How to Tell What Your Rug Is Made Of
The single biggest factor in how a rug should be cleaned is what it's made of. Wool, silk, viscose, and synthetics each react differently to water, heat, and cleaning agents, and a method that's routine on one can permanently damage another. You don't need to be an expert to get a good idea of what you have.
Flip the Corner Over
The back of a rug tells you how it was made.
- Hand-knotted: the pattern on the back mirrors the front, and you can see individual knots. These are often wool or silk and usually the most valuable rugs in a home.
- Hand-tufted: the back is covered with a fabric or canvas backing glued in place. The adhesive is often latex, which breaks down with age and moisture.
- Machine-made: the back is uniform and grid-like, with perfectly even rows.
Look at the Fringe
On a hand-knotted rug, the fringe is the ends of the foundation threads running through the whole rug. On tufted and machine-made rugs, fringe is usually a separate strip sewn onto the ends.
Check the Sheen and the Feel
- Wool has a soft, slightly matte look, feels springy, and bounces back when pressed.
- Silk has a deep sheen that shifts with the light and feels cool and fine.
- Viscose shines like silk but feels slicker, and it crushes and stays flat in traffic.
- Synthetics like polyester and polypropylene often have a uniform plastic-like shine and a stiffer hand.
Read the Label, Carefully
Labels help, but marketing names can mislead. "Art silk," "bamboo silk," and "faux silk" all usually mean viscose. "Silk touch" is a description, not a fiber. If a rug is labeled silk and priced like a synthetic, it's worth a second look.
Why It Matters
Hot-water extraction that's fine on a synthetic can bleed the dyes on a hand-knotted wool rug, distort its foundation, and brown a viscose rug in a single pass. That's why we identify fiber and test dye stability before choosing any method. If you're not sure what you have, that's normal. We confirm it on site before anything gets cleaned.
