How to Deal With Ink/Marker on Manuals?

[Shokwav]

I recently bought a copy of Son Son II for $20 off eBay. There's some pen markings on the back of the manual, but luckily it's only on the white portion of the manual (pic). Is there any way I could remove the pen markings without causing corrosion/water damage to the manual?

It's neatly written, so I would leave it.

It adds character and shows that the game was loved by a previous owner. I'd leave it.

Huh, never thought about just leaving it xD alright.

All things considered, that page of the manual looks nice.

I don't get it?

I have games that previous owners loved so much it looks like they took a bath with them, used them for a coaster or folded them up to carry about in their back pocket.
I bet they were heart-broken when they sold the games on. ;)
