Ever try and remove a label from plastic? Yep, WD-40, Goo Gone, and others including yep peanut butter well just don't really work, or damage the plastic that the label is attached to. Most of you have used the old stand by a hair drier as well. But that tends to leave a residue, and you cant use it on PCB boards as its way too hot.
Well, you got to check this stuff out. Motsenbocker's LIFT OFF Tape, Label, and Adhesive Remover. I have this old Milwaukee too case that had some fool put masking tape on. And I could never get it cleaned up. Squirted a little on the mess and bingo it came off with a scratcher sponge. A little soap and warm water and it looked factory fresh.
On-line it is about $10, but at Walmart, it is about $6.
Sorry Fix: not masking tape but Duck Tap!
