|Before and after toothbrushing|
The toothbrush worked well but did not completely remove the paint in the grooves and undercuts so after rinsing in clean water I put the figures back for a further soak. I feel that relying on the chemical reaction as far as possible is preferable to physical action to remove the paint, but I accept that more brushing will be needed. I didn't replace the Simple Green at this stage, but reused the liquid the figures had already been soaking in. This may not be optimum, but I think the liquid is still active as it is quite warm.
A few pikes came adrift. Simple Green is said to dissolve superglue, but this was probably mainly caused by handling and a very minor issue in any case.
