Vinegar is useful for cleaning both the outside and inside of an iron. Scorch marks on the base, or soleplate, of the iron are scrubbed off with a combination of equal parts warmed vinegar and salt. After the soleplate is scoured, remaining deposits are wiped with a clean, water-dampened cloth.
Mineral deposits are removed by filling the iron's water reservoir with white vinegar. The iron is positioned upright on a heatproof surface and set to steam for five to 10 minutes. Then, the reservoir is filled with plain water, and the steaming process is repeated. After this stage, the reservoir is rinsed thoroughly with cold water. To be sure all residue has been cleared away, an old towel or scrap cloth is ironed on steam.
