Carpet underlayment

We used a heat gun and scrapper. It was the only thing we could find that would work. Just don't over heat and burn the wood.

Heat will make it like glue! Scrub something with a rubber base, like shoes, over the floor. It will roll up and can be vacuumed or swept up. Then clean floor.

I agree with Lokie. I also used a heat gun and scraped. Keep the heat moving just to soften the adhesive and gently scraped. I did round off the ends of the scraper so not to dig into the wood. Then I use Goo Gone to remove the residue. Washed the floor down with lemon scented ammonia.

We used a scraper, nothing else seemed to work
