Dry cleaning is necessary for certain garments which would be damaged by soap and water. But dry cleaning entails lots of nasty chemicals. Most garments to be dry cleaning do not have caked dirt and poop on them - these are fancy things, and usually just have some body odor.
Body oil and odor
is composed of volatile substances: grease, fatty acids etc. I propose that instead of solvents, high heat and pressurized air be used to clean these garments. The jacket or dress would be put in a chamber which would be pressurized to many atmosphered, and heated to a high temperature - this may need to be determined for various fabrics / synthetics.
The volatiles would be driven off by the heat, and the pressurized air would act as a solvent to capture them. This hot air could then simply be exhausted out the roof, after some heat is recaptured for the next load using an exchange mechanism.
This setup would also do a fine job of baking up croissants.

OR...use supercritical fluids (eg Carbon dioxide) |
|

Or just put it in the dryer. |

[contracts] this thing would be perfect for your silk shirts. On account of the many thick layers of cologne. We would need to put up rails to keep ladies from jumping into the exhaust vent. |
|
| |
The key would be how strong the micro air currents through and around the fabric would be, in this altered environment. |

If we've committed to the CO2 route, as those people in Korea
clearly have, then maybe we could use this to improve the
economics of Carbon Capture and Storage: here is the coal
power station, and right next door is the dry cleaner; when
the CO2 reaches its final destination down in the lithosphere,
we will bury with it the tantalizing hint of [contracts]'
cologne; a cologne that lingers even after [contracts]'

has been deleted. |

so what was [contracts]'s remark? |
|
| |
But the high temperatures are likely a problem with
shaped/delicate fabrics that need dry cleaning. Why not pull a
vacuum and the volatiles will boil off at Room temp? |
