If you do a lot of ripping of resinous woods such as Yellow Pine as I do (I used it for my deck on Toad Hall) you will soon build up a thick yellow pitch layer on your saw blade. The drag it creates makes ripping an even more tedious job than it is already.

In any woodworker's catalogue you can find many high-priced products which purport to remove this pitch. You spray 'em on and wipe 'em off! In your own kitchen however you probably already have a product which is just as good; it's Easy Off™ Oven Cleaner!

You use it just as you would the high-priced sprays. Spray it on, let it sit for about 15 minutes and wipe it off. For really thick build-ups I find its easiest to wipe it off with a little steel wool, and sometimes it takes two applications, but no matter how thick the pitch is on the blade, a generous application of Easy Off™ (or similar) and a little patience in waiting for it to work will result in a sparklingly clean
blade.

(Note that if there are any painted identifiers on the blade they will be gone to!)
