Toluene is for Hypalon, not PVC.
Alcohol wipes might work on the glue, probably not the logo.
If that doesn't work you could try MEK, sparingly. Just know that the more MEK you use the more boat material you are taking off.
Is the glue residual from an old patch/handle/etc? If so mechanical removal may be the only way to get it off, and that is harder on the boat than cleaning it with MEK.
Don't forget gloves and respiratory protection. That stuff is nasty.
