What is galvanized steel?
Galvanized steel has a protective coating of zinc, usually achieved by dipping the metal in zinc through hot-dip galvanizing. The purpose is to prevent the metal from rusting. Some metals are galvanized, also known as electro-galvanized, which uses an electric current to apply a thin layer of zinc to the metal. Since the zinc layer is much thinner, this method usually doesn't provide enough protection against rust.
You can try five materials such as toothpaste, toilet bowl cleaner, carburetor cleaner, WD-40 anti-rust lubricant and copper rubbing paste
Use a towel with the appropriate material to wipe, this way is simple and convenient, anytime and anywhere you can carry out this "work". Such as rubbing copper paste and carburetor cleaner, etc., have a certain degree of corrosiveness, in the beginning of the operation before or wear a pair of gloves is better.
First, toothpaste
Although the effect of toothpaste is obvious, but in the face of the stars and dots of stubborn rust is also at a loss.
Second, toilet bowl cleaner
Toilet bowl cleaner when wiping the effort spent than toothpaste is much smaller, the actual effect is not bad, the chrome strip basically restore the brightness!
Third, WD-40 universal rust inhibitor
WD-40 antirust agent it has a strong surface affinity for metal and permeability, can penetrate into the metal pores 100% exclusion of water and moisture, the formation of a very thin dense protective film to isolate moisture and air, an effective solution to the metal "from the inside out" of the rust problem. Perhaps its greatest function is to "prevent rust" rather than "remove rust" as we need in this case. So after use, you will find that many traces of the body bright stripes are not removed.
Carburetor cleaner
Carburetor cleaner to remove oil stains, glue stains and other stubborn stains, you can use it to remove. But need to pay attention to the problem of its strong corrosive, the car paint also has a certain impact, so in the operation of the time must not be sprayed on the car paint. As the carburetor cleaner is not very viscous, in the chrome bright strip can not hang, so you need to spray several times, but the effect is still not obvious, rust removal is not obvious!
Five, rubbing copper paste
Copper rubbing cream on the vast majority of metal materials on the rust has a very good removal effect.
The above five rust removal products in addition to toothpaste, basically have a certain degree of acidity or alkalinity, which will lead to chrome plating or even fall off after a long time. But the price is relatively cheap, but will corrode the bright strip, time long chrome layer will lose the original shiny.
It can be said that the restoration work is very complicated, rust removal is always the second choice, buy quality galvanized steel coils and sheets products from reliable steel suppliers, you will not encounter this trouble.
