HOW TO PREP SAWBLADES
I know there are other ways to prep sawblades but this is the way I have found is the easiest for me.
I buy a scrubber that attaches to my drill made by Scotch-Brite, Paint & Rust Stripper Large Area. It looks like a giant Brillo Pad for your drill. I do suggest you wear safety glasses and wear gloves! Scrub sawblade down to the bare metal.
Once you get the rust and debris off the blade, wash in hot soapy water and rinse well with hot water. If it is warm outside, I will set the blade in the sun for a few hours to let the metal dry completely or I will turn on my oven to warm, or 200 degrees, and put the blades in there to dry completely.
When the saw is completely dry, spray with a rust preventive flat black or flat white paint. I prefer Rustoleum spray paint. Spray both sides and let dry overnight before putting on your design and painting.
