How do I remove glue from wood trim?


We pulled up the carpet and the nail strips. I think the nail strips were glued down and I haven’t been able to get that strip mark by the trim off the floor. My husband doesn’t want to redo the hardwood floors so my only option is to try to get the glue/marks off the hard wood. I read to try WD40 and that didnt work. We are going to paint the trim so I’m not worried abt the different colored part on that. Please help! I try to be a DIY but am not very handy!

q how do i remove this glue from around the trim is it glue
