A method of making an insulating glass (IG) window unit is provided. The IG window unit includes at least two spaced apart substrates that are separated from one another by at least one seal and/or spacer, wherein a first one of the substrates supports a hydrophilic coating (e.g., silicon oxide) on the surface facing the building exterior and either of the substrates supports a solar management coating (e.g., a low-emissivity coating) for blocking infrared radiation.
