I have an old friend who is starting down the woodworking path. He called me stating that his tablesaw was producing severely burnt looking cuts. Wanted to know if I could help tune up his saw. Knowing that I would get free run of his homebrew, this was a no brainer.

Conclusion, the saw is fine. The blade was simply covered in gum and pith. So, quick lesson to any beginners, cleaning your saw blades helps to lengthen their life and makes for nicer finished cuts.

Wow, you really had to earn that brew, huh?

Thanks for the tip!

I had a fellow who makes/sells table saw blades tell me years ago that nothing sells new blades like pitch buildup on otherwise perfectly good blades.
It seems that most people know that a clean blade cuts better yet we constantly hear of people being surprised about how well cleaning blades works. Maybe this is one of those things that just never really makes sense, yet there it is.

Clean blades cut better and last longer. A dirty blade cuts like a dull blade, and ensures that it will become one way too soon!

Thanks for the tip. I was thinking, for $100 blade, mine had gotten dull pretty quick. I’ll spend some cleanup time before my next project.

To clean a blade you can use a commercial blade cleaner or goof off (works good) and I’ve read a post that suggested wash soda (I haven’t tried it yet)

Oven cleaner is supposed to work good too.

Kaaboom bathroom cleaner is amazing effective along with a stiff bristle tooth brush. Its also cheaper and not as caustic as oven cleaner. It will however take off some of the teflon coating on certain blades. I have found that my Forrest blades get slight discoloration on the metal but none of this effects the performance. Lay your blade on a nonpourous surface, melamine, spray then flip and spray again. Let it set for about 30 seconds and scrub away the gum. Rinse with water and towel dry. Cut out a set of cabinets and repeat.

Greetings all,

You can also use Formula 409, Simple Green, any pitch and gum remover from any of the woodworking supply stores, but just go to WalMart and pick up the above mentioned items, and you’re good to clean…uur,go…...... I use the stuff from Rockler… I foget the name, but it sure works good….....

I found that for a 10” blade turn a 5 gal. bucket upside down the blade fits perfect spray with oven cleaner and let set spray off with garden hose no scrubing and no getting dirty wipe dry and reinstall it takes me about 10 min. best way i found.

good luck

Some of these higher-end blades are coated with a special anti-friction finish. Won’t the oven cleaner take it off and degrade the blade?
