The table saw is a must-have power tool in any do-it-yourselfer's garage or workshop. To ensure your table saw lasts for years and operates at optimal safety, you must take care of it. One of the most common problems is table saw rust. Even when these tools are stored undercover, humidity and other factors can cause table saw rust spots to form. If you do not immediately address the rust problem, you may risk your safety during the table saw's operation.
The main safety issue with table saw rust is when it causes lumber to snag. You want your wood to slide smoothly across the top, not stop and shudder on the table saw rust. If the lumber is rough or has knotholes, these things can snag on the table saw rust and possibly kick back the wood, possibly causing injury. It may also damage the saw blade. Knowing how to remove table saw rust is an important part of this power tool's maintenance.
Minor Table Saw Rust Spots
Minor or superficial table saw rust is rather easy to remedy. You definitely do not want to break out the sandpaper or steel wool. Instead, use a kitchen sponge with a rough scrubber on one side. Spray the table saw rust with WD-40 or apply some mineral oil with a rag. Next, scrub the table saw rust with the rough green scrubber side of the sponge. If you use WD-40 to remove table saw rust, you will need to re-apply every few minutes, as it tends to evaporate quickly.
Heavier Table Saw Rust Spots
To remove table saw rust that is heavier, medium grit sandpaper and the WD-40 or mineral oil is required. These heavier table saw rust spots need a little extra effort for proper removal. A handheld sander or even an orbital sander can make the job of removing table saw rust a little easier. As with the procedure for the minor spots, you will need to apply the WD-40 or mineral oil to the table saw rust spots before sanding.
After removing the table saw rust, wipe down the top with a cloth moistened with vinegar. The vinegar eats away any minute table saw rust spots and also inhibits future table saw rust growth. Apply a paste wax to the table saw top. The wax forms a protective barrier to prevent moisture from collecting on the top and creating more table saw rust. As a preventative maintenance measure, you should apply a coat of wax monthly. The side benefit of removing table saw rust and applying the wax is that your wood will glide more smoothly across the top, thus reducing the possibility of injury from kickbacks.
