This chain cleaner is very simple to use and seems to do a good job of cleaning the chain, judging by the state of the liquid after I've used it. Good price also.
Do you want a clean chain? this will get it clean. Don't buy a cheaper alternative like I did first of all from Lidl. This is way better
It's a really good tool for cyclist lovers. Fast apply on the chain which looks pretty cool after cleaning. Very happy
