What chemical can be used to remove rust?
The old standby rust remover chemicals contain either phosphoric or hydrochloric acid to dissolve the rust. They're harsh chemicals that give off some pretty intense fumes, so suit up with rubber gloves, goggles and a respirator. Find them in the paint department at any home center.
Rust, as it turns out, contains hydroxide ions . The sullphenic acid is said to break down the rust. The acetic acid content in vinegar is supposed to be the helpful hand that makes vinegar remove rust. I soaked the blade of a knife in white vinegar for 2 hours.
- WD-40 helps remove rust by breaking down the bonds between metal and rust. Spray the rusted surface with WD-40, enough to thoroughly soak the area. Spray another application of WD-40 on the surface and let it sit for five to 10 minutes. Use sandpaper to remove any remaining rust.
- Soak the rust-free object in the solution for approximately 10 minutes to neutralize the acid in the vinegar. Next, scrub the object with the abrasive item once more if needed to remove any remaining rust, and then rub it down with a pad soaked with denatured alcohol to remove any excess moisture.
- Whenever you get iron, water and oxygen together, you get rust. So the best way to prevent it is to keep them apart; that's what paint does, or the spray-on wax and oil coatings that the car protection companies sell. Keep your tools dry; wipe down your bike after a ride; keep the water away and it can't rust.

- Rust-Inhibiting and Anti-Corrosive Metal Primers. When looking for a rust-inhibiting metal primer, please check that the product states clearly that it offers this.

Try dipping aluminium foil in the vinegar and using it as a brush to scrub off the rust. It is less abrasive than steel wool, but will still do the trick in removing the rust. You can use regular vinegar and simply allow your rusty metal objects to soak in it for up to 24 hours before rinsing.
- Use white vinegar. The vinegar reacts with the rust to dissolve it off of the metal. To use, soak the metal in white vinegar for a few hours and then scrub the rusty paste off. If the object is too big to soak directly in the white vinegar, pour a layer over the top and allow it time to set.
- If you've got rust on clothing it can be removed with either white vinegar or lemon juice.
- Lay the clothing or fabric out on an old towel and pour a small amount of white vinegar directly on the stain - or rub a cut lemon half on the stain.
- Saturate it thoroughly, then blot it with a clean white towel.
- In the event that your stainless steel utensils do have rust on them, follow these instructions to remove it.
- Mix 1 tablespoon of baking soda in 2 cups of water.
