Before you do any more washing, eyeball the front of the tuner for an access hole to the tuner's oscillator adjustment (sometimes called the 'bulls eye' adjustment). Each of the channel strips contains a metal slug which aligns with the hole when clicked to the corresponding channel (eg., when you click to Ch.3, the Ch.3 slug will align with the hole), and you adjust the slug with a non-metalic thin screwdriver to tune in the channel. Do this with the fine tuning at mid range. (Or if the VCR uses Ch.4, do the same with the tuner clicked to Ch.4).
Occasionally one or more of the slugs will be missing due to someone's screwing them all the way out. You should be able to shine a light through the access hole to verify each slug as present, or pop each of the strips outa the turret to visually inspect them and see if any slugs are missing.
Don't worry about the vertical issue until you get the signal tuned in properly.

Sadly this didn't do the trick. Adjusting this tuning slug gave me much the same results that adjusting the ft gave me, except on a much bigger scale. Again the "bottom" picture went from sharp to soft to just static on each direction of the rotation, but all the while seemed to be beneath another picture. The "top" picture had no change at all with either the tuner slug, or the fine tuning adjustment. I will try to take video tomorrow while adjusting ft and the tuning slug to show on video what I am describing.
