Guide to Buying the Best Rust Remover
Can I use a rust remover on my car?
Some rust removers can be used on cars. Many of today’s products are made to not damage any other surface and to only act on rust. This means that if rust is present on the chassis, the product will not affect the paint around it. On automotive parts such as nuts and bolts, a rust remover can act to remove surface-level rust, which might prevent the parts removal process.
Is it safe to use a rust remover with no gloves?
Many rust removers are not safe to use without minimum safety gear such as protective gloves. Other products are only made to be used with no gloves at all, such as those which are non-toxic. However, most users should wear gloves, especially when having to scrub or clean out the applied formula from the metal surface.
Can a rust remover remove rust from my bathtub?
A rust remover can act on all types of surfaces. On a basic level, it does not know which surface it sits on and it only acts on rust.
How long does a rust remover need to act?
A rust remover is typically applied for at least 2 minutes. Depending on the levels of rust, it might need to stay on the surface longer. However, it is not recommended to leave the product act for a long period in the beginning.
How long will my rust remover last?
Most rust removers can be used for multiple applications. Concentrated solutions can even be transformed into gallons of rust removing formula, simply by adding water. According to the surfaces planned to remove rust from, products should be able to cover them at least a couple of times.
Is a rust remover flammable?
Most rust removers are flammable. Even non-toxic solutions can be flammable. Since most of them are packed in plastic containers, it is recommended to recycle the packaging and avoid contact with direct heat sources.
How to choose the best rust remover
Choosing the best rust remover is not as complicated as many think. Most products offer some results. The difference is made in the time the product acts and in the ingredients, it uses for this purpose. There are various solutions to consider at this time and the following buying guide should be a good start.
Concentrated vs non-concentrated formulas
There is various type of liquid rust removers. They can come in a concentrated formula or in a formulation which doesn’t need added water. With these 2 options in kind, users might be unsure of which path to choose.
Both versions are equally reliable. However, those who might be looking to save money, which are the people who need to deal with rust on multiple occasions, can find the concentrated version better. As seen with the products above, a few concentrated formulas can even offer 16 gallons of rust remover. Unlike many other similar products, rust removers are among the solutions which are simply dissolved with water.
Those who plant to purchase a concentrate also need extra containers to prepare the rust remover. It is best to use containers with lids for small objects such as auto parts. But for safety reasons, storage should be made in bottles with closed caps and even with proper labeling. Both the concentrate and the new formula can be equally harmful and they need to be kept away from the reach of children.
Chemicals vs. organic ingredients
There is a growing trend of organic ingredients to be used in the best products. However, there are not too many products which use entirely organic compounds. As seen above, only a handful of products come with all-natural ingredients.
Interestingly, many organic ingredients are only sourced from vegetables and fruits, through fermentation. This makes them considerably better for the environment. They are also non-toxic. The main benefit of organic ingredients is that they do not harm the skin in case of contact. They also come with no odors or fumes.
As a result, even if they cost more, organic products can be used safely indoors, without necessarily benefiting from the best ventilation. They are also safe for the environment. Those using such products often might need to look towards such formulas which come with a reduced impact on the environment. One such place could be the mechanics’ shop, were rust is deal with daily.
Applying the rust remover is not complicated at all. Sprayers seem to be the easiest solution to work with. On the hand, most of these products are only packaged as a normal liquid and they need a sponge or a cloth for application. It is imperative to ensure there’s no direct contact with the hands with these liquids. The same principles apply to the powder formulation.
However, even sprayed rust removers need to be wiped after a few minutes. It’s one of the reasons why protective gloves should be worn. But even protective gloves are not safe and it is recommended to read the full safety instructions before using such products for the first time.
Liquid vs. powder solutions
As seen above, a few products come in a powdered form. They are not better and they are not worse than typical rust removers in a liquid form. However, they have a set of strengths which makes them unique. A powdered solution usually requires a bit of scrubbing. While effort is needed in their application, the formula is directly applied on the rust and not beyond it, which can be the case with a few spray rust removers.
Safety gear and other safety considerations
In terms of safety, most accidents happen when dangerous rust removers come in contact with the hands or with the eyes. A quick rinse with clean water is the first step towards dealing with such problems. Drinking the solution is even more dangerous.
Some brands go as far as to recommend wearing breathing masks. They can protect users from inhaling fumes and strong odors. At the same time, even safety glasses can be handy, especially when starting to scrub the metal surface. Even products which are made with non-toxic ingredients should be used with care. Some products might even react when being mixed with other formulations. One of the areas which need better information is telling users that these rust removers should never be mixed between them.
Rust removers might require protective gear or they might not. However, all of them can remove rust at different levels and in different periods. Most users can benefit from simple solutions which allow them to quickly remove rust at home.
Dealing with rust on vehicles, swings, the washing machine or in the drain is easier with such products. Some products are more exposed to elements which favor rust formation, such as high humidity. This is why some products are made to offer protection against rust formation.
The products are generally affordable. They can last for a long period or they can be applied on large surfaces. Since they act in a couple of minutes, it is not advisable to leave the location as the formula is then wiped with a wet cloth or paper towels. Results come fast with the products above and even if they do not affect nearby surfaces such as decorative elements as chrome or paint, it is still advisable to only apply the product on the rusty areas as much as possible. The best results should be visible after the first application, even if older rust marks may need another go.
