I have heard about many OrangeGlo nightmares on hardwood. Most of the time, the problem is that people are using OrangeGlo on hardwood that is finsihed with polyurethane. The OrangeGlo does not absorb into the surface, but sits on top creating an oily residue.
I have heard that some people are sucessful removing this with windex or a solution of vinegar and water. Don't get the floors too wet as they will take in moisture and swell over time.
