"Gave this a go last night... works a treat.... doesn't smell, no need for gloves and works as well as the ads show! This is the result of a 3hr soak on a brake disc and a wipe down with a rag... and post an overnight soak all rust has gone! Great stuff"
~ James Sparkes, Sydney (Disc brakes- Ferrari Dino)
"I'm an old bike restorer and I've tried them all. This is seriously good s***. I'm a sceptic about most claims by manufacturers but this stuff impressed me"
~ Allan Baggs, QLD
"Absolutely amazing stuff this is! Gets into all the nooks and crannies nothing else can and the results speak for themselves. Since I got onto it and proved the effectiveness of it, many of my friends and now work colleges including motorbike and car restorers are using it with the same amazing results. And no I'm not getting paid to say this, it is just a great product. 2 thumbs up"
~ Steve Nenke, SA (Motorcycle seats)
"After 24 hours in the bath, rinsed in hot soapy water, dried, then coated in vegetable oil and placed in the oven and heated. As good as new!"

No. Metal Rescue™ will penetrate oil and dirt. However, it’s recommended to pre-clean your parts before applying Metal Rescue™. Detergents are more economical and are designed to remove various contaminants. This will also speed up the process of rust removal and extend the life of the Metal Rescue™. Cosmoline, heavy greases, and similar materials should be removed prior to de-rusting.
Metal Rescue™ will remove iron oxide (rust) from ferrous-based substrates in 5 minutes to 24 hours depending on the degree and age of the rust. It will remove zinc phosphate, bluing, browning, and other oxide finishes in about 20 – 40 minutes immersion time. It also brightens copper and copper based alloys such as brass and bronze.
Metal Rescue™ will not remove anodizing, chrome, nickel, powder coating, and paint as long as the paints do not contain metal oxides and are intact. If rust formed behind the paint, then Metal Rescue™ will remove the rust from behind the paint and thus take the paint along with it. If in doubt, check a small section of part prior to use.
Yes, Metal Rescue™ will not remove or harm the vast majority of paint coatings. However, if there is a layer of rust under the paint some of the paint coating will be lost as Metal Rescue™ removes the rust. Also, some paints (and inks) may use iron oxide pigments (usually orange or red). Since Metal Rescue™ has been engineered to remove iron oxide, it may dissolve the pigment in these types of paints. It is always best to test on a small section or hidden area prior to use.
Metal Rescue™ is a rust remover designed for iron and steel. It is safe on metals other than iron and steel as long as they are not left in a Metal Rescue™ soak too long. Metal Rescue™ will remove some oxides from copper, brass, nickel and certain aluminium, however, immersion time is critical. The length of immersion time is dependent upon the amount of oxidation present and alloy composition. It is recommended that the following metals be checked approximately every hour so as not to damage the surface under the oxidation layer: aluminium, brass, copper, chrome, gold, lead, nickel, silver, titanium, tungsten, solder or solder points.
No. It will not harm rubber, plastic, clothing, glass, and other surfaces that are unharmed by water alone. However, as with any materials soaked in a liquid, do not soak these materials longer than you would have them soak in water.
Metal Rescue™ may leave a black film on some parts. The black is from iron oxide II, often referred to as black oxide. Black oxide is a corrosion inhibiting film that is a more stable state of oxidized iron. It is not detrimental to the metal surface and is only cosmetic in nature. It can form on certain steel alloys and high carbon steel when left in Metal Rescue™ for longer periods of time. For these metals, reducing the time that the part is immersed in the liquid will minimize the black film. Much of the black oxide film can be removed simply by rinsing with mild detergent or wiping with a cloth. Also, it is best to remove it immediately after removing parts from Metal Rescue™ and before the parts dry. The black oxide becomes more difficult to remove for parts that have soaked for long periods of time. It is best to soak rusted parts only as long as needed to remove the rust.
Some steels may develop a dull grey finish on polished surfaces. This is attributed to a phosphate-like coating formed and can typically be removed using abrasive pads or similar substances. This can be minimized by checking the parts and removing from the bath when rust has been removed. Leave parts immersed in Metal Rescue™ only as long as needed to remove rust.
Metal Rescue™ is not recommended for use on magnesium or magnesium alloys.
Metal Rescue™ only works in the liquid form. When sprayed on a surface, Metal Rescue™ will dry before de-rusting can be completed. However, Metal Rescue™ is effective in removing rust if continuously sprayed onto the surface until the rust has been dissolved. Typical operations are continuous spray washers with the Metal Rescue™ fluid being re-circulated. The best method for using Metal Rescue™ is a bath or soak.
A smooth absorbent material can be soaked with Metal Rescue™ and applied to the rusted area. The area will need to be covered with plastic film to prevent evaporation and drying. When the surface is de-rusted, rinse with water and use a brush or sponge if necessary. Another method for less severe rust is to scrub the rusted surface with Metal Rescue™. For optimal results, the key is to keep the rusted area saturated – Metal Rescue™ was designed to be used a soak, using this alternate method requires that the liquid remain in contact to work properly. While this is not the intended form to use Metal Rescue™, it is still much safer than scrubbing with acids and alkalis.
Five litres of Metal Rescue™ will remove approximately a 300g of dry rust. That is equivalent to removing rust from approximately 180Kg of moderately rusted steel. For reference, 5 litres of Metal Rescue™ will remove rust from approximately 1.25 square metres of moderately rusted steel. If any of the Metal Rescue™ solution evaporates, simply replace it with fresh tap water to original level.
The bath will turn completely black and rust removal rates significantly decrease. The specific gravity will change from 1.02 to 1.06.
One way to determine when Metal Rescue™ is used up is to measure specific gravity. There are many ways to measure specific gravity. One way is to use a hydrometer. They are easily available and cost between $10 and $30. They are commonly used for home brewing and wine making, and also used by people who keep salt water aquariums. Additionally, most manufacturing facilities with labs or chemicals have several ways to measure the specific gravity of a liquid.
Metal Rescue™ will continue to work even after changing color. The liquid turns darker due to the iron oxide particles removed from the iron/steel. Upon de-rusting a heavily rusted item, the bath will turn darker. Metal Rescue™ will cease to be effective when the liquid turns completely black.
Yes. The rust particles from the part are actually absorbed into the liquid, hence, the change of color from clear to black. Typically, there will be only a small percentage of rust particles on the bottom of the tub itself compared to the amount of rust removed from the object(s). Removing/filtering loose rust from Metal Rescue before reuse or storage will prevent the active ingredient in Metal Rescue from being exhausted. This will not reactivate the used Metal Rescue but instead preserve the corrosion removal properties.
If left in too long (over 24 hours) a darker film may be noticed on the metal. The dark appearance is from iron oxide II, often referred to as black oxide. Black oxide is a corrosion inhibiting film that is a more stable state of oxidized iron. It is not detrimental to the metal surface and is only cosmetic in nature. It can form on certain steel alloys and high carbon steel when left in Metal Rescue™ for longer periods of time. For these metals, reducing the time that the part is immersed in the liquid will minimize the black film. Much of the black oxide film can be removed simply by rinsing with mild detergent or wiping with a cloth. Also, it is best to remove it immediately after removing parts from Metal Rescue™ and before the parts dry. The black oxide becomes more difficult to remove for parts that have soaked for long periods of time. It is best to soak rusted parts only as long as needed to remove the rust.
Metal Rescue™ works best when the liquid is in direct contact with the metal. Bulk parts that are lying on top of each other may need to be agitated or moved in order to ensure adequate contact with Metal Rescue™ is made.
Metal Rescue contains no VOCs, solvents, acids or other hazardous ingredients. Spent (used) Metal Rescue is biodegradable and in most locations directly sewerable unless hazardous waste (certain oils, paints, heavy metals, etc.) is introduced into the solution. It is recommended users check local and federal disposal requirements.
Heating up the fluid to 60⁰C will increase the rate of rust removal and reduce rust removal time. Operating temperatures for Metal Rescue™ are 20⁰C to 65⁰C. If too cold, Metal Rescue™ will not work or will take much longer to de-rust.
Move the Metal Rescue™ to a warmer area and let stand to thaw. Once completely thawed, you can use as directed – making sure that Metal Rescue™ is at a minimum temperature of 20⁰C.
Metal Rescue™ is completely water miscible and easily rinsed off. Use warm clean water to rinse off parts and dry thoroughly after.
Metal Rescue™ can be used as a short-term rust preventative. Spray or dip parts with a clean solution of Metal Rescue™, remove and let dry. Simply rinse off prior to painting or other coating. For longer term protection, use Dry Coat™ Rust Preventative spray.
While Metal Rescue™ is “safe on everything except rust”, moderation is always a key, as with anything. If Metal Rescue™ liquid is left in a metal container for a long period of time, two things will happen. 1) The metal container may develop a black film on it due to the formation of iron oxide II, often referred to as black oxide. Black oxide is a corrosion inhibiting film that is a more stable state of oxidized iron. It is not detrimental to the metal surface and is only cosmetic in nature. However, the main concern with this is that it will use up your Metal Rescue™ liquid. 2) As a metal (metal container) is in contact with Metal Rescue™ for extended periods, carbon can be pulled to the surface, causing the container to become darker. This phenomenon will especially occur with high carbon steel and certain alloys. We recommend using a plastic container when soaking parts in Metal Rescue™.
