Metalterj #1018
Industrial Liquid Detergent & Rust Preventive

Usually the most cost-efficient detergent for removing common industrial substances from ferrous metals. Prevents in-wash rust, prevents after-wash rust for over 30 days, inside, at ambient temperatures and humidity.

Use on all ferrous metals, glass, most plastics, and other materials not affected by high alkalinity. Do NOT use on aluminum or other soft metals and alloys. Removes cutting oils, petroleum oils, vegetable oils, paper labels. Removes most other lubricants, drawing compounds, buffing compounds, rust inhibitors, waxes, mold-release agents, marking inks, and many other industrial substances. Use at any temperature; as most detergents it removes most substances faster at higher temps. Typical uses:

Performance Properties & Active Components

Dissolves instantly in hot or cold water; its low viscosity assures consistently accurate solutions when fed through a metering pump or suction device such as a venturi injector. At recommended use dilutions it provides:

  • Quick wetting, penetration, dispersion and suspension of solids and oily substances, but with limited emulsification which permits the removal of oil from cleaning solutions by coalescing or skimming.
  • Low foam at all temperatures; very low foam over 100F.
  • Simultaneous cleaning, protection of all metals from corrosion, and assured rust prevention -- even for cast iron -- and for over 30 days if not rinsed in plain water.
  • Quick, virtually spot-free rinsing if desired, and scale-free equipment -- both due to low surface tension and deactivation of calcium and other hard-water ions.

Contains hydroxide, buffered alkalies, organic chelants and sequestrants, organic and inorganic rust preventives, and a synergistic blend of anionic and nonionic wetting agents, penetrants, and dispersants. Contains no phosphates, no nitrites, no chromates.

Recommended Use Dilutions

For use in spray washers to remove dirt resulting from machining
and other manufacturing processes, at least:
1% = 1.28 oz/gal
For use in vibratory, spindle, or tumbling machines:
Rust prevention not needed: at least:1/2% = 0.64 oz/gal
Rust prevention needed for parts or media: at least:1% = 1.28 oz/gal
For any use requiring rust prevention inside, at ambient temperatures
and humidity, on rust-prone materials such as cast iron, or under
adverse storage conditions, or for over 30 days, at least
3% = 3.84 oz/gal
For cleaning and/or rust prevention under any unusually severe conditions, up to:10% = 12.80 oz/gal

Dilute in water to suit the job. For cleaning effectiveness, the dilution required depends on the quantity and type of dirt, porosity of the surface, temperature, soak time allowed, and the degree of agitation applied by the cleaning method used. For rust prevention, the dilution required depends on type of iron or steel, after-wash storage conditions, and required rust-free storage time. Dilutions are shown as % of solution volume and fluid ounces per gallon of solutions.

Rust Prevention

Test results using the test below and a similar test on cast iron were:

  • Stored inside at ambients temps varying from 30F to 90F, and
  • At ambient relative humidity varying from 40% RH to 100% RH,
  • After 2 years: No rust. Test discontinued.

Customers have reported comparable effectiveness under actual use conditions on many types of steel and on cast iron engine blocks. Our test experience indicates that if no rust occurs within the first 48 hours, none will occur in subsequent months. A 3% solution on steel or cast iron dries in less than 3 hours under common conditions. When dry, the metal has no visual change, it feels smooth and waxy; it is non-sticky. Before painting, rinse metal with water, hot or cold, and air-dry at once.

Test method, using steel chips from a machining operation:

  • Drain coolant from chips; leave chips dirty.
  • Prepare 100 ml of 3% solution. Pour about 80 ml of solution into 100-ml beaker. Add chips; use about 10 gm (= about 1 teaspoonful).
  • Stir 2 min to assure wetting.
  • Pour off all but about 1 ml solution.
  • Spread chips, wet, on filter paper. Store in intended storage area.
  • At suitable periods, observe for rust on chips or on filter paper.

Use Temperatures & Time Required

Hot solutions, 140F to boil, provide the most effective cleaning. “Cold” solutions, at ambient temperatures, remove many common industrial substances such as oils, rust inhibitors and buffing compounds; when used cold, higher concentrations and longer time may be needed. For some substances, especially if they are solids or very thick at ambient temperatures, hot solutions are essential.

One to 15 minutes is normally required for parts. The time required for equipment varies greatly; some substances are removed instantly on contact, others need hours.

Alkaline liquid. Contains caustic soda. Avoid contact with skin and eyes. In case of contact, flush with water for at least 15 minutes, for eyes get medical attention. Use rubber boots or water-proof soles if walked on; leather is not adequate. If hands must be immersed, use rubber or neoprene gloves; use safety goggles where needed. For industrial use only.
