Adhesive removal

[Rob Grady]

Good morning. I have a good customer who used adhesive backed plastic covering on his steps during construction. It was left on for about a year. He sent me this photo asking if I could remove the residue.
I am thinking to mist CitrusSolve, a wallpaper steamer to heat the affected areas really well and extract with my TM .
Have any of you ever ran into this type of problem? Thanks for your input!
