Replace replication slave after long downtime

I have a mySQL 5.5 server which was set up to replicate to a remotely located slave several years year ago. The slave hard disk crashed many months ago so the master bin-logs have been growing but not being used by any slave. I now want to set up a new slave, so I expect I will need to reset/clear the bin logs before I do. I figure after all this time it is best just to "start again" with the setup. Is this just a matter of turning off replication and turning off bin-logging, and starting again? Will the logs clear automatically? DO I need to manually delete the bin-logs? If so, how safe is this process for the data on the master?
