Bleeding: adding ½ cup salt to your regular wash cycle can help prevent colors from running or bleeding.
Yellowing: For white cotton or linen items, a one hour soak in boiling water with one tablespoon salt and ¼ cup baking soda will remove the yellow tinge. For nylon, soaking in warm water with Epsom salt and rinsing in clear water will bring the white back out.
Ironing: To clean a sticky iron, set it on low and run it over a piece of paper with salt spilled on it. And to keep the iron from sticking to clothes in the future, add a pinch of salt to the laundry starch.
