Rewrite on them with dry erase and then clean like you have been.
We have some older dry erase books and boards that got packed away in a hurry and put in storage. In my haste I forgot to make sure they were all cleaned off. I am now finally getting a chance to pull them all out of storage now that my youngest is ready for them. Some of them are coming clean with a little elbow grease and the spray on white board cleaner. Others are not.
I don't want to have to throw out this many books but if I can't get them clean they aren't very useful to use. Some of them are so badly scribbled on.
Does anyone have any tricks to try to get the more stubborn ones clean?
Some have markers and some have dry erase crayons.
Thanks!

You can refinish them with whiteboard spray paint. It's cheap. At this time of the year, it is often in sale because teachers are pretty desperate to make their classrooms sparkle, but most of us won't be paid until after the first week of school.

I've used a few different tricks off of the above link. WD-40 has worked well for us.
I just used Windex and that seems to do the trick just fine.
If you go over the old markings again with a dry erase marker, they will come right off when you wipe them. I don't know why it works, but it totally does.
Rubbing Alcohol
Other cleaners will leave a residue on it, thereby making it not effective and affecting the surface of the board.
Try pinterest. I remember seeing a way to clean dry erase boards on there. Unfortunately I don't remember what it said. They suggest everything from rubbing alcohol to magic erasers :)
