Liquid starch is used to stiffen fabrics for a crisper look that resists wrinkles. This starch may be either poured into your washing machine in the final rinse cycle or sprayed onto fabric before ironing. Many brands of commercial starch are available, but you can easily make liquid starch at home. Making your own starch can save you money and, since you can reuse the bottle over and over, it is better for the environment.
Remove the lid on a clean spray bottle. Place two tbsp of cornflour into the bottle.
Fill the bottle with one pint of cold water from your faucet. Replace the lid on the bottle and then use a permanent marker to label the bottle.
Shake the bottle vigorously to mix the cornflour with the water. Spray the liquid starch directly from the bottle on fabric to stiffen it, or add it to the final rinse cycle when washing clothes. Use one cup of this liquid starch, if you are doing the latter. You can add more or less if the stiffening results are not to your preference.
Shake the bottle before each subsequent use to mix the ingredients. Store the bottle in a cool area of your home and replace with a fresh batch if it becomes discoloured or acquires an odour.
Liquid starch may also be used in crafts -- it can be sprayed to stiffen paper, lace or other materials.
