Yes, it’s true, you can use dishwashing liquid for laundry. I prefer Dawn brand but any brand will work. Keep in mind that Dawn produces a lot of bubbles so you don’t have to use very much – just use about an 1/8 cup and add to your washing machine just like you would regular detergent. It also works well to pre-treat stains – use it just as you would a regular product for pre-treating stains. I know some people use Dawn in a pinch but my aunt has actually exclusively used Dawn in place of detergent for years. She buys it in bulk from a warehouse store and uses it for dishes and clothes so saves money as well. Just don’t wind up with a basement full of bubbles like Daffy Duck or one of the Brady kids! Use sparingly!
