After reading so many different threads on what product to use to strip paint of plastic models, I was getting a little confused. People's results even with the same chemicals seemed to vary wildly. The most common, Simple Green, is so rare in the UK as to not be an option and even with that peoples results varied.
I thought I'd run a little experiment. I'd just bought a load of marines from ebay, they were absolutely caked in paint and needed stripping. They were also old and cheap so if I melted a few I'd not be too bothered.
For my experiment I chose five different chemicals I could find around my house, well I went out an buy some ultra cheap multi surface cleaner as close as I could get to the one used by leighjt in his tutorial. Into a jar of each chemical I placed 2 or 3 miniatures, if possible something plastic and something metal
These were the results of the first attempt:
First off the brushes I used, an old toothbrush, a new stiff tooth brush and a wire brush
Vodka
Pilot00 suggested alcohol, he specifically said the type you get from the chemist, but I thought I'd try Vodka anyway. As you can see it did not work in any way. Lets just call this the control, an example of what 24 hours soaking in a non melty liquid and some vigorous scrubbing can do. I should have known vodka has no effect on a space marine, its right there in the fluff!
Foaming Oven Cleaner
Problem here seemed to be, after the foam died down the model was not actually soaking, so nothing much happened. Better than the vodka, but would still take many many attempts to get most of the paint off.
Cheap Multi Surface Cleaner
This result came after two soaks and some very vigorous scrubbing. Not bad though considering its by far the cheapest chemical here. Still bits in the cracks, which is unfrotunatly exactly where I was trying to remove it from, so a spray prime won't obscure the detai.
