Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Probably Not New to Some/most People
I was painting the fence at my place with a variety of paint (being creative)
Step 2: I Should Have Read the Paint Labels
I was dropping the used paintbrushes into my can of water for cleaning them.
Step 3: Oh, *^%*@!
Of course one of the colors was not water clean up. & the container of mineral spirits had nothing in it.
Step 4: An Ah-ha Moment!
As I was searching for another solvent, I spotted the WD40
I figured if it could de-gunk stuff....
Step 5: Nice!
The paint brush was clean!!!
I may not buy mineral spirits again.
WD40 doesn't evaporate it I don't tighten the cap enough
If you wanted to after absorbing the excess off..,
You could then use some nicer smelling stuff (soap) shampoo works great for greasy hands
