The lighter fluid did not work - it evaporated too fast.
I did not have this citrus thing and I have decided to try the CA debonder.
CA debonder worked but I had to be patient. It took 25 seconds for one drop of debonder to weaken the adhesive to allow me to start peeling the remainder of the foam pad with my nails.
It took two minutes and one additional drop of debonder, to peel the entire remainder of the foam pad.
The lead and its foam pad have been removed without damage to the Microlite covering.
I have cleaned the area with alcohol and it looks fine.
Happy Flying,
