I use Easy-Off oven cleaner. I let it sit overnight usually. Most of the time it does a good job. I\'ve listed my process below:
1. Spray models thuroughly in a well vented area
2. Let is and soak over night
3.Spray models again next day (too loosen dried Easy-Off
4. Let models sit 30 - 60 min
5. Brush under running water with stiff bristle toothbrush
6. use sculpting tool or dental pick to get the nooks and crannies.
Ocassionally this will warp a base or two but that is the most distortion i\'ve seen. Also occassionally the models get etched slightly by the chemical, but nothing that is noticeable after painting.
Hope this helps.
