I bet "Goof-Off" would have made the job a lot easier (although it might have left some residue that would need further attention)... or a giant roll of masking tape with the sticky side out for "dabbing" it up....some unlucky production assistant was handed a putty knife to scrape all the residue from this "clean removing petroleum-based adhesive" tape off the studio floor so that it could be buffed in advance of some VIP visitor. It was a nasty and all day job...
