How to Use Purified Water in a Steam Iron

The impurities and mineral solids that exist in most home tap water systems can leave a residue both inside your steam iron and on your clothing, especially if your water system has a large amount of impurities. For this reason, you may choose to turn to purified water as an alternative. Purified water is less likely to leave stains on your clothing or clog your steam iron with mineral deposits. The instructions that come with most steam irons specify using tap water, but provide directions for switching to purified water.

Step 1

Unplug the iron's power cord from the electrical outlet.

Step 2

Turn the steam control to the "Off" position.

Step 3

Set the iron upright so the filling inlet sits horizontally.

Step 4

Mix 1/4 cup of tap water with 1/4 cup distilled water in a spouted container. Alternatively, use undiluted bottled spring water.

Step 5

Pour the distilled water mixture or spring water slowly into the water filling inlet until it reaches the maximum level as indicated by the marks on the inlet.
