SCALE
GONE 35
(35% Food Grade Acid)
Environmentally
Safe, Cost Effective
Industrial Chemical For Metal Cleaning.
Composition
and Effectiveness
Scale Gone Rust
and Scale Remover is a combination of biodegradable,
non-toxic food grade organic acids, detergents,
penetrants, stabilizers, catalysts and other safe
ingredients. It is totally safe environmentally
and essentially non-toxic to man.
Scale Gone Rust and Scale Remover is a very effective
and completely safe alternative to the highly
toxic and corrosive mineral acids commonly used
for derusting, and removal of mill scale and water
scale from steel, steel alloys, iron, stainless
steel, chrome, nickel plate, plastics, glass,
glazed tiled and painted surfaces. Used cautiously,
Scale Gone Rust and Scale Remover is also safer
and very rapidly cleans soft metals such as copper,
brass, aluminum, magnesium, zinc and their alloys.
It is as effective in rust and scale removal as
mineral acids but slower in action unless used
hot.
Scale Gone Rust and Scale Remover can safely be
heated at any temperature up to the boiling point
where its activity equals or exceeds the dangerous
mineral acids. Scale Gone Rust and Scale Remover
saves you money and insurance costs in handling
hazardous mineral acids and disposing of the toxic
waste residues from their use. It also eliminates
the disposal of the alkaline neutralization bath
used in most mineral acid derusting operations.
After derusting with Scale Gone Rust and Scale
Remover you only have to rinse the steel clean
with water ad dry to prevent the cleaned surface
form flash rusting.
The tendency for a Scale Gone Rust and Scale Remover
cleaned surface to again rust is much less than
mineral acid cleaned surfaces, but the use of
a rust inhibitor treatment is recommended for
prolonged storage of cleaned items.
Environmental
Impact and Disposal
The ingredients
in Scale Gone Rust and Scale Remover are naturally
occurring, environmentally safe organic substances
obtained from biological processes. They are widely
distributed in nature, involved in cellular metabolism
and naturally occur in our waterways. The components
are completely and rapidly biodegraded in activated
sludge sewage treatment plants to environmentally
safe carbon dioxide and water.
The oxygen demand for complete biological oxidation
is 0.20 milligrams of oxygen per milligram of
Scale Gone Rust and Scale Remover. Spent solutions
of Scale Gone Rust and Scale Remover that contain
only solubilized iron (rust) and calcium (scale)
ions are non-toxic and completely biodegradable.
They can be safely sewered in most areas and effectively
disposed of by public or private sewage treatment
facilities.
If the acidity is still high in the spent solution
neutralization with a small amount of soda ash
or lime is recommended before disposal. Since
Scale Gone Rust and Scale Remover is completely
and rapidly biodegradable it will not build up
in the environment. Essentially non-toxic, it
does not constitute a significant toxicological
hazard to man or his environment, as do many other
derusting chemicals now in use.
Safety
In Use
Scale Gone Rust and Scale Remover contains no
toxic substances, no volatile acids, and no hazardous
mineral acids and does not give off toxic fumes.
It has no flash point and is completely non-flammable.
Unlike inorganic acid Rust Prevention it is non-corrosive
to the skin and respiratory system. Therefore
protective clothing, rubber shoes and gas masks
are not required for the safety of personnel using
this product.
We do advise strongly against ingesting Scale
Gone Rust and Scale Remover because its mild acidity
will cause severe gastrointestinal upset and requires
medical attention where large quantities are ingested.
We recommend you wear safety glasses or goggles
to avoid eye contact and prevent eye irritation.
If contact occurs wash out eyes immediately with
water. The irritation will stop and unlike mineral
acids no permanent eye damage will occur. If you
have open wounds or other sensitive skin areas,
wear rubber or plastic gloves to avoid skin irritation
and make working with this product as pleasant
as it is safe. Scale Gone Rust and Scale Remover
does not cause toxic or corrosion hazards to operating
personnel or damage the environment.

General
Product Uses
Scale Gone Rust and Scale Remover was scientifically
developed over a period of years as an effective
and safe method of removing rust and all types
of scale from mild steel, carbon steel, steel
alloys, and low chromium stainless steel and cast
iron parts.
Scale Gone Rust and Scale Remover is also very
effective and safe for removing rust, tarnish,
oxides, dirt, cement, plaster of Paris, water
marks, food residues and heat scale and weld marks
from 300 to 400 series stainless steel, monel,
copper, brass, aluminum and its many alloys, all
plastics, glass, painted surfaces, porcelain,
glazed tile, chrome plate, nickel plate and fabrics
with acid stable dyes.
When removing copper or rust stains from colored
fabrics check the deruster on an unexposed part
of the fabric to be sure the dye is stable before
removing the stain.
Specific
Applications
Scale Gone Rust and Scale Remover has been found
to be safe and extremely effective for removing
fouling and scale from fire-tube and water-tube
industrial steam boilers, marine boilers, utility
boilers, cast iron boilers, shell and tube heat
exchangers, water lines, water side of oil coolers,
evaporators, cooling towers, aluminum and copper
air conditioning and refrigeration heat exchangers
and water jackets on electric motors.
Scale Gone Rust and Scale Remover also is very
effective and safe for the industrial cleaning
of copper, brass, aluminum, nickel, steel and
shot cleaned stainless steel, zinc and alloy castings,
galvanized steel, concrete molds, gas wells, cleaning
and etching cement floors for paint adherence,
pre-electroplate cleaning and cleaning steel for
better paint adhesion.
Automotive applications are copper and aluminum
radiator cleaning, antique car restoration cleaning,
parts derusting and cleaning, aluminum truck brightening,
cement truck cleaning, transmission housing cleaning,
pre-paint rust removal, bumper cleaning and safe
brightening of mag wheels.
Scale Gone Rust and Scale Remover is sold as a
concentrate that is cut with water for use. At
temperatures below 150 F rust removal is slow
and the cleaning of soft metals is fast. However
from temperatures of 165 F up to the boiling point
the rust removal rate on heavily rusted steel
surfaces is much faster and corrosion rates on
the steel are very low. High temperatures also
enhanced rust removal rates on light and medium
rust levels. Brushing heavily rusted surfaces
and agitating by boiling, circulating or stirring
also helped rust removal. Before removing rust
from steel surfaces, always check the system for
copper, brass or other soft metal alloys and isolate
them from contact with the cleaning solution if
cleaning is to be done hot.
