Flooring Question - removing vinyl tile GLUE from concrete?

[bayouchipette]

Today I had the bright idea to pull up some old linoleum from our half-bathroom. It was already there when we moved into this house 10 years ago. Well, lo and behold, underneath it is vinyl tile with patches of mold on it, so of course I want to remove the vinyl tile right away. Now comes the fun part - after scraping and scraping with a putty tool and pulling up the vinyl tile pieces, I now have that yellowish color glue still stuck to the concrete. I sprayed "Goo-Gone" on the floor and will try to get the glue off in the morning. Does anyone have any easier alternatives to get the glue off of the concrete floor? After doing this all day, I now feel like I have hands like Shrek and that I should be walking at a constant 90 degree angle. LOL. Any advice would be appreciated. Thanks!
