Might not have been the same glue, but we had a similar tile under square linoleum type tiles. I used a green scrubby, clorox clean-up and very hot water with occasional abbrsive cleanser. We were told there is an adhesive remover at home depot but this worked fine with lots of scrubbing. Also, let the hot water puddle and soak for 10-15 min on an area first to soften the glue. After trying to repair the original floor, we ended up removing it and replacing with a similar new tile because of a big spread crack and slope at the toilet end of the room. Hopefully yours is a keeper! Here is a link that might be useful: album of bathroom renovation

My inclination is to say no you can't get it off.I would use some type of adhesive remover perhaps..but I believe the efforts will be fruitless. Good Luck. Maybe a citrus styled remover as the fumes will be limited!

I wouldn't dream of using gasoline! I'm worried enough about the fumes from adhesive remover -- which is why I was looking for something milder that could still do the job... I wonder why bleach would work, that makes no sense. I found out the hard way that cat urine would remove old adhesive -- when we removed the original linoleum from our 1941 kitchen, our elderly feline was quite upset by the construction and started using the exposed subfloor instead of the litter box. Every spot she went, the remaining old adhesive came up easily. However, there are distinct disadvantages to that method!!! Hmm, maybe I should try cleaning ammonia? but, again, fumes...

I had some glue on a shower. I used a steamer to soften glue to remove it.
