Can I use this 99% Ethanol to clean VCR and video heads?

Yeah. They're a trap for tape gunk.
I rotate the drum counter clockwise with a Q-tip pressed on them. Counterclock seems to remove it better cause it was set in place with the drum turning clockwise.

Also look for a streak of tape oxide just ahead and behind the actual heads. Be very careful cleaning in this area.
