Why not to use oven cleaner to clean your Carbide saw blades. Safety Tip!

- In this video I discuss why you shouldn't use oven cleaner to clean your carbide tipped saw blades. A Bio-chemist friend of mine helped me out with the chemistry on this. Below is what he sent to me:
OVEN CLEANER:
Oven cleaner is primarily sodium hydroxide, which is a base (alkali), not an acid.
In the pH scale acids are closer to 1, bases closer to 14.
They have to be basic to most efficiently attack burnt on food-stuffs (carbonized matter).
Sodium Hydroxide (NaOH) reacts with tin (Sn) which is the biggest component in brazing compounds.
The brazing is what holds the carbide teeth to the steel blade. They can’t be welded. Carbide doesn’t weld.
Tin reacts with sodium hydroxide and water
Sn + NaOH + 2H2O → Na[Sn(OH)3] + H2
To form a new tin compound called Tin III hydroxide [Sn(OH)3]
This will pull the tin out of the brazing and release the teeth.
---------
SIMPLE GREEN Regular:
This is an acidic solution. (Not a base like before) but problems still arise.
Almost all metals react with acids.
And brazing compounds contain tin, cadmium, & silver, or a combination of two of those.
It’s all the same reaction for each metal in the brazing compound, but let’s look at tin again.
Sn+ 2H+ → Sn^2+ + H2
Once again a new tin(ion) Sn^2+ compound is formed, which pulls the tin out of the brazing and releases the carbide teeth.
Either way the reaction is indeed slow. This is why we don’t have dead people everywhere.
But just the same. It can be very dangerous.

Hi Michael, thanks for the heads up . I’ve just cleaned my oven , and so got to wondering if the same product could be used on my saw blades . So I thought I’d check out the science first . You speak a lot of sense and you put the brakes on me using oven cleaner, so many thanks for that . Somewhere in the back of my mind alarm bells rang out about sodium hydroxide reacting to certain metals , so I’m glad I checked . Kind regards John 😊😮👨🦳🪚🔨🙋♂️
lt is good of you to explain the dangers of using oven cleaners on tools.
John Augustson thank you.
Good advice Michael 👍
Smithson Creations Handcrafted Woodworking thank you
Thanks for sharing that valuable information! I'll be looking for the purple Simple Green product. Thank you for sharing!
Mama Bear's She Shed Tracy Keaton you are welcome
awesome tips for anyone with a saw. i belive 100% what king told you about oven cleaner, im just wondering has there been any tests done to prove that its the cleaner that caused the carbide to come off and not something else? or just we know the given chemicals in the cleaner do react with the elements in the blade so its just a assumption based on relative data?
Shaun Kennedy that’s an excellent question and one that I will have to get back to you on. I am sure that someone has actually tested it but I will have to research it and let you know.
I have looked. And I could not find any testing data.
I have seen forums where people are posting a link to a study done by Freud, but the link is a dead end.
All I have is the chemistry. But that’s enough to scare me away from using oven cleaner. (Especially when the real cleaner is almost the same price)
I’d love to see some legitimate lab testing.
I’d consider doing doing it. But I think you would have to test the force required to pull off a carbide tooth on a new blade. Probably lots of times to establish a mean. Then test the force required to remove teeth after various soaking times.
I don’t know where I’d get equipment to measure the force of a tooth removal.
Anyhow. I think the fact that the possibility exists of a dangerous situation should help folks to make a more informed decision on what to use.
King's Fine Woodworking thank you for that James.
Good advice & a great public safety message. It was good of you to take the time to make & post it. It shows your care & concern for others. I tried to give it 2 thumbs up. But UA-cam only let me do one. :-)
King's Fine Woodworking thank you so much James.
