In the next step, high pressure cleaning water is jetted from cleaning nozzles 31 and 34 in the cleaner body 11 to clean the coupling faces of the lower mold 3 and upper mold 2 respectively. In the next step, after the cleaning nozzle 31 is lowered and clean the inside peripheries of the lower mold 3 and upper mold 2 while passing in front of the nozzle with the jet of high pressure cleaning water, the inside peripheries of the molds are applied with mold lubricant by a mold lubricant applying nozzle 33.
