Well what is the update?I do Dry Ice Blasting but have yet to try it on Commercial Kitchens (restuarants). I've done a little but of 'grease' in the past, works pretty good - have to control the spray though, you basically 'move' the grease. I've cleaned a couple Industrial compressors that had grease/grime on them - used a little de-greaser to 'loosen' things up and it worked well enough.
I may be attempting a kitchen next week - update after I do.
True - Dry Ice Blasting is not cheap - media is fairly expensive so it's charged accordingly - most Co's charge about $200/hr when blasting.
