  1. Dry-cleaning? The solvents used tend to remove fats and oils. Failing this, you’ll need to use a mixture of Sodium Carbonate and sodium hydroxide. I’ve used a mix like this to clean shop towels. Also, if you can get it, trisodium phosphate also. You’ll want to do this in a big stainless pot, and heat it to 90 C or so - just short of boiling. Stir it good. It might devour some kinds of cloth, so try a sample if you can. This will take a while - an hour or more. It might need repeated instances, also. The second means could be hazardous, so I’d try dry cleaning first.
