Concluding my little test, I scrubbed the two Dettol minis and they came out... ok....
But the minis had a grey residue on them that was sticky to the touch, like band aid glue, that just wouldn't come off in the warm soapy water I prepped for rinsing them.
So I set them aside.
Then I opened and cleaned the 1st of two tubs of the large batch of minis I wanted to clean. You know; the ones in the St. Marc?
And the paint just fell off completely!
And mean completely! I used the toothbrush, but the rinse alone would have taken 90% right off. Where I did need the brush, it was in deeper recesses, and then everything came off like magic.
The only place where I needed to use some toothpicks was on the basing material, which got all goopy, but went off easily too.
So St. Marc for the win!
It's being used around here by professional house painters to degrease walls before painting over them, and that's what I was using it for too. But now it's also my go to (acrylic) paint stripper.
Also, it's cheap and readily sold in DIY stores and even stores like Action!
I will continue to test it though, on both plastic miniatures and enamel paints, as those were lacking in my test.
Oh, and here are the cleaned minis after 3 days in their bath plus a light scrub. They look as new and honestly, I've never ever cleaned minis back to this level before...
