down
the PH. I bought a gallon, and used maybe 1/5 of it in five years.
Just a "splash" (1/4 cup if that) would bring a 50,000 gallon pool down
two or three notches on the pH scale. By comparison, it would take a
pound of "pH Down" powder the pool store sells to do the same thing.
The damn stuff would even smoke when pouring it into the pool. Yikes!


It's VERY strong stuff. I agree...treat it with respect.

You are a lot better off using naval jelly and a couple of 3M pads to
get rust off of legs. It's not nearly as toxic, you can rinse with
water without fumes, and if you leave the naval jelly on for awhile
first, the amount of elbow grease needed is pretty minor. I use
muriatic acid, in 10% solution, to clean brass castings (the easy way
to restore antique cash registers) and I use it full strength to get
hard water deposits off of my bathroom sink. (the water in my town is
VERY hard- if you drink from the tap, stalactites will grow out of your
forehead!) But other than that and pools, I avoid that nasty stuff -
those fumes will eat holes in your lungs. Literally.

A friend of mine use to use it for cleaning the hull of his fiberglass
boat toward the end of the boating season. He wore rubbers gloves and
had a sponge full of it, but didn't realize it was running down his arm
and pooling around the back of his shoulder while lying on his back
doing the bottom of the hull. Ate a bit of his flesh in the process
and he has the scars to remind him to be more careful next time.
So, watch out.
