Checking the chain carefully.

Once you remove the chain, carefully examine it. If the rust is heavy and you notice that the chain is worn out, it is better to replace it with a new one. However, if the chain is new, but the rust has accumulated due to other factors, you can continue with these steps.

Using a degreaser

If you’ve been lubricating your chain often, you may notice some grease and dirt on the chain. 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.

Soak it in lime juice or similar solution 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.
