Greasy marks

I need a bit of help. Over Christmas we had the table tennis up in the garage and it was left there for a while, my parents have been putting things on it like bowls and it has loads of greasy marks on it now. I think they have tried a grease remover or something but whatever they tried hasnt worked.. Does anyone know anything that might work?

It's an outdoor table and we normally have it up till the winter so maybe the marks will fade away but i dunno
