How to remove the rust on the galvanized gi pipe?

Most buildings and homes feature the use of steel pipes. You’ll find them as railings, guardrails or conduits to carry electricity, gas and ventilation. These steel pipes are susceptible to rust as a result of moisture. In order to maintain its integrity, we will teach you how to solve the problem of steel pipe rust.


1. Use white vinegar. Vinegar can chemically react with the rust on the metal to decompose it. You can soak the metal in white vinegar for several hours, and then use it to wipe off the rust. If the item is too large to be directly immersed in white vinegar, you can pour a layer of white vinegar on it and let it set. You can also dip a rag in vinegar and wipe the metal.


2. You can soak the aluminum foil in vinegar and use it as a brush to scrub the rust. Compared with steel wool, aluminum foil is less abraded, but still has the ability to remove rust. You can use ordinary vinegar, soak the rusty metal in the vinegar for up to 24 hours before cleaning it. This method does not require too much scrubbing effort.


3. Try lime and salt. Sprinkle salt on the rusty area, cover it thoroughly, and pour the lime juice on it. Try to use as much lime juice as you can, and let it sit for 2 to 3 hours before scrubbing the mixture. Use the rind of the lime to wipe off the mixture. The lime peel should be enough to remove the rust layer without further harming the metal. You can also substitute lemons for limes.


4. Make a paste with baking soda. Mix the baking soda and water until the mixture is thick enough to spread on the metal. Give it some time to set before washing it off. You can try using a toothbrush to brush off the baking soda and then rinse with water. You can dilute the baking soda with water as you like. There is no fixed mixing ratio for this method.


5. Use potatoes and dishwashing detergent. Cut the potatoes in half and cover the cut with dish soap. This will chemically react with the rust layer, making the rust layer easier to remove. Place the potatoes on the metal and let them sit for several hours. If you want to reuse it, you can cut the used end back and apply more dishwashing detergent to let it penetrate the metal for a longer time. If you don’t have dishwashing detergent, you can cover the potato cuts with baking soda and water.


6. Use chemical rust remover. There are many different chemical agents that can decompose rust. They are usually made of phosphoric acid or oxalic acid, which can harm the skin if directly touched. Please take protective measures when using chemical agents to decompose rust. The usage of each product is different, and the instructions on the derusting product must be followed.
