Do you have an old table saw that has had rust on it? Have no fear because there are great options for removing table saw rust. The first step in every situation is having the right assessment. If you have only lighter and superficial rust, you don’t really have a big problem in cleaning it up. However, if the rust has accumulated for a couple of years and would seem pretty deep and substantial, then the table of the saw would likely be too damaged to return it to its original state. With that said, the saw is should be pretty usable – although it wouldn’t cut as smoothly on a surface as it was when you first bought it.
First of all, you have to resist the urge to attack the saw table with a sandpaper. Instead, go for an alternate kitchen scrubbing pad like a Scotchbrite, just be sure it’s not steel wool and you use some mineral oil to act as a lubricant. You need to use enough Rust Inhibitor mineral oil to make the job easy but you don’t need to have a lot of excess so you won’t need a lot of effort to wipe it off after you’ve done the scrubbing.
If you don’t have some mineral oil, you can also use a WD-40 in removing table saw rust too. Although the WD – 40 works the same way, you might need to apply it a few times because it evaporates faster as compared to mineral oil. Also, if you’re using the WD-40, remember to apply it frequently and even lubricate the entire table saw until you’re finished scrubbing.
Another great idea if you have seriously rusted cast iron table is to apply naval jelly on it. You need to be careful in strictly following the instructions on applying naval jelly to the latter, especially when you’re removing it so you’ll prevent pitting the cast iron. Naval jelly has a pretty aggressive rust removal action so, you really must get it off the surface properly to stop the cleaning process.
Once you’ve removed the rust, you need to take additional measures that the rust won’t return. There are a lot of commercial products that promise to not only protect your table from rusting, but also lubricate it to make your stock slide easily when you’re cutting. Among these products are the T -9 and the Slipit which are easily found among woodworking supplies and online stores.
If you’re looking for another age-old solution, you might want to try out an old wives’ tale by applying distilled vinegar in removing table saw rust. It is said that it’s a rust inhibitor so, once the rust is removed by either of the methods, you should wipe the entire table down with liberal amounts of the vinegar. Allow the surface to completely dry before you apply the final protectant or lubricant. The acidity of the vinegar is believed to keep your surface clean and to remove the final bits of rust which you might have overlooked, as well as prevent the future buildup of more rust.
