Why is SpaceX using methane?

SpaceX is focused on developing re-usability technology for their rocket lines. Traditional rocket-grade kerosene produces residue (a process known as ""coking"") when it burns. Methane fuel burns cleaner so there is no residue build-up which means engines can be re-used more times without refurbishment.
