To clean, as old-school as they come: take rug outside, hang and whack away with a broom, take rug back inside and vacuum, pour capful of Woolite (or similar product) in a bucket of cold water, before starting work test a small area. Apply your cleaning solution with a damp sponge working the direction of nap, to rinse take a new clean sponge and dampen with cold water only and work the direction of nap. Repeat as necessary. Hang dry. Do not walk on the rug until it is dry. Clean wool rugs professionally, select a reputable, professional rug cleaning business.
