Using traditional bleach for whitening sheets can have several drawbacks. Firstly, bleach is harsh on fabrics and can weaken fibers over time, leading to premature wear and tear of the linens. This can result in shorter lifespan for the sheets, requiring more frequent replacements. Secondly, bleach has a strong chemical smell that may linger even after washing, which can be unpleasant to sensitive individuals or those with allergies. Moreover, if not used properly or in high concentrations, bleach may discolor or damage fabrics instead of whitening them effectively.
