Modelhaus has always recommended Bleechwite, however I asked them about Super Clean, that they also recommend. They said it will work but would turn the resin purple. They also recommended Marine Clean, a Por 15 product now labeled Por 15 Cleaner/Degreaser.
Since you apparently had issues with the purple cleaners, I would try to avoid them or test a scrap piece before immersing the whole kit in the "purple pond".
