On a quality stationary cutting tool, such as a table saw, radial arm saw or bandsaw, the table platform is very often made of cast iron, which is a durable surface that is very stable and vibration-free, but which can also be susceptible to rust. This will keep your table surface clean and slick, allowing workpieces to glide through the saw smoothly. Lower quality tools may have tables made from steel or even aluminum, and while protecting these surfaces is not going to prevent rust, there is still merit to keeping the table surfaces clean and slick.
So I’ll show you how I remove rust from my table saw and protect it from future damage in this post. So my table saw can quickly get some surface rust like you see here. That’s how to remove rust from a table saw.
Rob Johnstone: While there may be better ways to take care of the cast iron, when I recently moved my machines to a storage facility, I first slathered on a super thick layer of paste wax and just left it there. Chris Marshall: Warm and cold temperature swings aren’t really a big deal for stored machinery, provided the relative humidity remains low. “Hot and dry” or “Cold and dry” will keep rust at bay.
If you are cleaning a heavily rusted top with WD-40 and a Scotch Brite Pad, after you get all the rust off wipe the top down with mineral spirts and towel dry completely and then wax the surfaces. You will have to coat it several times with the wax of your coice it will finally get coated and stop rusting maybe, I use shellac,it gets into the pores of the casting very well, it’s kinda hard to get off or you just sand it smooth but it works great I put it on my jointer as an experiment, and it has worked great, it has not rusted one time, if I used wax I would have had to put many coats on the surface, try a small spot with shellac and a large spot with wax and see the difference, if you can put the shellac on thin and get the excess off quick you want have to sand as much same as building a finish on wood give it a try it you might like it I sure do. Wood magazine did a comparison on the best rust removal, rust prevention treatments, including Johnson wax.

What oil keeps tools from rusting?
Best Rust Prevention for Hand Tools That’s where boiled linseed oil can help. It forms a hard protective film when it dries, the perfect way to prevent rust and damage on hand tools. I coat the blades and wooden handles of all my outdoor hand tools with it at least once a season.
Will paste wax prevent rust?
One of the biggest reasons to use wax is to help prevent rust. Metal paste wax creates an additional barrier on your car to protect against daily wear and tear. The outside elements slowly deteriorate car paint over time. This means once the layers of paint peel away, the metal is exposed and develops rust.

How do you keep cast-iron hardware from rusting?
Heating the pan and allowing the oil (often flaxseed oil for cast iron pots) to coat and protect the cast iron helps prevent the cast iron from rusting by keeping water away from direct contact with the metal. It essentially forms a thin protective film over the iron’s pitted and porous surface.
