Limited Effectiveness: While mouthwash is antibacterial, the concentration in household mouthwash is much lower than laundry detergents or bleach. It won’t disinfect your clothes effectively.
Potential Risks: Alcohol and coloring agents in mouthwash may stain fabrics or fade colors. It could also foam excessively or damage your washing machine over time.
Better Alternatives: Use proper laundry detergents, fabric softeners, or laundry sanitizers designed for washing machines. Essential oils can be added for fragrance safely.
Bottom Line
Putting mouthwash in your washing machine is not recommended as a cleaning or disinfecting method. It may smell nice briefly, but it’s not a substitute for detergent and could harm your clothes or machine.
