One of the biggest culprits is the washing machine itself. In top-loading machines, the central agitator can twist and pull lightweight fabrics during wash cycles. Over time, this constant movement weakens fibers and creates tiny tears that eventually become visible holes. Even front-loading machines can contribute to wear when clothes rub against one another repeatedly.
Another common source of damage is metal hardware. Open zippers, jean buttons, belt buckles, bra hooks, and decorative fasteners can scrape delicate fabrics during washing and drying. Cotton T-shirts, sleepwear, athletic clothing, and lightweight knits are especially vulnerable. What starts as minor friction eventually turns into noticeable holes after repeated wash cycles.
