Vinegar is a natural and non-harmful fabric softener and descaler that also helps you get rid of bad odors. This way, your laundry comes out of the drum clean, and odor-free. For this you can best use cleaning vinegar. You can also use natural vinegar, but cleaning vinegar is more powerful, so you need less of it. You cannot use vinegar as a substitute for detergent. Although it kills certain bacteria, vinegar unfortunately does not dissolve stains. What it does do, however, is ensure that the colors of your laundry are better preserved and do not bleed.
