image of the part to clean up after cleaning the area with alcohol, let dry completely.I did not completely remove the entire top of the coil just outside edges. I could not stay the whole coil complex. The medium was still covered. Remember, it was a last ditch effort for me to pay my phone, and if that does not work, I throw it away. So try all other methods before trying it ... Oh, and you can try scrubbing the coil without removing the lid of it, but it did not work for me.
