I can try to answer your questions but I doubt it will change your disgust of the process. LOL
Yes your clothes would be cleaned with everyone else’s!
Loads are separated sort of the same way you’d separate laundry loads
(but not exactly) one would not clean a white wedding dress with a red angora sweater!
The solvent isn’t stagnate! It’s not like water that can grow mold. Nothing can grow or live in it.
When machine is running, there’s a pump that is continuously pumping solvent (that has a percentage of detergent added to the tank it draws from) through a set of filters (shown below) into the drum where the clothes are tumbling then back through filters ect
When cycle is complete the drum spins and solvent goes back into the working tank from which it came. During dry cycle the heat/air causes the solvent remaining in fabrics to vaporize and turn back into a liquid (like distilling water) thats captured and turned into pure solvent and is piped back to either the machines working tank or into the machines second tank. There’s few reasons to rinse..you’d be rinsing with solvent!
It is, and always has been the dry cleaners job to capture as much solvent as possible as the stuff ain’t cheap to order. I’m sure that todays modern equipment dose a much better job than then when I was working in the industry.
At the time I left the profession OSHA was trying to issue new permissible exposure limits for perc from 100 ppm for eight hour day to 25 ppm.
I don’t know if this was ever achieved..cuz I got out.
Yes there were sealed metal drums with lids. One for waste from cooking off solvents (as explained in the other thread) a company Safety Klean picked up the waste drum. No hazmat suit. No it wasn’t dumped somewhere. That Co had the ability to cook off more than our still could and extract more pure solvent reducing waste.
Laundress might be interested in the Spotting chemicals I remember on the spotting board.
Streetex
209
Picrin
Pryrtex
Ammonia Hydroxide (50 50 water)
Sodium Perborate ( requiring heat from steam gun)
Perc fumes didn’t interfere with my memory of all this.
Wait why am I writing this..
LOL
