For me, it's dog spit.
Dog spit is explicitly considered very impure in Islam. Therefore the ideal method of postwar execution for the IRGC members who killed Iranian and foreign civilians is to be bound, hoisted up by the ankles and lowered head-first into a 5-gallon bucket of dog spit using a block and tackle, preferably by a nice Jewish lady (presumably one who lost relatives in the war).
In dogs, saliva production can be stimulated by providing citric acid on a cotton swab, which dogs actively seek out and generally enjoy. Large breeds with a tendency towards drooling (i.e. St. Bernards) could reliably and sustainably produce more than one liter per animal per day with citric acid stimulation.
Since there will be some losses associated with aspiration, spilling and coating of surfaces, despite reasonable attempts at recovery, it's probably necessary for the number of animals to meet or exceed the intended maximum throughput in prisoners per day.
The current US market for St. Bernard dogs alone would easily support purchasing 100 animals, and their approximate 10 year lifespan requires purchasing about 10 per year for maintenance if necessary. This is an initial outlay of maybe $100k, realistically $200k if we include domestic transportation costs and logistics.
With the kind of wages likely in postwar Iran, you would easily be able to staff your kennel with, say, 50 full time personnel at even a very generous $10k/year and the operating costs would be negligible compared to the remaining costs: housing prisoners and holding trials.
