Thanks, Massaen, I'll try that.
From my understanding of the chemistry of such things there's exactly 2 possibilities:
1. What you said works and they're good again.
2. The Cleaner sucked some components out of the resin and absorbed them, thus making it a permanent issue I most likely cannot fix. Only option then would be to drill them out, pin them so the army and legs done wobble, cut off everything else that's too wobbly to work with and replace / resculpt the parts
