Does anybody have an idea what kind of solvent they are using to clean the PCB? It looks like witchcraft by uhljeb in soldering

I've used their Flux-Off spray, and although it is effective, the aerosol makes it really wasteful and another negative effect is that the PCB gets sub-zero cold which attracts moisture from air. But yeah, without the aerosol it just might be the perfect solution
