Sounds like the solvents SWIU chose weren't "dry" enough. That 70%, can't be used nowadays cause of the DMF(Dry Matrix Formulation). Those white chunks are a result of bloating, due to the water activated DMF.

The whole mess will be hard to evaporate, but if it can be done, then a WATERLESS A/B could save/recover some of the pseudo.

yeah also he let it sit for way too long. 24 hours will make that soly soak up most the gakk too. you want to use cold soly and only let it sit long enough for the dust to settle (like 30 minutes top)
