However, when washing with acid, hydrogen gas is generated due to a phenomenon called so-called acid shock, that is, the action of acid on metal. When the hydrogen gas permeates from the base metal toward the glass, the glass lining layer may be damaged. However, if the acid concentration is 10 wt% or less as described above, 60 ° C
If the cleaning is performed under the condition of 30 minutes or less, generation of such hydrogen gas is prevented, and damage to the glass lining layer is prevented.
