Handsaw woes

There's some kind of coating on my handsaw blades. All of my saws have it.

With use, it's slowly starting to wear away, but I want to remove it completely. I constantly have to use 3-in-1 oil to lube the saw just so it doesn't bind and track poorly.

Any suggestions on what to use to remove the coating?

Think I've heard mineral spirits or denatured alcohol recommended to remove it. I've removed it with one of those before, but can't remember which I used sorry.

If you do remove it just make sure to keep them oiled as they'll become super prone to rust issues.

It's kind of strange that this line was delivered in that movie of all things. It's still a really good quote, and certainly a dang good thing to remember.

Acetone will strip it quick.


acetone also attacks plastics - use care not to slop it around / lay the rags places you don't want stripped, etc.

I keep meaning to come back to this thread...

Acetone did the trick, but it wasn't a pretty process. As best I can describe it, acetone "melts" the coating rather than dissolving it. You're not going to be able to just wipe on/wipe off - it takes some effort. Start at the back of the saw with a soaked paper towel and wipe towards the front of the blade. Flip the towel over, throw away and repeat. If you use a circular motion, you're just creating more work for yourself.

I threw my used rags in the fire pit and burned them immediately. Not sure if acetone has combustion issues like linseed oil, but decided to err on the side of caution and not throw them in the regular trash.

technically acetone would have a spontaneous combustion issue - however practically it does not.
it is the fastest evaporating (common) solvent.

left on a open rag, it's gone in 4-5 minutes. nice - however only nice in lots of open air.

all of the solvents need to be respected and properly handled / disposed.

some are more prone to issues,some less. regardless, testing the theories is not recommended....
