I have a Room size Wool Rug that was quite expensive.
If the fibers are in good condition then you can clean it with a Rug Cleaner like
this machine dose NOT HEAT the water.
I used a good amount of Wool Lite in the Clean water chamber. And I cleaned my rug as you would clean any rug. Then I went over the rug several times with just the suction on the rug doctor to make sure I got out as much on the water I couldn’t. Then I allowed it to dry completely.
WOW My rug came out Like New! It smelled soooooooo Good and It was in perfect shape.
Good Luck with your Wool Rug!!!
