Many Cascade and Finish products use bleach (sodium hypochlorite) in their formulas to fight stains. For example, Cascade Original Gel and Finish Gel both contain bleach. Some products do not contain bleach. For example, Cascade Free & Clear is bleach-free. If you’re looking for bleach-free detergent, read the ingredient labels carefully. If the ingredient list includes sodium hypochlorite, the product contains bleach.
