PCB I'm looking at is been submerged in this "yellowish" gel , to make it waterproof. I have managed to remove most of it, mechanically, but I do wonder if there are any more efficient ways to get rid of it. The whole PCB is still in a plastic tray -and if I want to remove it entirely and see the underside of it - I will have to use other means than mechanical. I do not want to destroy it, pretty much trying to hack a device and adopt it for my own needs.
It's a robotic lawnmower.
