Re: Happy surprise but what to do now
There are few adhesives that can be removed without the use of solvents of some sort. If you are certain that these were peel-n-stick tiles, then I'd start by seeing what the manufacturers of these tiles recommend to clean up errant sticky spots. This should be as easy as reading a few product labels or perusing the manufacturer's website.
The next thing to do is to test your chosen removal method in a small, inconspicuous spot to be certain that the cleaning procedure will work and that it will work without damaging the wood. If you use a solvent, make sure that solvent isn't going to affect the color or the ability to refinish the floor, this usually rules out petroleum based cleaners.
You can also consult with a few reputable flooring repair/refinishing contractors for methods that won't damage the wood.
