Why are most of the cleaning products advertisements feature rust stains on clothes, cement and cars? It is in fact obvious that rust stains are very hard to get rid of. When a metal is exposed to air and/or water, it is likely to undergo a chemical reaction in which it is rendered weak and structurally compromised as in the case of a the Mianus River Bridge where rust caused its collapse.
Rust manifests itself as a reddish brown discoloration that is really hard to remove on any surface that it contacts with. Choosing the right and ideal rust remover is very important in order to efficiently remove these nuisances.
The following should be the ideal characteristics of an ideal rust remover:
1.Immediate Efficacy. The rust remover should take effect immediately. This is important because this is in the first place what the products were made for. Well, how can you tell if rust remover is taking effect? For one, once sprayed or applied it should turn the stain into loose salts that can be easily washed away by water. The reaction is all chemical of course and need not be discussed in here.
2. Non Toxic. Since the rust remover is to be used by us, humans, it should not contain any harmful chemicals that pose any risks. Normally, chemicals used in the production of these rust removal products are cream of tartar, baking soda, hydrogen peroxide, which is all safe if used in moderate amounts. There are, however, a lot of rust removers which contain little or even none of these above mentioned chemicals. Most of these commercially available natural cleaning products are safe not only for us but also for plants. Thus they are called organic rust removers!
3. Residual Effect. Just like antimicrobial agents, rust removers should have some kind of a residual effect that sort of protects the treated metal from further rust formation. This effect should give the metal surface additional protection from corrosion reaction products. This process is just like what they do with stainless steels, making metal surfaces “rust proof”. Therefore it should not contain phosphoric acid, which is a known corrosive agent. In other words, it employs the formation of rust instead of preventing it. Well, this is obviously not good, right?
4. Broad Spectrum. The rust remover should be suitable to a variety of products. It should not cause deteriorating effects to certain materials while performing its function. The result should always be towards the positive side and that is rust removal! Certain rust removal products cannot be used on certain surfaces because of certain factors that can be associated with the nature of the material itself.
5. Safe to use for the material. It should not cause further damage to the surface being cleaned. The product should not affect the material’s appearance and would be much better if it can contribute to the material’s aesthetics.
6. And Finally… It should be economical so that it can be availed by people from all walks of life. Money should not be a factor in choosing the right ONE. If we think about it, it is kind of hard to find the right rust remover. But the truth is there really are products which possess almost all of these characteristics. And take note, an ideal rust remover need not be expensive!
