What is the best product( stripper) on the market to remove balck tar( adhensive) from solid wood floor? Home built in 1920's. Help!

How much tar are you talking about? A small spot or a large area?

We had some tar from linoleum floors on our hardwood floors. My wife used a scraper (like a wallpaper scraper) along with an adhesive remover from Home Depot (can't remember exact name, sorry). It came off pretty easily. Then I sanded the floors and everything else came up. Stained and poly the floors and they're like new. If I can find the old can, or remember the name of the adhesive remover, I will repost here with that info.
