I have managed to get a quite a bit of rust and glue stains on my cast iron table saw top. I searched LJ for rust removal topics and followed the procedures but haven’t been able to get rid of them. Sanding it removes it somewhat and also leaves scratches. I think the rust and glue is deeply entrenched in the pores of cast iron and needs some chemical agent to remove it.

Would CLR work well for this? Have you tried it and had good/bad experience with it? I do have Boeshield T-9 but I think that only provides rust protection but not removal.

Wet sand with 400 and 600 wet-or-dry sandpaper and a solvent such as WD 40 or kerosene. Dry it, wax it, and forget about stains. You’ll enjoy a super smooth top better than a show piece.

From personal experience, I get the best surface using WD40 with a 3M scourer. I minimised the elbow effort involved by backing the scouring pad on to a large orbital sander. Don’t worry about the stains, but as Bill White says “Dry it, wax it, and forget about stains”

I use a Scotch Brite pad rubbing compound and a random orbital sander. This removes almost any thing. then I use paper towels to clean off the rubbing compound. after that I apply floor wax and buff with a pad and random orbital sander. This last for months and makes your wood fly through your table saw.

I use PB Blaster, and keep a set of progressive grit worn out sandpaper, spray and work my way through the grits when I get to 220, I then use a spray cleanser and paper towells to cleanse the surface. After that a couple of coats of wax and she is good to go.

No need to worry about scratches it is a tool!

Thanks guys. My number one concern was trapped rust leading to more rusting. Sounds like it’s not going to be such a serious issue. I will try to do the best possible cleanup and get the top to a clean and smooth state.

I transported my Delta 40-601 Scroll Saw yesterday and got caught in a thunder storm. When I unloaded it today, the table was covered in surface rust. I just happened to have a half used gallon of concrete rust remover. Poured a little on to a scotch bright pad and the rust evaporated within 60 seconds and left a mild foam. Wiped it off with a paper towel, then followed up with a wet one. Went back into the house to get a dry towel to wipe it off and the rust had started to grow again. Re-did everything quickly and applied a coat of paste wax and now have a Bright and shinny table.
If you have a rust pitted table or bed, I would consider doing the same thing, thus removing all rust. But in reality, like they said above, get the surface rust off and after you applied wax, your machine would work just as well.

Have your say...
