The Must for Rust rust remover & inhibitor is designed to provide clean, inert metal surfaces needed for any coating application. It's the simple, effective solution to stop rust and protect metal.

 

The Must for Rust is designed to dissolve rust and oxides from metal surfaces. Chemically, it reverses the rusting reaction and clears away all oxidation from the metal. Also, minute crystals are formed that become integral with the surface molecules of the base metal, inhibiting further oxidation. These deposits are completely inert and do not change the tolerances or the conductivity of the metal. After the rust is dissolved and the Must for Rust has dried, the surface is ready for the next step, whether it be painting, welding, plating, lubricating, etc. Or, simply leave the surface bare and the Must for Rust will inhibit future rust formation.

What is Rust or Oxidation?

Metal rusts when surface molecules combine with oxygen, creating an oxide. It's a simple chemical reaction needing only metal and air. That's why it's so common. But why is there more rust in Florida than Arizona? It's because moist air in areas with high humidity releases more oxygen than dry air. This is clear to anyone who lives in coastal areas, the Great Lakes region or other areas of high humidity. Although rust comes from metal, it's nothing like it's host. It's not strong or dense. Rust is porous like a sponge, and will continue to grow. That's why rust pushes paints and coatings from metal surfaces, and freezes moving parts and tools. Rust contains air because it's porous. This oxygen in rust is enough to continue the rusting process even after the surface is coated with paint, primer, plating, and so on. This eventually leads to coating failure. No matter how carefully the metal is fabricated, machined or packaged, rust can always form.

 

What the Must for Rust is...

...and isn't

red check-box

water based. It can be used full strength or diluted with clean tap water.

bullet

a primer. It doesn't cover up the rust.
red check-box non flammable, unlike solvents and oily lubricants. bullet a converter. It doesn't leave a black coating on metal when used properly.
red check-box environmentally safe, requiring no permits or special packaging. bullet an oily lubricant. After cleaning, the Must for Rust leaves the metal surface dry and inert.
red check-box easy to use - just spray, dip or brush on to dissolve rust. bullet a high VOC cleaner. In fact, it has no VOC's because there are no solvents.
red check-box safe to use - no special ventilation or handling equipment needed. bullet a muriatic or hydrochloric acid, which can be dangerous. It contains low levels of phosphoric acid, a common ingredient in detergents and some foods.
red check-box effective - dissolving medium to light rust in 15 to 30 minutes or less.

Other questions you may have...

How does the Must for Rust remove rust?
the Must for Rust, because it is a low-viscosity liquid, penetrates into every void of a metal surface and dissolves the oxidation through chemical action. Then tiny elements (sometimes seen as white crystals) are formed and become integral with the surface molecules of the metal to resist rusting again. The corrosive agents attack these crystals rather than the metal. These crystals become part of the metal surface and need not be removed for any painting or subsequent operations, such as welding, machining, etc. There is no 'build' as with a paint film, and they are completely inert and do not react with any solvent or vehicle that is found in paints, coatings, and so forth. No gassing occurs with heating.

How do I neutralize it?
the Must for Rust doesn't need to be neutralized on the metal surface. Once it dries, it becomes inert and won't react to temperature or other chemicals.

How long does it take to remove rust?
That's difficult to answer. the Must for Rust cleans most medium to light rust in 15-30 minutes. Variables include temperature, corrosion level of the metal surface and type of metal. the Must for Rust works faster at warmer temperatures on good quality ferrous and non-ferrous metals. Corrosion on some non-ferrous metals like copper, bronze and aluminum is removed in less than five minutes. Metal alloys heavy in iron can sometimes take more than 30 minutes if the surface is heavily pitted.

Will it hurt the paint?
the Must for Rust is water based and contains no solvents, so it won't remove or penetrate paint. If rust is present under a coating, the coating must be removed through mechanical methods before the Must for Rust can go to work. Still, if the Must for Rust overspray is left to dry on paint, it can sometimes lighten the color through the process of de-oxidation of the paint surface. To prevent this, simply wipe excess the Must for Rust off painted surfaces after applying the Must for Rust to the rusted area.

Do I have to wash it off?
No, if you wash the Must for Rust off after dissolving the rust, you're using it just as a rust remover and not as a rust inhibitor. As the Must for Rust dries on the surface of the metal, it protects against the formation of oxides. The only time rinsing is recommended is to wash off dirt or foreign matter after the rust is dissolved. Rinsing is also recommended for some non-ferrous metals.

Can I paint over the Must for Rust?
Yes. When dry, the Must for Rust accepts any primer, paint, coating, plating, welding, etc. Painting over the Must for Rust has two benefits. The first is that the Must for Rust provides a clean surface free of contaminants which allows a secure bond for coating. The second is that when chips or breaks appear in the coating, the Must for Rust underneath the coating will limit the rust to the break. That means that rust won't spread under the
coating and maintenance touch-ups will be quicker and easier.

Do I have to remove it before welding?
No. the Must for Rust helps weld joints last longer. Coatings applied to welds tend to suffer premature failure because the heat of welding has formed oxides that are not removed by hand or mechanical cleaning.

How far does it go?
That depends on how the Must for Rust is applied. When sprayed, one gallon of full strength the Must for Rust can cover 500 square feet. When brushed, 300 square feet. When used in a dip operation, the Must for Rust can last for months, depending on the type of rust and metal cleaned. Eventually, the the Must for Rust in the tank will become contaminated and it's rust removal ability will decrease.

How do we remove the white deposit?
If the solution is too strong, white inhibitive crystals will appear after drying. To remove these, simply apply the Must for Rust, then wipe from the surface. Once dry, the the Must for Rust treated surface is completely inert and does not react with any solvent or paint pigment. When you have sampled correctly and determined the dilution required, there will be no excess of unused chemicals and no neutralizing needed.

How do we achieve optimum results?

bullet

Make sure the metal surface is clean of grease and oil. the Must for Rust is water based, and can't remove rust if oil is present.

bullet

Keep the surface wet with the Must for Rust. When the Must for Rust dries, it stops working. As long as the surface remains coated with liquid the Must for Rust, the rust will be dissolved.

bullet

Work in a warm environment. If the Must for Rust can't be heated, try to apply in ambient temperature of 70 degrees or above.

bullet

When painting on clean metal surfaces, spray a 50% diluted solution on the surface and let dry before painting.
