Luis don't brake the seal. Jarred, have to admire your spirit! Luis does offer good advice. but he left off one test. After figuring out natural vs. synthetic, if you think its natural fiber, take your planned cleaning agent and on an inconspicuous area, and check for dye run. Even if its solid color, no need to create a blotchy appearnace. Most likely you will not have a problem with it.
My suggestion would be to use a neutral to slightly alkaline presray in a trigger bottle. Mist on, agitate with a horse hair brush, and use an acidic
all fiber rinse in your porty to extract with. Keep your pressure low, take your time, do lots of dry strokes. If it has a pile, make sure to groom it all in the same direction immediatly after and after drying. And use fans to get it dry as quick as possible.
