Sheep’s Wool Checkerboard Rug Cleaning in West Linn, OR

A high-pile sheep’s wool checkerboard rug from West Linn’s Willamette neighborhood was dry-dusted, enzyme pre-treated, gently hand washed and returned home without shrinking, felting or dye bleeding.

Dry soil removal, a bio-enzyme pre-treatment, a gentle low-moisture hand wash, thorough extraction and climate-controlled drying.
The result
Embedded dirt and pet hair were removed, the plush texture came back and the checkerboard pattern looks bolder. The rug did not shrink, felt or bleed.

The Situation

This is a high-pile sheep’s wool rug with a bold black-and-white checkerboard pattern, from a West Linn home in the Willamette neighborhood. Years of life in a rainy, hilly part of Oregon had worked grit, pet hair, pollen and moisture deep into the shag. The owners loved the rug, and they worried that harsh cleaning would shrink it, felt the wool or make the dyes bleed.

What We Found

Natural sheep’s wool can shrink and felt if it is handled roughly or dried badly, and a dark-and-light pattern shows any dye movement. So we started with a detailed inspection of the wool type, the dyes and the construction before choosing a method.

How We Cleaned This Wool Shag Rug

  1. 1

    Detailed inspection

    We evaluated the wool type, the dyes and the construction before choosing a method.

  2. 2

    Dry soil removal

    A large amount of grit and pet hair was removed without moisture, before any washing.

  3. 3

    Bio-enzyme pre-treatment

    A bio-enzyme treatment targeted organic soils and pet stains.

  4. 4

    Gentle low-moisture hand wash

    We hand washed the rug with wool-safe, low-moisture solutions to protect the natural fiber.

  5. 5

    Thorough extraction

    All residue was extracted so the wool would not re-soil quickly.

  6. 6

    Climate-controlled drying and grooming

    The rug dried in a climate-controlled room and was groomed to bring back the plush, shaggy texture.

  7. 7

    Final inspection and delivery

    We inspected the finished rug and delivered it back to the West Linn home.

The Result

When the rug came back, the embedded dirt and pet hair were gone and the plush, shaggy texture had returned. The black-and-white checkerboard looked bolder, and the owners’ three worries did not happen: the rug did not shrink, felt or bleed in the wash. Results depend on a rug’s age, dyes and wear, which is why we inspect and test first.

Care Tips for This Kind of Rug

  • Vacuum shag wool slowly with the beater bar off or with a suction-only tool.
  • Rotate the rug every few months, and brush out pet hair before it works into the pile.
  • Plan a professional wash about every 2 years, or every 12 to 18 months with pets or an active household.
