ABSTRACT OF THIS DISCLOSURE A method for removing furfural-derived coke from metallic surfaces by heating in an oxygen-containing gas, such as air, for a time and at a temperature sufficient to change the crush strength of the furfural coke to a point which will permit easy removal of such coke, without such an evolution of heat that the metallurgical properties of said metal surfaces are undesirably changed.
