Potatoes are an excellent source of vitamin C, and one potato with the skin on also provides 620 milligrams of the mineral potassium. Potato skins contain essential dietary fiber and nutrients and should be eaten with the potato. But make sure potatoes are cleansed of any dirt and residue before preparing, cooking and eating them.
Fill a large bowl with warm water and add 2 to 3 tablespoons of white vinegar. The acetic acid in the vinegar helps to dissolve dirt and kill germs on the surface of the potato. You can also make a concentrated vegetable spray solution by combining a cup of vinegar with 3 cups of water in a spray bottle.
Place the potatoes in the water solution. Let them sit for a few minutes. Alternatively, you can spray each potato with the vinegar solution before washing.
Wash each potato under warm running water. Use a vegetable scrubbing brush to remove any residual dirt on the skin. Rinse the potatoes thoroughly to wash away any vinegar. You can also place them all in a strainer to rinse them together.
Place the washed potatos on a clean dish towel to dry. You can also wipe each one dry with a clean kitchen towel.
