This can be done with the bike upright or turned upside-down for easier access to the bike chain.
1/ Crank the bike pedals in reverse to feed the chain around while pouring drops of Eco Fix Oil onto the chain above the back sprocket. This will allow the oil to spread evenly around the entire bike chain and sprockets and at the same time penetrate inside all the chain links where it needs cleaning and lubricating the most.
2/ Once a full even coating is applied, take a cloth or rag and gently hold it around the chain where it runs between the back wheel and crank at the bottom of the bike and crank it backwards again to allow the chain to run through the cloth and wipe off any dirt and grime the oil has dissolved and loosened.
3/ Repeat step 1 application of Eco Fix Oil to leave the bike chain well lubricated and protected.
