Anyone try TERSUS liquid CO2 cleaning for down garments?

I stumbled across Patagonia’s recommendation that their 1000 fill jacket never be cleaned with soap and water (even down-specific soap). Their instruction mention they send the jacket to Tersus for cleaning, which uses ‘liquid CO2’ , although my guess is they really mean Supercritical CO2 as I know SC is used in the oil extract industry, among other things. Seems like SC c02 would indeed be ideal for removing body oils and funk from down. Or is Liquid C02 something similar but different?

I see their jacket cleaning service is only $35 and a sleeping bag is $45. That’s not bad in my book. I have a 1 year old Plasma 1k that I’ve been contemplating cleaning, but am definitely not doing it myself or getting it wet. Same with a Hammock Gear quilt, it will be due for a cleaning in a year or so.

Anyone use this service? Any feedback on how well your garment was cleaned and if you noticed re-lofting after body oils were removed? Any of you genius science-y people have thoughts on SC C02 cleaning on down? From what i know it seems like an ideal application.

interesting.

price for bag cleaning goes up for higher FP down. I wonder what they do differently. Drop down has 750-850 FP but no higher.

Interesting topic. The TERSUS website is full of marketing content and says nothing about how they actually clean garments.

You were right to think of supercritical CO2.

Apparently there are liquid CO2 washing machines being delivered to the dry cleaning industry.

See http://e3tnw.org/ItemDetail.aspx?id=512. There are other websites showing photos of the machines.
