Using some white vinegar in the rinse cycle helps a bunch. If you’re blessed with a double rinse machine, put a cup of vinegar in the first rinse. Otherwise, give an extra rinse. It helps pull out soap, body oils and leaves clothes soft and fresh. It should help pull out extra chemicals, too.
White vinegar also helps lock in the dyes, keeps the color longer, as I understand it.
Vinegar in the wash helps in our area. Makes the detergent more efficient, and it provides extra cleaning without adding harsh chemicals to the wash. Just don’t go with a cheap white vinegar.
