To make dishwashing liquid thicker, you can use a few common household items or commercial thickeners. Here are some options:
Salt: Adding common table salt to the dishwashing liquid can help thicken it. Start with small amounts and gradually add more until you achieve the desired consistency. Stir well to ensure the salt is fully dissolved.
Cornstarch: Mix a small amount of cornstarch with water to create a slurry, then add it to the dishwashing liquid. Heat the mixture while stirring until it thickens to the desired consistency. Be cautious not to use too much cornstarch, as it can leave a residue on dishes.
Xanthan gum: Xanthan gum is a common food thickener that can also be used in dishwashing liquid. Add a small amount at a time and mix thoroughly until you get the thickness you want. Xanthan gum can be purchased at most grocery stores or online.
Guar gum: Similar to xanthan gum, guar gum is a natural thickening agent. It can be added to the dishwashing liquid in small amounts while stirring until the desired thickness is achieved.
Commercial thickeners: If you prefer a hassle-free option, you can purchase commercial dishwashing liquid thickeners. These products are specifically designed to thicken liquid soap products and are readily available online or at specialty stores.
When adding any of these thickeners, it's essential to mix well and test the dishwashing liquid to ensure it still effectively cleans dishes without leaving a heavy residue. Additionally, consider the environmental impact of the ingredients you use, especially if you plan to dispose of the dishwashing liquid down the drain.
