Long time lurker first time poster.I am very very new to wood working. I bought a used rigid 3660. It had some rust on it. I removed cast iron wings and got most of the rust off. However there is some black splotches left. How can I get these off and if I can’t will it affect performance any. Thanks, looking forward to asking a million questions. Sorry no pics can’t figure out how to load from iPad.

The splotches shouldn’t effect performance any as long as they’re sub-surface. You might be able to get them off by working at the surface with some sandpaper and WD-40, but you need to do a large area around them to avoid creating a divot. I’d start somewhere in the 100-150 grit range and work up to whatever level of shine you want to see….it’ll take some effort.

Maybe someone has a chemical suggestion that’s less work….

I use naval jelly with steel wool for rust removal. I then clean with mineral spirits and apply a coat of Johnson’s paste wax.

I got my TS after it spent 3 days under water, so it was worse than yours. Naval jelly or almost any decent rust remover and scotchbrite pads will work. All advice above is legit as well. There are many way to skin the cat.

I use fluid film to keep rust away. Its a little easier than wax, but either works just fine. What I like about the fluid film, if I leave a piece of “not so dry” lumber laying on the top, a quick spray and it will remove the surface rust. (I work with green lumber on occasion)

Don W,

What exactly is fluid film and where do you buy it?

here’s a portion of a unisaw restoration video series that deals with cleaning the CI top:

moving to progressively finer wet paper grits will result in greater smoothness and finish. here’s my uisaw top before and after:

naval jelly and a long sanding block for finishing,I use mothers on my top, but then I use polish also and rough grit to start then a fine grit to smooth out the rough grit does that make sense, anyway my rust problems have stopped but I keep my saws planer jointer all covered with a blue type tarp all the time they only cost 10.00 or so and save you alot of headaches down the road fighting rust, but my shop is a metal building with no heat so I spend alot of time oiling and polishing but not like I use to, I remember when I got my first tablesaw I put it together and took all the cosmo off and left it a couple days well it rained every day come back out and it looked bad it took a whole 3 hrs to get the rust off it was brand new so I learned my lesson keep them covered.
