The brick walls and ceiling are covered in a grime.
New walls are being built with insulation along all the exterior brick walls so they will be covered however they still need to be cleaned.
The ceiling is going to stay open and it is going to be painted once it is cleaned.
What is the best practical way to clean this coating of grease off everything?
We are happy to rent required equipment.
Thanks

So the walls are brick but the ceiling is?? If it's a hard surface I can probably help you out. Porous or absorbent requires a little more analysis. Can it be simply pressure washed or foamed, or does it require some dwell time to loosen up the dirt?
Rule 1 is what is the nature of the fouling? Simple oil? Oily based? Carbon soot? Everyday buildup of dirt, and dust? There might be some very good, non toxic, non flammable, and safe to atomize products that will do every bit as good a job as an industrial solvent. solvents are great for tar and bitumen emulsifying. rarely required for anything else.
Rule 2 is to read the msds for the product you intend to use. The aforementioned Biosol product, like many of their products, is probably not as safe as they like to say they are. Gotta love open cup flashpoint ratings.
Rule 3 is it's usually not a great idea to ask a general forum what they'd use when they probably have no idea what the fouling is comprised of and by and large do not have any idea what's dangerous and what isn't.
I'm anxiously waiting for someone to recommend a lovely d'limone based orange solvent. Because they're so biodegradable and dammit...they smell good. 43C flashpoint, eye and respiratory damage be damned.
