Can hot coals be extinguished by dousing them with water?
Weber does not recommend this practice, as you risk damage to the porcelain finish of the charcoal bowl. Hot coals can be extinguished by closing all the dampers and allowing the cooker to sit overnight. If you need to extinguish the coals quickly, dump them out of the cooker and then apply water, or dispose of hot coals in a dedicated metal ash bin. Rememberashes that seem to be cold can actually be hot inside, so take care when handling ashes at any time.
