Blade cleaning

[usernumber1]

Hello all.  I did some research - well, used Google.  I dug up this...https://www.federalcarbide.com/corrosion_resistant_tungsten_carbide_grades.html
the article talks about the corrosion resistance of tungsten carbide and it's binder agent.  I get the impression that Tungsten Carbide teeth are a mixture of Tungsten Carbide crystals and a binder material, either Cobalt or Nickel.  Seems like the two different binders are affected by different pH values, low pH (acidic) seems to corrode the binder.  Both materials seem to be OK with high pH (caustic) materials.
I checked the details of the Lidl W5 degreaser and it's caustic, I don't know how much but it's pH is about 10 (which is caustic).  Reading the back of the bottle, it lists "highly corrosive / hazardous" and "risk of sever damage to eyes" - probably best I keep the stuff away from the children.
I checked the Simple Green MSDS (material safety data sheet) and it lists Sodium carbonate and a pH of about 10.https://www.simplegreen.co.uk/index.php/material-safety-data-sheets/category/1-msds?download=16:crystal-simple-green

Has anyone seen a blade that's been damaged by cleaning with caustic cleaning agents?
Regards
Bob

don't think you're going to find any real world examples of this beyond purposeful abuse. there's a lot of FUD on the internet

My go to kit since it checked all my boxes at a low price as well. I just buy more of their cleaning solution when I run low. The cleaner seems to work better than Simple Green for me, and I’ve never tried Oven Cleaner type cleaners since I’m always cleaning the blades or bits in my basement shop, where ventilation can be an issue.

I've been using oven cleaner for years, and not had a problem.

I know very few will believe it but hot water works with no additives.

Oven cleaner here, it works so quickly that I am not concerned about it harming the carbide or its binding to the blade.  I have a Forrest WWII that I have been cleaning with oven cleaner for at least 25 years.  Sent it back to Forrest for sharpening a few years ago and it cut better than new after they tuned it up.

It works on ceramic mugs also, and is generally accepted as safe. 
  Rinse well, add some WD-40 after cleaning...

Wait a minute.... ???
