A while back on the
old forum there was a thread on getting the rust out of your
gas tank. There was a discussion about the acid that
comes in the 2 part creem kit and that it was available under
another product (hardware store?) name. Does anybody
remember what that was.
I dont have enough rust
to do a coating of the whole tank, but I would like to clean
it out a bit.... suggestions appretiated!
Steve!

Steve, thats the
stuff. Cheap, strong and very toxic to painted surfaces as
well as lungs.
Procede with extreme caution!!!!

It isn't muratic, it
is Phosfuric. I think I spelled that right. Muratic
dosen't compare to this stuff.
you can
buy it by the gallon and it is cheap. It only eats rust.
I have an address of the place to order it
from. I PROMISE YOU I HAVE CHECKED INTO THIS AND IT
ISN'T MURATIC ACID.
the company that i get it from
calls it Metal Etch.

Yeah, I know about
muriatic acid. One missed drop and kiss your paint
goodbye... I'm pretty sure you're right Tomcat. I
think it was phosfuric (or however it's spelled) acid. I
was under the impression that it was available under a brand
name (or as a main ingrediant in something) in hardware
stores. I'll take a look around here for it.
Thanks!
Steve!

OK, guess I have to
clear this one up once again, it seems everytime this comes
up, everyone grabs at straws and we get a bunch of confusing
answers.
The acid in the Kreem kit is
Phosphoric acid, 1 molar solution(full strength).
This
type of acid does not attack and errode the metal, but instead
converts the rust back into metal, and then leaves the surface
coated with a phosphate ion so it will not corrode again.
Muriatic(pool) acid, is sulfuric acid, and like
hydrochloric acid, it eats away the metal, etching it.
Neither acid converts the rust, nor do they leave the
metal surface neutralized, so it will quickly rust again if
given the chance. Theses acids can, and will creep into the
seam areas of tanks with advanced corrosion, and potentially
become entrapped in the cracks in the seams and cause futher
metal errosion. Although readily availlable at hardware and
pool supply stores, they are not the correct type of acid for
rust removal, and can cause nasty burns if not handled
carefully.
Their use as rust removers for gas tanks is
not reccomended, or ideal, as they have the above mentioned
drawbacks, even though others who are ignorant of these
facts may argue differently.
Phosphoric acid can be found at hardware, and Marine hardware
stores, it is sometimes labeled "Ospho".
Tip, use hot water, and never add
water to acid, as it may spatter. Instead, always add acid to
water.
Another tip: Use denatured alcohol to
remove the residual water left in the tank from rinsing out
the acid. I save the acid in a 5 gallon plastic gas can for
re-use, it can do several tanks.
Hope this
clears things up, and the instructions with the Kreem kit
lists the type of acid, check it out. |
