Cleaning cosmoline from cast iron table saw

So I got a new Ridgid R4512 and trying to get the top all cleaned... I spent about 30 minutes scrubbing with paint thinner and a paper towel.. and it still looks like this.. the discolored spots are not sticky anymore, but as you can see.. it doesn't looks clean. What else can I do to get rid of this stuff?

Fine steel wool, rubbed in the direction of the machining. Those marks look a lot like rust.

Cosmoline is what rifles and pistols are coated with, in the military.
Mineral Spirits will take it off, but the easiest way is to use a propane torch.
It melts at very low temperatures (similar to candle wax ... around 140 degrees F). You can pass the flame of a propane torch over the surface fairly quickly, then follow immediately with a cloth rag.

I sure hope it's not rust.. I just pulled the plastic off today! It didn't look like rust, more like "smudges" where the plastic was wrinkled and the cosmoline was thicker.. is what I'm thinking it is.

I would just rub wax in to the top using a scotch brute pad and buff it off. It more important it is smooth slick and moisture resistance than look clean. Over time with many waxings it will look great.

I don't recommend steel wool as the tiny particles will imbed in the top, causing more rust. Use Scotchbrite, that is what is used for finishing stainless steel. Charcoal lighter will also work as will carb cleaner- just do it outside.
