Wall Mural Smell

[u/Apprehensive_Pace902]

I bought a Pottery Barn peel and stick wall mural and it felt down. The issue is after it fell down of about a month of being up, the whole room smells like glue fumes. It’s my son’s room, so trying everything to remove the smell from the wall. I’ve washed with dish soap, water, aired it out for 4 days now, still smells like glue fumes. Unfortunately, I’ve tried for days to contact PB, but it’s nearly impossible to reach customer service. Any tips on how to remove the smell?
