I also have white leather and 3 kids. We finally got black for the living room, but have moved the white into other rooms. For ink
finger nail polish remover will take the ink off. But when you are done I would put some lotion or some kind of moisturizer on it, it may dry out the leather.
Also I found for different stains, like candle wax I had once, that
degreaser works well on alot of things that other cleaners wont get. I use Zepps formula 505 from Home Depot, very cheap.
For crayons and gum and other sticky stuff,
Goo Gone works wonders. Found almost anywhere to buy.
Hope this helps, I know that white leather can be a pain, but at least we can wipe it clean, unlike fabric couches.
