what can I use to clean the back of my phone that has glue from a case I used?

[iMore Question]

I bought a phone case and I let the seller put my phone in the case. I learned that the case was to small for my phone. The seller removed the inner case and put my phone in the case that had glue on the right side that held my phone in place. I discovered that the case was not large enough for my phone, so they removed the rubber case to make my phone fit. It was a fold case that would hold your cards also. Its called a diary case. Thank you.

I would try rubbing alcohol. Probably the safest thing you can use.
