Can your cotton rug go in the washer? Check the label first
Even cotton flatweave rugs differ in shrinkage, wash temperature and backing; follow each product care label.
Small area rugs trap dust, but cotton does not automatically mean machine-washable. IKEA's cotton flatweave TIPHEDE is one washable example, with routine vacuuming, rotating and line-drying. Other rugs may have backing or finishes that prohibit machine washing; verify the label and washer capacity first.
