A rusty chain can make any project look old and neglected. Getting that chain sparkling like new can not only spruce up a project, but it can also add value to a home or simply make an old bike look newer. Keep in mind that not every rusted chain is worth cleaning. If the rust has been allowed to pit the metal, then even though it may be possible to get the rust off, the chain itself may never look good again, since its structural integrity may have been compromised. But assuming your chain is not too badly damaged by rust, then with the right household ingredients and just a little bit of elbow grease, you can brighten almost any chain and make it look almost like new again.; here's how.
Instructions
1. Remove the chain from whatever it is attached to, if at all possible. This allows you greater access to the chain. Cover your work area with newspaper or plastic to protect it.
2. Soak your chain in full-strength Simple Green for half an hour (see Resources below). Make certain that the Simple Green solution covers the chain completely. After half an hour of soaking, use a stiff non-metal brush to scrub the chain. Take your time and don't be afraid to use a little elbow grease. Rinse with plain tap water.
3. Make a paste of fine, clean sand and water. Buy the finest grit sand you can. Add just enough water to make a thick paste with the sand and use a cloth to rub the sand paste over any stubborn rust spots that remain. With a little patience and a bit of elbow grease all remaining rust spots should come clean with a sand paste rub. Wash the chain thoroughly with tap water, making certain that you have removed every last grain of sand.
4. Spray the now clean and shiny chain with WD-40 to protect it and to keep it shining like new.
Tips Warnings
Do not rub the sand paste so hard that you destroy any finish that remains on the chain. While it is probable that the rust already removed the majority of any coating the chain originally may have had, there is no point in making matters worse by rubbing off any remaining coating if it is not necessary.
Make absolutely certain that you rise out all sand after cleaning.
