A wildfire defense spraying system installed on property with combustible property surfaces, and adapted for spraying the combustible property surfaces with an environmentally-clean water-based liquid fire inhibitor for defending against wildfire by inhibiting fire ignition and flame spread caused by hot flying wildfire embers created during a wildfire storm. The wildfire defense spraying system includes: a storage tank containing a supply of environmentally-clean liquid fire inhibitor comprising an alkali metal salt of a nonpolymeric carboxylic acid, and triethyl citrate (TEC) dissolved in water according to a prespecified formulation, wherein the environmentally-clean water-based liquid fire inhibitor remains stable without the formation of solids at expected operating temperatures, and ready for immediate spraying on combustible surfaces. An electric-powered hydraulic pump system is connected to a remote power control switch employed to supply electrical power to the electric-powered hydraulic pump system. A plurality of spray heads are mounted about the property and any buildings thereon, and arranged in fluid communication with the storage tank and the hydraulic pump system. During operation, the hydraulic pump system automatically pumps environmentally-clean water-based liquid fire inhibitor from the storage tank and through the spray heads to generate a spray pattern of environmentally-clean water-based liquid fire inhibitor over all the combustible surfaces on the property. As water molecules in the sprayed environmentally-clean water-based liquid fire inhibitor evaporate to the environment, thin fire-inhibiting alkali metal salt crystalline coatings form on the combustible property surfaces, inhibiting fire ignition and flame spread in the presence of wildfire embers.
