We were cleaning our house. We were throwing out bottles of cleaners and the bag must leaked and we didn't know. It sat there for several days and it looks like whatever it was it bleached a bit of our floorboards. Is there a way to get this stain or bleach mark out?

Looks like laminate flooring, if so there is no way to "fix" it.
You would need to remove the flooring up to that point and replace with new.
