There is always more to show about doing windows. Here we see the inner half of the sash as it came out, with part of it already cleaned up. To clean the sash I spray it with Goo-Gone after which I remove the crud by sanding with steel wool #0000. Hard to remove dirt gets sanded off with a sanding block after which I use the steel wool to get rid of the scratches left behind from the sanding. After all is clean I use the steel wool to brush in the direction of the old brush-marks to bring back the original brushed look.
