QUESTIONS & ANSWERS
Q)How does it work?
E-Z SAFE SOLUTIONS ® EVAPO--RUST
works through selective chelation at a pH of 6.1 to 7.0 (neutral).
Selective chelation is a process in
which a large synthetic molecule forms a bond with metals and
holds them in solution.
Most chelating agents bind many different metals. The active
ingredient in EVAPO-RUST
bonds to iron exclusively. It can remove iron from iron oxide,but
is too
weak to remove iron from steel because the iron is held much
more strongly.
Evapo-Rust is only a rust remover.

Q)Do parts have to be completely clean before immersion?
No. EVAPO-RUST
has detergents which penetrate oils and dirt. However, surface
contaminants do slow the process.
The soils must be penetrated before EVAPO-RUST can come
in contact with the rust underneath.
Soil residue will also shorten the life of EVAPO-RUST.
Heavy greases and cosmoline should be removed prior to de-rusting.
Also, adding hazardous
contaminants can change the disposal requirements.
Q)Will EVAPO-RUST remove bluing and other
oxide finishes?
Yes. EVAPO-RUST
will remove these in about 30 minutes. Anodizing will not be
removed.
Powder coating and paint will not be removed as long as the paints
do not contain oxides.
Q)What if I have a multi-metal or multi-surface item?
EVAPO-RUST will not harm copper, brass, aluminum, plastic,
rubber or vinyl.
Even more amazing, EVAPO-RUST will not remove non-oxide
coatings, such as paint,
or chrome, that are still bonded to the surface. Do not use with
Cadmium coated surfaces.
Q)I get a black film on some parts after using EVAPO-RUST
.
What is it and how do I remove it?
The black is carbon from the steel. Generally high carbon
steel is used in making items
that are flexible (e.g.springs, saw blades, etc.). High carbon
steel and tool alloy steel items, when de-rusted,
will have a darker appearance. Much of the carbon can be re-moved
simply by wiping with a cloth.
Q)Can I spray EVAPO-RUST on the rusted area?
No. EVAPO-RUST only works in the liquid form. When sprayed
on a surface, the water in the solution
will evaporate before de-rusting can be completed. It can however
be sprayed on as a rust preventative.
Q)How can I use it on a verticle surface or one too large
to soak?

Q)How long does EVAPO-RUST last? Does it evaporate?
EVAPO-RUST has an indefinate shelf life* and can be
used over and over until it
absolutely stops working. Only water is lost to evaporation.
EVAPO-RUST
has a tremendous work load. One gallon can remove 1/2 pound of
pure dry rust.
Rust is about 1/17 the weight of iron by volume, which means
its workload is substantial.
On average, one gallon de-rusts up to 300 pounds of light to
moderately rusted steel.
As the iron is removed from the iron oxide, carbon from the rust
is released.
Some parts may have a black film after using EVAPO-RUST.
High carbon steel and
tool alloy steel items, when de-rusted, will have a darker appearance.
The carbon can be
removed simply by wiping with a cloth when rinsing with water.
The more you de-rust,
the blacker the solution becomes. EVAPO-RUST is spent when
it is pitch black and no
longer performs.
Only water is lost from evaporation, if any of the bath evaporates,
simply add fresh water.
*Shelf life is for un-opened product. Once opened, The life of
the bath will vary due to
biodegradability (bacteria introduced into the solution). After
using Evapo-Rust,
it is better to cover the solution, but still allow air to the
bath. Pouring the solution
back into a sealed container will allow the anaroebic bacteria
to begin the degredation process.
Used, open baths have continued to operate for over a 12 month
period.
Q)How do I know when the bath is spent?
The bath will turn completely black and will not perform.
Q)How do I dispose of the spent solution?
If no hazardous contaminants are introduced, only the iron
content of the solution should dictate the disposal
method. In most cases, it is sewerable. Always dispose of product
per local, state, prov., and federal regulations.
