Jim Is Hot: What kind of laundry detergent should I use for childrens consignment clothing?
I buy some of my son’s clothing at children’s resale shops. I bring them, wash, dry & iron the clothing just to give me the peace of mind that its clean & stain free. But you just never know with what the clothing fibers have. My question is: what kind of laundry detergent is best to wash clothing like this? What steps would you take to guarantee cleaniness of this clothing?

Thank you for your answers.

Use Arm & Hammer laundry detergent. It uses activated baking soda. If you want further protection, add one cup of distilled white vinegar to the final rinse water.
