Just brought home a new MM Stingray. Looking fwd to posting some pics, but first things first. I took off the clear pickguard protector sticker and it left a sticky residue over the whole thing. I tried a liitle Simple Green (diluted) on a cloth and rubbed a small section - didn't help. I'm thinking a scotch brite pad but don't want to scratch the guard, so I figured I'd check in here first. Any ideas?
