self stick tile removal from hardwood floor

chickdiy

I know this has been asked before but I'm kind of looking for specific answer. What is the best adhesive remover that won't damage the original hardwood floor? The previous owners stuck the tiles right to the hardwood. I can get the tiles off with the iron/damp towel trick but what is the best product to use to salvage the hardwood underneath without having to sand? Thanks for any advice.

test a small spot somewhere that isnt noticeable
with denatured alcohol or mineral spirits
