I have a Garmin 3210 on my CC and last season I purchased one of those plastic screen savers for it.... well corner was peeling just a bit so decided it was time to change it. Unfortunatly it seems like its leaving a glue like substance on the screen as i start to peel it off... dont want to use a razor blade to clean it off... anyone have this problem before or can anyone suggest a cleaner to use on the screen to remove this substance

Thanx in advance......
