Color-Absorbing Sheets: Benefits and Hidden Risks
Color-absorbing sheets use positively charged polyquaternium to capture negatively charged free dye molecules in the wash, allowing mixed-color laundry. However, reusing them can release trapped dyes, and their thin, lightweight material can clog washing machine filters, pumps, or hoses, so they should be counted, placed in mesh bags, and used cautiously with heavily bleeding fabrics.
