If you’ve been lubricating your chains often, you may notice some grease and tackiness on the chains. To fix this, use a good quality degreaser.
Put on a sufficient amount of degreaser on a clean cloth and wipe off the chain. Rub vigorously for stubborn stains.
If the grease is too much, you can soak the entire chain in the degreaser for about 20 minutes. For this, fill a bucket with a degreaser and soak the chain. After a good 20 minutes, wash off the chain with hot water. Soaking it will remove any remaining grease.
Now that the chain is grease-free, we can move on to removing rust with one of the three solutions mentioned earlier.

While rubbing off the chain, the rust may accumulate in the abrasive or steel wool. So, you can wash off the abrasive in hot water to remove the rust build-ups. Soak it in lime juice again. Then continue rubbing the chain. Once you are done removing rust from a particular area, make sure to rinse it off then wipe it off with a clean cloth or paper towel.
After removing the rust from the entire chain, make sure to wash it at least once with hot water mixed with a small amount of dish soap. Then, rinse it off with clean water.

This method is excellent for removing stubborn and heavy rust formation. Spray the solution directly on the chain. Spray more on the rusted areas. Wait for some minutes to let the solution soak in. Now, all you have to do is take a wire brush and brush off all the rust.
Once you have removed all the rust, wipe the chain with a clean cloth or rinse it.
