How Do I remove linoleum glue off tile flooring?

I live in apartment and the last tenant placed linoleum flooring over ceramic tile flooring in the batroom. What can I do to remove this "glue". I have already tried glue-be-gone and a scraper but nothing came off.

1. I've used a product called "goo-gone" but usually for small jobs. I found a website that states this: Hello, and thank you for contacting The Grout Dye Company in NY. You will need to use a solvent, such as a paint stripper, there are many on the market, I would recommend something strong like Rock Miracle, this product contains Methelyle Chloride, the highest level allowed by the EPA, read the instructions carefully and wear safety equipment. You can try a less volatile stripper like Zip Strip first if you prefer. Good luck. Another website indicated that if the linoleum was very old, it or the glue may have contained asbestos. They recommend having some of it tested. I can't imagine why someone would put linoleum or ceramic tile. Good luck.
2. well i found that wd-40 works pretty good. i redid my kitchen awhile back with peel and stick tiles. some were stuck together and left some glue on the top of some and i tried everything like acetone, mineral spirits, and others but i found that wd-40 worked the best but it will take some scrubbing with a brush
