A cast iron table saw develops rust over time, damaging your saw. Clean rust off of your table saw with the help of a woodworking professional in this free video.
Hi, I'm Dave Trull with The Trull Gallery, and I'm going to talk to you today about the best way to remove rust from your table saw table. This is something you've got to keep an eye on if you have a cast iron table. Some of the lightweight tables that are out now have aluminum tops and it's not an issue but the larger heavier cast iron tables are very susceptible to rust, and it's actually a very easy process to clean it off. Depending on how bad the rust is there's a couple of different processes you can go through. If it's really heavy you can start with something like a random orbit sander and a medium grip paper, sand it down and work your way up to the finer papers up to about 220 grit and then you can switch over. If it's a small spot or a minor spot you can start with some wet dry paper, 220, 400, in that area work your way up or if it's just something that has just gotten a little moisture in it, it's been damp and you're starting to get some surface rust, you haven't used your saw for a while, you can just get away with a simple abrasive pad. It also helps to use on the higher grits when you get to the wet dry papers and the abrasive pad to use a little light oil. I use something as simple as WD40, a light spray helps you work your way through and the important thing is once you get the rust removed is to make sure you wipe all that oil off because you don't want that oil to transfer to your stock next time you make a cut. It may take a few minutes or a few hours depending on how bad the condition of your top is in but once you get it cleaned up, take care of it from that point forward. It's just something you will have to do touch ups from that point on. Okay, and that's how to clean the rust off your table saw top.
