PURPOSE:To kill microorganisms attaching to articles, especially tableware through simple operations by bringing the tablewave to which bacterial spores are attached into contact with a solution of hypochlorite under heating. CONSTITUTION:To kill bacterial spores when washing tablewave using an automatic dish washer including a washing process and a rinsing process, the tablewave are brought into contact with a solution of hypochlorite under heating between the washing and rinsing processes. Of salts of calcuim and salts of sodium, sodium hypochlorite is easy to use for practial purposes. The concentration of the solution of hydrochlorite is such that the effective chlorine concentration of the solution is about 100 to 1000ppm. The solution of hypochlorite is held at temperature e.g. above 70 deg.C and below 100 deg.C, preferably more than about 80 deg.C and the tablewave are exposed to this temperature for e.g. five to thirty minutes. Thus microorganism remaining on the tablewave, especiallky spores, are killed and removed very easily so that food posioning can be prevented. |
