I ride bicycle for recreational purpose. Over time, I noticed that the initially clean bicycle chain will slowly turn black and dirty as the chain picks up dirt from the ground when the bicycle is moving. Thus, I started cleaning the chain once i noticed that the chain is dirty. After cleaning the chain for few times, I find the process to be tedious and slow. Finally, I found a chain cleaner which i am selling here to be a easier and faster way to clean my dirty bicycle chain.

Change your rear gear to the biggest gear first so that it will be easier for you to move the chain through the chain cleaner.
Open the cover so that you can pour the cleaning solution (Kerosene can be used) into the chain cleaner.
Place the bicycle chain into the chain cleaner and replace back the cover.
Start pedaling so that the chain can move through the chain cleaner to start the chain cleaning process.
Continue to pedal until the chain is clean
Pour away the dirty cleaning solution and wash the chain cleaner
Add water mixed with detergent into the chain cleaner and move the chain through the chain cleaner again.
Use dry cloth to wipe dry the chain. The chain should be clean at this stage
Please remember to lubricate your chain after cleaning. Else, your chain will start to rust within a few days.

The chain cleaner when combined with a cleaning solution will be able to remove dirt, sand and oil from your bicycle chain. After cleaning your bicycle chain, your bicycle chain will be clean and shiny. With a clean bicycle chain, you will enjoy a smoother ride and your bicycle chain will last longer.
