After a day or two, it will etch the prefinish. I have heard good success with magic eraser. Test it first.

If nothing works, you will have to have it sanded down and recoated, which you will lose all manufacturers warranties on the finish. You know that 15 or 20 year warranty you purchased.

Just moved into our new home and discovered glue on hardwood throughout kitchen and tracked/dripped into the great room. Used Mirage Clean to remove it and it worked. First, sprayed the cleaner on an O'Cedar Microfiber Flip-Mop and mopped a small section. Then, got down on hands and knees and did each spot where the glue was. Sprayed some Mirage on a soft cloth (washcloth) and rubbed it on, gently, then scraped the glue off with my fingernail. Too concerned that anything more abrasive than my fingernail would take off the finish. Did the whole kitchen/dining/great room this way. At the end, I mopped the entire area again with Mirage Clean. This product I got from my flooring dealer; I plan to use it regularly for cleaning. No residue build-up. He also said Armstrong products are very good.

Took me 12 hours of hard labor, hands and knees, but worth it, as I now have a glue-free hardwood floor and I didn't damage the surface. Twas not a happy camper when I discovered this and I probably could have complained loudly and insisted the builder take care of this. But I wanted careful attention to it, not a quick clean-up.

As an award to self, I went out and found three counter stools on sale!

Thank you all you Garden Web members. You've helped me tremendously during the building process.

Magic Erasers and Pinesol to remove the haze left from my flooring guy's attempt to remove the glue.
