Rust Remover for Concrete Buying Guide
Apart from learning about the best quality products on the market, you also need to know what you should look for before buying one. So, here are a few things that you might want to consider.
1. Types of Removers
Knowing about the type of rust remover is an essential factor when you are buying one. It also helps you to understand which one to get for concrete surfaces.
The available removers on the market fall under three main categories- chemical removers, rust converters, and eco-friendly chelating agents. Let's have a quick look at them.
a. Chemical Removers
These removers are mainly used for commercial and industrial purposes. However, you can also find some suitable for home use. They work fast on heavily stained surfaces and give them a shiny new look.
Chemical removers can be acid-based, powered by sodium hydrosulfite, and petroleum-based.
The acid-based liquid formula contains approximately 30% of hydrofluoric, hydrochloric, oxalic, acetic, nitric, and phosphoric acid. One remover doesn't include all the acids; check the product's ingredient section to know what it has.
The acid removers work fast, and most agents don't require scrubbing or rubbing unless the stain is very heavy. However, you need to be extra careful about your safety while using them.
It is also recommended not to use it on delicate surfaces like fiberglass, painted walls, plastics, steel, or aluminum surfaces.
Conversely, the powered sodium hydrosulfite and petroleum-based ones take a bit longer to act. You may also need to scrub the surfaces while working on heavily rusted planes with the powdered removers.
Although you have to wait for some time while using these products, they are more suitable for home use and can be the ideal solution to your indoor and outdoor stained surfaces.
b. Rust Converters
Converters are used when the rust stains on a surface are way too much for a remover to wipe off completely.
The water-based agent doesn't entirely remove the rust. Instead, it converts it into a black polymer coating that provides further protection to the surface.
And it can be used on concrete, railings, decks, vehicles, and other equipment made of metal.
c. Chelating Agents
Chelating agents are considered more eco-friendly and are gentle to the surface applied as well. It effectively cleans hard planes and corrosion stained tools and equipment.
The formula works by engaging in a chemical reaction with the rust, which effectively removes it and offers further protection by forming an inert coating.
And you can use it on almost every kind of surface, from concrete and metals to tiled ones.
While buying a cleaning agent to get rid of the stubborn rust from the concrete surface, first check whether the product works on concrete or not.
Although most rust removers are multipurpose and work on various surfaces from metal to fiberglass, you need to look specifically if it functions on concrete or not.
Else, you may end up spending money on a product that won't make any difference to the stains on your concrete or even cause damage to the surface.
3. Ease of Use
Well, it's helpful if you check the user-friendliness of the product before buying. And by the ease of use, we mean how easily you can perform your cleaning job with the product; whether it requires scrubbing after applying or if it needs any extra gears or simply spraying and rinsing will do the job.
Best Rust Remover for Concrete comes in both powdered form and liquid formula. While some require mixing and rubbing, with others, just spraying is enough. Also, it depends on the level of your rust stain and cleaning area.
If you need heavy-duty cleaning, get a potent liquid formula that needs only spraying and washing. You can also get one in a convenient spray bottle, which requires spraying on the stain only.
It is a common belief that all chemical cleaning agents are toxic to the environment. Well, no. Nowadays, you will find more environment-friendly and biodegradable products on the market than toxic ones.
We are not saying all removers are non-toxic. No, that cannot be true, as the removing mechanism is entirely a chemical process.
So, it is crucial to know if your remover is safe to use around plants and grasses because you don't want to cause any damage your garden or in the long term to your health.
Besides knowing if the product is eco-friendly, you need to consider if it is safe for your health.
We would recommend you to avoid using those formulas that produce potentially harmful volatile fumes. And always take proper safety measures while working, even if it says it's safe.
Most rust removers are versatile, and they work effectively on different surfaces. However, some products work on specific planes. Getting a versatile cleaning agent is always a smart choice.
Along with removing stains from your outdoor concrete surfaces, you can also use a multipurpose product to clean metal tools, indoor surfaces, fences, and even painted walls.
Otherwise, you may have to buy different sets of agents for other purposes, which will eventually lose its potentiality as you will be using only a few ounces of it.
It's also essential to check whether the product is economical or not. Some products can be expensive and may seem overkill for house use only.
However, it may be designed to last long and only needed in small amounts to dissolve the heavy stains.
Conversely, cheap cleaning agents may cost you more as you need to use them in bulk to eradicate the stains. Also, cheaper products tend to harm the surfaces, causing you, even more, to repair them afterward.
