I usually use a black marking pen for layout. I don’t think it the safest practice to be mixing volatile chemicals in the home shop.
For scraping of precision surfaces I like Prussian Blue.

He's using ethanol. One of the safest thinners out there.
If you use WD40 you are using a more dangerous mix of acetone and cooking oil. Acetone like alcohol is easily absorbed through our skin. Acetone however is known to cause cancer if used without proper precautions.

"Acetone however is known to cause cancer if used without proper precautions."
Germany has a 'MAK-Liste', which lists the max. permitted concentration of solvents (et al.) at a workplace. Acetone's value is 1200mg/m3 - which is much higher (means: safer) than other solvents used in workshops. Because of its high flammability Acetone is practically not in use anymore, though. MAK-Liste: Acetone is not known to be and not listed as a cancerogene.

You're not behind: other countries - other rules. vapor or liquid depends on the temperature: At 68 F a 'petri dish' of acetone will be evaporated within half an hour.
But by mixing and applying our machinist's blue we will be exposed to this just a few seconds. Not more than our wives doing their nails.

Yes , great, this is also difficult to get here in France, appart from spray cans which I don't find to be convenient for the small parts I work with.
Nothing harmful here, alcohol and shellac is what we use every day (... well we should... ) in the wood shop .
I am really happy to learn this is that easy to make marking fluid, I think I already have the ingredients in the shop, will give it a try very quickly!
Thanks Jon for that finding!
(PS Jon, for once, I think you could win a tool of the week by proxy with this one !
