After being off for a few months, I turned on our IGT 4th of July slot machine. I opened the machine to empty the coins and immediately saw this orange goo accumulated on the right hand side, over the electrical (I think) box. It had dripped down from above, near the arm area. Pictures are attached below. The first picture is looking directly inside the machine and the second was taken looking up from the drip. I have no idea what this is or how to clean it up and fix the machine. The service light is also flashing on the top of the machine. As you can probably tell, I am a novice (old lady, but still a novice). Any advice would be greatly appreciated.
