My husband and I put down some vinyl flooring in a very old home where the floors were very uneven which made it difficult to get the vinyl tiles matched up. We used a colored caulk to fill the spaces. To clean up the excess caulk we used goo b gone. The caulk in the tiles needed 3 hrs to dry, so we never cleaned up the oily residue. My sister was going to do that later last night. However, she was unable to get the tacky, oily residue up. She took a rather hard fall this a.m. We returned to her house with Goof Off but it didn't help. We tried: hydrogen peroxide, liquid detergent with bleach, and rubbing alcohol with little or no change. I was able to scrape off some excess caulk but it's the oily reside that's the problem. Please give me a clue as to what I can use to restore the vinyl tile to safety while walking on it. It's the peel and stick type. I've used it in an old house next door and had no problems. I did remove all the old flooring before placing down the tile pieces. I need some quick help or answers as she is alone and on a fixed income. She really needs some help.
