a diluted vinegar soak before laundering may help reduce some smells. Persistent mildew or visible mold may require a more appropriate laundry or cleaning treatment.
There is one safety rule that matters more than any laundry tip: vinegar should never be combined with chlorine bleach.
Important Safety Reminder
Never mix vinegar with chlorine bleach. The combination can produce dangerous chlorine gas. Keep vinegar separate from bleach and follow the care instructions for your garments and washing machine.
Vinegar is not suitable for every fabric or every laundry problem. When in doubt, check the manufacturer’s recommendations for the fabric and washing machine before using it.
