Rust Remover for Metal

Singerman Rust Remover solution has many uses from Automotive to industrial, to reconditioning, Household Uses, Marine Applications and more.

Singerman Laboratories liquid rust remover is an effective, carefully formulated product, to be used straight from its container without dilution or addition of any other materials. It is completely water soluble, odorless, and non-flammable. It does not produce fumes. It contains no hazardous or highly corrosive mineral acids or toxic volatile acids, such as muriatic acid or phosphoric acid. Non-poisonous, it contains no phosphorus or chlorine or petroleum distillates. It is biodegradable and will not harm the environment. As such, its components are not regulated. The product is only mildly acidic. At pH = 3.7 to 3.9, it is actually less acidic than lemon juice or household vinegar. It is made from materials that comply with the Food Chemicals Codex (FCC) and U. S. Pharmacopeia (USP) specifications. Even so, do not mix it with any other chemicals or household cleaners.

Rust Removal
Singerman Laboratories rust remover safely removes tarnish, rust, and mill scale from carbon steel, mild steel, stainless steel, and cast iron. Singerman Laboratories does not attack the underlying metal. It will not harm plastic, paint, glass, aluminum, copper, brass, nickel, chrome, ceramics, or glazed tile. It will, however, attack zinc, lead and tin alloys, and should not be used on items that contain these metals, such as galvanized steel or pewter. Singerman Laboratories rust remover will also damage genuine marble and plaster. To derust iron or steel with Singerman Laboratories liquid, first remove oil, dirt, and loose rust. Place item in an open container or tank made of stainless steel, glass, polyethylene (non-heated tanks), fiberglass plastic, or steel lined with plastic or rubber. Do not use a galvanized container. Pour in Singerman Laboratories rust remover to completely cover the item to be derusted. Allow item to soak until derusting is complete - 15 minutes to several hours, depending on severity of rust. To speed derusting, heat the solution (but not to boiling), brush away loose rust sludge every 20 or 30 minutes. Rinse derusted item thoroughly with tap water. Dry. If not to be painted, lightly oil the rust-free item to keep it free of rust.

Waste disposal
All of the ingredients of Singerman Laboratories are naturally occurring substances and are widely distributed in nature. They are completely and rapidly biodegradable, essentially non-toxic, and do not build up in the environment. However, it is the user's responsibility to know the appropriate local, state, and federal regulations for waste disposal of this product. These regulations take precedence over any advice offered by Singerman Laboratories.

Speed & Endurance
Singerman Laboratories may be used over and over to derust many items until its strength is depleted. Laboratory tests were conducted using 1/8" x 5" x 8 1/2" test panels of hot-rolled carbon steel. The surfaces of these panels were encrusted with heavy rust 4.5 to 5.0 thousandths of an inch thick. The rusty test panels were derusted in batches of 7 panels spaced 1/4" apart. The test used 2 3/4 quarts of Singerman Laboratories rust remover, which was not changed or refreshed during the test. At room temperature (77-80oF), the first batch of panels were rust-free in 1.5 hours. As the strength of the Singerman Laboratories rust remover is depleted the derusting rate slows so that the fifth batch of test panels required 8 hours for complete rust removal. At the same time the acidity of the Singerman Laboratories rust remover dropped from pH = 3.8 to pH = 6.5 (nearly neutral). At this point we judged that the rust remover was spent. Based on this laboratory data, we calculated that one gallon of Singerman Laboratories rust remover will derust 30 square feet of steel having rust 4.5 to 5.0 thousandths of an inch deep on its surface. To put this in perspective, if one gallon of Singerman Laboratories rust remover is spread over 30 square feet of steel, it will be only 0.053 inches deep, that is, 1/20 of an inch, and this depth will be sufficient to remove rust of the same thickness as on our test panels.

Other rust removers
We compared the effectiveness of a thickened Singerman Laboratories to that of Naval Jelly, which is basically thickened phosphoric acid (which, by the way, is classified as a poison under the Federal Caustic Poison Act). We thickened the Singerman Laboratories in order to get as fair a test as possible against Naval Jelly. Actually, liquid Singerman Laboratories removes rust significantly better than the thickened Singerman Laboratories used in this test.

Rusty sheet-metal test panels were cleaned of dirt, dried, and weighed on an analytical balance. One panel was coated with Singerman Laboratories. Another was coated with Naval Jelly. The panels were allowed to hang vertically in air for one hour. After washing in water and drying, the panels were again weighed. The loss in weight of the panels corresponds to the rust removed from them. For thickened Singerman Laboratories, the panel's weight loss was 2.33%; for Naval Jelly the panel's weight loss was 1.96%. In this test, thickened Singerman Laboratories removed more rust than did Naval Jelly. Repeats of this test gave the same results. Liquid Singerman Laboratories is even more effective in removing rust than the thickened version.

In addition to phosphoric acid, another chemical that is used to remove rust is hydrochloric acid, sometimes called muriatic acid. We obtained a commercial sample, supplied as a concentrate containing 20% hydrochloric acid. We diluted the concentrate with water according to label directions and immersed seven rusty test panels in it, and another seven in Singerman Laboratories liquid, for two hours. At the end of the test, all seven of the panels soaked in Singerman Laboratories were clean and free of rust. All seven of the panels soaked in the hydrochloric acid solution remained rusty, with only about half the rust removed.

When we tested the commercial hydrochloric acid rust remover concentrate without diluting it, it removed rust very well. However, the pungent fumes liberated when handling the concentrated acid are very irritating to breathe. In fact hydrochloric acid liquid and vapor are highly toxic and corrosive, and can cause severe burns to all body tissue. Inhalation can cause lung damage; if swallowed, it can be fatal. Hydrochloric acid is listed as a poison under the Federal Caustic Poison Act. If diluted with enough water to make it relatively safe to handle, it does not remove rust very well; if used in concentrated form, it is dangerous. Furthermore, to dispose of the used hydrochloric acid lawfully, one must take into account local, state, and federal regulations pertaining to hazardous waste.

Temperature effect on rust removal
The hotter the Singerman Laboratories rust remover, the faster it will remove rust. As an example, at room temperature (77oF), one of the rusty test panels described above will be rust free after 1.5 hours immersion in Singerman Laboratories. At 194-199oF (Singerman Laboratories boils at 212oF), the panel will be rust free in 10 minutes.

How to Use Singerman Rust Remover

  1. Brush away loose rust and remove oil and dirt.
  2. Place items in a tub, bucket or tank and pour in enough rust remover to completely immerse the rusty items.  (Rust Remover can be brushed on surface, but soaking is more effective.)
  3. Allow items to soak untill derusting is complete.  This process can take a matter of minutes to several hours, depending on the severity of the corrosion.

    If corrosion is extreamly heavy, overnight soaking may be required, and  occasional brushing is helpful.

    Tip:  To speed derusting, heat solution to 170°F (not to boiling) brush away loose rust.  Flash rust can be overcome in a matter of seconds.  (Singerman is ideal for heated solution tanks.)
  4. Rinse derusted item with water and dry.  If not to be painted, lightly oil or cover with inhibitor protection to prevent re-rusting.
