Yesterday I decided to wipe some sticky stuff off my expensive old Freud carbide tablesaw blade and used acetone, just a little on a paper towel. I thought it looked different and then realized the name Freud and the blade number were gone. Guess I chose the wrong solvent!!!!

a rose by any other name is still a rose...

any reason you are bent out of shape just because some lettering is gone?

same thing happens when you take a blade in to be sharpened (assuming the shop is properly cleaning the blade first)

The blade NUMBER is gone.

I'm too lazy to go out and check my blades, but from memory Freud has 2 numbers on a blade...the serial # and the model #...not sure if there is any real use for the serial ("old Freud carbide tablesaw blade") and I would think the model number should be fairly easy to look up at their site, assuming it is still in production...

just trying to say: take a deep breath, relax, and realize it's not really an issue to be worried about...

if the blade number was some sort of marker the owner put on it, then at least they are aware of what happened and can write it back on...I DO NOT suggest etching it in with a tool as that can warp the plate (think of how one brings a square back into true square)

Freud makes a user friendly/safe blade cleaner. Spray some on, let it sit for a few minutes, and a scrub with an old tooth brush.
I then wash with hot water, wipe with a clean rag, and you're good to go. Lots of people think their blades are dull, when they are just dirty, and need to have built-up resins cleaned off. I used to use Spray 409, but I haven't seen it around here for a long time. It worked just as well, and was great for cleaning the grips of my golf clubs!

I used the spays a few times, most of it is lye based. Does a good job but will also clean off the label. Switched to using good old household ammonia. Put about 1/4 inch water in the sink add a couple splashes of ammonia, let it sit about 5 minutes then scrub with a tooth brush. Rinse with water and dry with a paper towel. I like to spin it up on the table saw for a final drying.

I wasn't really bent out of shape, just surprised, and a little amused. You would think that it would have been permanent, but oh well. I have to say though that I have never had a blade come back from the sharpener with the name gone. The only concern I have is if I decide to sell it. Next time I will try 409. I only used acetone because that's what I clean my router bits with.

apparently Simple Green is doing a good job cleaning blades...Freud makes specific mention of the fact that some spray on cleaners react with the brazing of the teeth...
