I dug through my photos and could not find a before pic of these Trenchers but you can sort of see the paint while they sit in the Simple Green. I let them sit for about a week (due to family stuff more than patience) and finally took a toothbrush to them. The Green did a great job. Everything was softened up and slid right off of flat surfaces. There are a number of crevices on these models that held the paint but I was able to get it out with an Exacto, though a toothpick probably would have been safer and easier on the models. There are still a few spots left but after 30 minutes of scrubbing and scraping, I decided it was good enough. The plastic bases were a little soft when I pulled them out but they seem fine today. They might have come off the mini's but the previous owner filled the bases with something like Milliput so they held.
Thanks for reading!
