How do you retain the learnings? I have a black board for the same purpose but am not able to commit to it due to this reason.

Yes, that's a downfall. I bought a large sheet of whiteboard material for about $12 and cut it into quarters. If I have some subject that's really important, I'll leave that one stay for a while.

I probably should transfer the really good findings to a notebook, or maybe take a photo. But I haven't yet.
