They probably used something like oxalic acid (standard rust remover). The heating was probably to allow for enough expansion to allow the liquid to get into the tight spaces. Then rinse with distilled water and maybe finish with an isopropanol rinse. Sounds like a clever approach to me especially since there was little to lose.
'Oxalic acid marine cleaner' is widely used on boats--just add water.

you can read up on the technology at

a down side is that the camera will have a fixed f number as the f number of the main lens and the micro lenses need to be the same (my guess is that the first model will be at f/4)
getting this to work with a zoom will require lots of tradeoffs

this is for the point and shoot market and not for the DSLR folks
seems that this could be adapted to cell phone type cameras as well
