  We describe our custom processing of the entire Wide-field Infrared Survey
Explorer (WISE) 12 micron imaging data set, and present a high-resolution,
full-sky map of diffuse Galactic dust emission that is free of compact sources
and other contaminating artifacts. The principal distinctions between our
resulting co-added images and the WISE Atlas stacks are our removal of compact
sources, including their associated electronic and optical artifacts, and our
preservation of spatial modes larger than 1.5 degrees. We provide access to the
resulting full-sky map via a set of 430 12.5 degree by 12.5 degree mosaics.
These stacks have been smoothed to 15" resolution and are accompanied by
corresponding coverage maps, artifact images, and bit-masks for point sources,
resolved compact sources, and other defects. When combined appropriately with
other mid-infrared and far-infrared data sets, we expect our WISE 12 micron
co-adds to form the basis for a full-sky dust extinction map with angular
resolution several times better than Schlegel et al. (1998).
