Liquid laundry starch and ironing produce crisp clothing. Starch can be used at full strength to create a firm fabric perfect for crafts. Adding water to starch generates the right amount of stiffness for clothing and linens. Commercially manufactured starch contains chemicals that can be harmful if ingested by people or pets. You can make a safer starch with ingredients commonly found in kitchen pantries.
The only ingredients required to make laundry starch are cornflour and water; simply dissolve the cornflour in the water. The ratio of starch to water can vary for one tablespoon to four tablespoons of starch per pint of water. The more cornflour used, the stronger the starch will be.
Once mixed, starch should be stored in a clearly labelled spray bottle. Shake the bottle before each use to ensure cornstarch is dissolved. Organic cornstarch incorporates quickly because it is free of added chemicals. If you do not use the entire bottle of laundry starch, store in a refrigerator and bring it to room temperature before the next use.
Essential oils can be added to the starch for fragrance. Add six drops of essential oil per pint of starch. Lavender and vanilla are commonly used scents.
Laundry starch can be added to fabric during the wash cycle or as a pre-ironing spray. If you wash clothing with starch, spray them with warm water before ironing. As a pre-ironing spray, mist starch onto dry material just before ironing. In addition to stiffening laundry, starch can be used to make glue, paint and silly putty.
