Q: Does Rust911 Industrial Concentrate differ as compared to the other rust removers?

A: The Industrial Concentrate works essentially the same as the Rust911 RTU except we provide very concentrated solutions and you must add water to it before you use it.

Q: How do you use the Rust911 Concentrate or RTU?

A: The RTU is to be used as supplied and the Concentrate must be diluted 8 oz./gallon of water prior to use. Both of them can be used in continuous spray or immersion applications. You can't spray either RTU or concentrate onto the part and let stand. It must continuously be sprayed onto the part until the rust has been removed.

Q: Does water quality, hard or soft water, effect the performance of the Rust Removers when added to the concentrate?

A: It is always best to use distilled, softened or other treated water. But you can use regular drinking tap water. The hardness in waters in certain areas may be extremely high and the hardness may deplete some of the activity of some of the ingredients such as chelants, surfactants, etc.

Q: How does temperature of the fluid effect the rate of rust removal?

A: Rust911 rust remover solution can be heated up to 160 F. This will greatly accelerate the rust removal process. Note: If you place large mass cold cast iron/steel parts into a hot bath, the temperature of the part will cool the bath and have to come up prior to accelerated rust removal.

Q: What percentage of water and concentrate should the industrial rust remover be mixed at to work properly?

A: The ultra concentrate mixed at 8 oz./gallon is equivalent to the other rust removers as they sell it to the public.

Q: Can water be added directly into the industrial concentrate rust remover?

A: Yes. our solution is very miscible and easily mixed into either hot or cold water. Use hot water to accelerate the rust removal process.

Q: How do you know when the Rust911 is almost used up?

A: The solution will turn very black and non-translucent. You can use the solution until it no longer removes rust.

Q: Why would you purchase the industrial concentrate over any RTU solutions?

A: the total volume of the concentrate as it is shipped to you is about 1/10th of the RTU. Why should you pay to ship water when you can add your own water from your house, etc.

Q: Does Rust911 RTU remove the same amount of rust as other rust removers?

A: Rust911 RTU will remove at least the same amount of rust as other rust removers. Based on side-by-side rust removal testing.

A: No, not at all! In fact, Rust911 will remove rust and black oxide and in addition brighten copper/brass and is much less expensive.

Q: Does Rust911 deteriorate or harm plastics, rubbers, paints or surfaces of the metals?

A: Rust911 will not deteriorate any plastics, rubbers, paints. If you are concerned, please try it on a small section of the part prior to fully immersing it. It should be also noted that using Rust911 on polished high carbon steels may cause a slight discoloring of the metal. This can be removed easily if it is not allowed to dry and you re-immerse in new fresh 10% solution

Q: Will Rust911 work on removing rust on interior of gas tanks

A: Yes! Remove any gas from tank, wash with non-caustic detergent, rinse and pour in 8 oz./gallon water. Let stand until rust has been removed and rinse with warm water. Rust911 can be re-use over and over until it turns dark black in color. After de-rusting you can add isopropanol into the tank and swishing around and pouring out will remove any left over water.

Q: How do you dispose of the spent Rust911 Rust Remover?

A: Our Rust Remover is non-hazardous and should be disposed of according to local disposal regulations. Please note that the rust remover may pick up contaminants during the de-rusting process, and if you suspect anything, make sure to test prior to disposal.

Q: How do I remove rust from parts that cannot fit into a bucket or any other container?

A: One of the best ways is to use a plastic sheet, bucket, small submersible pump, garden hose and a sprayer. Drape the plastic sheeting under your part and fasten it so it will flow the water into a bucket. Install the pump in the bucket and half fill the bucket with Rust911 Rust Remover. Suspend the sprayer end so that it sprays solution onto the parts that you want clean. The spray water will be collected by the tarp and re-directed back into the bucket to recirculate back onto the part. You may have to relocate the sprayer to cover all areas.
