Most people who have galvanized pipe ask themselves this question; how to clean galvanized pipe?

Before starting with this, it is required to understand what is and the use of galvanized steel.  Galvanized steel pipe is simply steel with a powerfully bonded zinc coating which prevents corrosion and greatly increases the longevity and durability of the steel. Galvanized steel pipes can commonly be found in sheet metal, gutters, and car doors and hoods.

Although galvanized steel pipe is still strong against rust, it can still get dirty and is best handled with extreme caution. If you protect your galvanized steel pipe and clean it regularly, you can increase its longevity and sustain your facade over a long time.

However, galvanized steel pipes are commonly used in plumbing apps. Places where the metal is exposed to moisture all the time. It is always tried to galvanize a steel pipe that is only handled with a special zinc oxide coating to avoid rusting and limit the pipe’s inconvenience developed by other corrosive elements. Cleaning the galvanized pipe will prolong the service life of the zinc oxide coating.

What is Zinc?

Zinc is a material with enormous ease of use worldwide. Zinc coatings can secure exposed edges and scratches because this element reacts with oxygen more readily than iron in steel.

This is why zinc usually assumes the corrosive force in corrosive environments while securing the steel.

Considering all of the above, we have the possibility of ensuring that galvanized steel pipe is the coating that asserts the greatest durability under any outdoor environment. However, we must understand that zinc coatings save industry and customers hundreds of millions of dollars every year in different apps.

Why does my Galvanized Steel Pipe Rust?

How to Clean Galvanized Pipe

There are numerous components, and about the use of the pipe, the location, and so on, the pipe could rust. It is ideal to understand that nothing is eternal.

First and foremost, we owe the new galvanized metal is a product that is used to create corrugated sheets, gutters, and downspouts. This metal tends to be smooth and can be coated with an oil coating to prevent white rusting or be passive. However, paint applied over this oily or transparent passivation area will quickly peel.

However, alkyd oil paints that can be used on galvanized metal to adhere to it at first will sadly fail quickly. Zinc from galvanizing can react chemically with the alkyd binder in the paint, creating a “soap” film (saponification) on the galvanized metal and causing the coating to peel.

When uncolored galvanized metal is exposed to the atmosphere and left out in the open, the protective zinc coating will commonly oxidize into white rust. This happens until the zinc metal is finally exhausted. Then, the underlying steel will rust. This can damage our tubing.

Although new, this oily/passivized galvanized metal is painted through in cold or very wet conditions, the paint film’s curing is delayed, resulting in wrinkles and loss of adhesion.

What is the Benefit of Galvanized Pipe?

Longer service life and durability

The coating brought about by galvanizing development can last well over 50 years on many rural surfaces and well over 25 years in seriously exposed urban or coastal environments. In the same way, its extended duration will always depend on the level of exposure of the steel to corrosive agents.

Cost reduction

These coatings do not need the care to ensure their characteristics. This is why galvanizing a material is not much more expensive than painting it, as opposed to painting. The painting on galvanized metal is effective.

Great versatility

This development can be applied to different parts of different sizes and shapes, from nuts and bolts to huge structural surfaces such as metal profiles.

High reliability

The hot-dip galvanized coatings can be one of the few steel custody systems that are very well specified by national and worldwide standards; that is why they are simple and are totally and timely controlled.

High resistance and coating

The metallurgical zinc coating of the steel obtained with hot-dip galvanization tends to be very strong against impact and abrasion. This causes by immersion in liquid zinc. The integrity of the parts’ area can be covered both internally and externally, which obstructs the damage caused by damage and scratches in the material.

Step 2

In this development, it will be essential that you buy a chemical pipe cleaner.

This is a product that can guide you through quite a bit of pipe cleaning. A product like this should have the power and effectiveness necessary to remove the rust when you put it in. Chemical for rust removal is available at most hardware stores.

Step 3

In this step, the fundamental thing is to use the pipe cleaner on the pipe. The rules can change according to the pipe cleaner brand you have bought. That’s why you have to follow the rules of the bottle and apply the pipe cleaner. Allow the cleaner to circulate for the time indicated on the bottle.

Step 4

Finally, it requires that you rinse the pipe with water. When the pipe cleaner has circulated in the rust in pipes, you must open the taps into the water rinse the pipes.

After a short time, the water supply in your living space should be less limited.

Frequently Asked Questions

How do I remove corrosion from the galvanized pipe?

Cleaning galvanizes steel pipe tends to be too simple. However, it is important to keep in mind that you have to follow all the previously mentioned steps for everything to be successful.

Will the vinegar clean the galvanized metal?

White vinegar is one of the most effective procedures and the most considerable. It is not toxic, so it is much safer to use than the average industrial solvent.

All you have to do is use the vinegar on a clean rag and, after that, clean the galvanized area. The acidity of the vinegar will react with the metal, trying the area to promote the paint’s adhesion.

Those who have more experience can use other acids. Added sulfuric acid, muriatic acid (also called hydrochloric acid), or acetic acid diluted in water. However, this will require neutralization and much ventilation.

When the coating has come off, the items should rinse to remove the acid and stop the corrosive action. Items that immerse in heat may need to be polished with a wire wheel or a finned disc.

Can you remove the galvanized coating?

The precise answer is yes. Removing a galvanized coating may be too simple, but not in all cases is a requirement.

However, there are opportunities where it is critical. How it discard is considerable because some procedures generate highly toxic fumes or waste products that must be disposed of with care.

Will vinegar damage galvanized metal?

Vinegar, on the other hand, helps the galvanized metal to stay clean as long as you know how to apply the same. You can rust remover with vinegar.

How does vinegar discard galvanized coating?

Vinegar is very effective and non-toxic, so it is much safer to use than the average industrial solvent. All you have to do is use the vinegar in a clean rag or pot and clean the galvanized area. The same acidity of the vinegar will react with the metal. Trying the area to promote the paint or dirt adhesion.

If you are wondering if this would damage the pipe, the answer is no.

Can you polish Galvanized steel?

Galvanized steel is a type of metal that has been coated with zinc. The answer is, “No.” You cannot polish galvanized steel because it does not have a protective coating. The zinc oxide in the galvanizing process protects from corrosion and rusting of the metal. Paint or other clear finish may be applied to protect this type of metal after use, but no polishing techniques can restore its original appearance.

How much does it cost to replace galvanized pipes?

Galvanized pipes cost about $30 per foot to replace. The replacement process for galvanized pipes is a little more labor-intensive than other types of pipes, so expect the price to be higher as well. If you’re going with copper pipes instead, costs will range from $17-$200/foot, and installation time can take up to three days, depending on your needs. If you don’t have any professional plumbing experience, then it’s recommended that you hire someone who does or call in an expert plumber if need be. Additionally, look into what kind of warranty they offer before making a final decision because not all companies are created equal!


As we mentioned at the beginning, galvanized metal is just a type of steel that can avoid corrosion and increase the durability and longevity of the materials when dipped in hot zinc coating.

The underlying steel is solid against oxidation and the accumulation of mineral deposits. However, it still needs regular cleaning and proper care.

Studying how to clean galvanized pipe belongs to the most accessible techniques of optimizing the place of life to make the material look more beautiful and last much longer.

It is feasible to see hot-dip galvanized steel for gutters, sheet metal, stairs, balconies, and car doors and hoods. On the other hand, it also uses to make garden containers, fences, roofs, stairs, outdoor walkways, and much more.
