method 1: use domestic materials to remove rust

1, use white vinegar. Vinegar can react with rust on metal and decompose it. You can soak the metal in white vinegar for several hours and then wipe off the rust with water. If the object is too big to be 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. You can try dipping the foil in vinegar and using it as a brush to scrub rust. Compared with steel velvet, aluminum foil is not worn, but it still has the ability of rust removal. You can use ordinary vinegar, let rusty metal soak in vinegar for up to 24 hours before cleaning. This method does not require too much scrubbing effort.

2. Try lime and salt. Sprinkle salt over the rusty area, cover it thoroughly, and then squeeze the lime juice onto it. Try to use as much lime juice as you can get and let stand for 2 to 3 hours before washing the mixture. Wipe off the mixture with the skin of the lime. The lime peel shall be sufficient to remove rust without further damage to the metal. You can also use lemon instead of lime.

3. Make paste with baking soda. Mix baking soda with water until the mixture is thick enough to coat the metal. Give it some time to set before you wash it. You can try to use a toothbrush to brush off the baking soda and then rinse it with water. You can dilute baking soda with water as you like. There is no fixed mixing ratio.

4. Use potatoes and dishwashing agents. Cut the potatoes in half and cover the cut with dishwashing agent. This will react with the rust and make it easier to remove. Place the potatoes on the metal and let stand for several hours. If you want to reuse it, you can cut off the used end, apply more dishwashing agent, and let it seep into the metal for a longer time. If you don’t have a dishwasher, cover the potatoes with baking soda and water.

method 2: use the goods purchased from the store to remove rust

1, use chemical rust remover. There are many different chemicals that can break down rust. They are usually made of phosphoric acid or oxalic acid and can damage the skin if exposed directly. Take protective measures when using chemical agent to decompose rust. The usage of each product is different and the instructions on the derusting product must be followed. These chemicals usually need to stand for a while and then need to be scrubbed, so be prepared for extra work. These products are more expensive, can only be used for small-scale rust removal work, not suitable for larger rusty items.

2, transformed rust layer. Buy rust conversion agents, they can prevent the expansion of rust area on the metal. Similar to spray paint, rust conversion agent can also be used as primer protection layer. Although it can prevent the rust layer from expanding, it may not be able to effectively remove the rust layer from the metal completely. This method works only if you plan to paint the metal. It will also leave a rough texture under the paint coating, because you just cover the rust with a layer of paint.

3. Use sanding tools to scrape off the rust layer. This method is very laborious, but it allows you to effectively remove rust only by scraping. You can use garage tools, such as screwdrivers, or rent tools from a hardware store. Steel velvet is also easy to use, and you may already have one at home without having to buy it. You can use an electric sander to remove rust from large metals. Starting with the coarsest abrasive particles, it slowly transits to the finer particles to minimize the roughness of the metal. You can use any metal tool to scrape off the rust layer, but remember to use particle sandpaper to smooth out the traces that may be left during the scraping process.

Apply lemon juice to the affected part of the garment, but do not allow it to air dry. Wash off lemon juice and rust with water. Use lemon juice to remove rust and wash clothes as usual. As for heavy cloth with serious rust, in addition to lemon juice, you can also apply salt on the rust layer.

2. Remove rust from bricks or concrete. Mix 7 parts of lime Free Glycerin, 1 part of sodium citrate (available at pharmacy), 6 parts of lukewarm water and enough calcium carbonate powder (chalk) to form a thick paste. Apply the thick paste to the rust area and let it harden. After hardening, scrape it off with a metal tool. If the rust cannot be completely removed, you can use the same method to apply thick paste again.

3. Remove rust spots on porcelain and ceramics. Mix borax and lemon juice into a paste and apply it on the rust spot. Then scrape it off with pumice stone and repeat if necessary. This method can not be used for ceramic kitchenware, because it will scratch the kitchenware. After that, the ceramic or porcelain should be dried to prevent re rusting.
