Still 3M adhesive remover, or denatured alcohol?

Last time I did this the lower face label came off nicely, but the mirror flap was a freaking mess.

Anyone had fail safe method work well on either side?

Thanks.

 

If its just the adhesive, you might try blotting it with a little mineral spirits on a soft cloth. While a little greasy, it is relatively safe on most surfaces, just needs to be cleaned off afterward with some natural citrus degreaser. Do a little tester on the parent material around the edge first just to make sure though
