On a Thursday in early October, my elderly German Shepard had a bad day and peed on the wool living room rug. Not one but twice. It was a LAKE of dog pee in the center of the rug. It is a lovely 8 x 10, high quality rug that I bought at deep discount several years ago. Original price -- $900. I scored it for $200.
Professional rug cleaning would cost more than I paid for the rug. The day she peed on it, I cleaned it as best I could while it was still in the living room (it was a workday).
Three days later, on Sunday morning (10/4), I rolled it up and dragged it outside and laid it face down on the driveway. I put on my rain boots and knee pads (left over from a DIY floor sanding project) and got out the laundry detergent and a scrub brush. I scrubbed and scrubbed, the "wrong" side of the rug first. Then I grabbed a cup of coffee and sipped coffee while I rinsed the rug thoroughly using the cold water hose.
Then I flipped the rug over -- not easy for a 8 x 10 sopping wet wool rug -- and repeated the scrubbing from the "right" side of the rug. I enjoyed a second cup of coffee while rinsing it again.
I left it in the driveway for the whole day. Fortunately, it was sunny and warm. At the end of the day, my son, his gf, and I dragged the rug into the garage. I had set up two saw horses with a ladder laid across them. We dragged the rug onto the ladder so it could dry.
My word, but it stank to high heaven. I was quite sure that my efforts would be no good. Wet wool and wet dog combined. Oy.
A week later, it was still funky. Two weeks later and the funk was fading. We're almost at the three week mark and yesterday I did a thorough nose-test. No smell!
I hauled it down off the ladder/ saw horse contraption and laid it on the driveway for a good vacuuming. Then I rolled it up and dragged it back into the house. No smell and the rug is cleaner than it's ever been since it arrived.
