Yes, You Can Wash Out Starch: How to Reverse Stiffened Laundry and Pre-Rinse Food
Starch is a natural polymer used to stiffen fabrics for a crisp, wrinkle-free look, or it can be a sticky, unwanted byproduct in many cooking applications. Fortunately, in both scenarios, it can be effectively removed. The process for washing out starch depends heavily on the context, whether you are dealing with clothing, rice, or other items. For textiles, the solution is usually a simple laundry routine, while for food, it involves specific rinsing techniques. Understanding the different approaches ensures successful removal and optimal results.
Washing Starch Out of Clothes and Fabric
Over-starching can make clothes uncomfortably stiff or cause a yellowing effect over time. The key to removal is to break down the starch and rinse it away thoroughly. Here is a list of steps to follow:
- Regular Wash Cycle: For most cases of moderate starch, a standard machine wash with a good-quality laundry detergent is all that's needed. The agitation and cleaning power of the detergent will loosen and dissolve the starch from the fabric fibers.
- Warm Water Soak: For heavily starched items, a pre-soak is highly effective. Fill a basin or your washing machine with warm water and let the item soak for 30 minutes to an hour. This will help to break down the starch before the main wash cycle.
- Add White Vinegar: As a natural softener and mild acid, white vinegar is excellent for breaking down starch bonds. Add ½ to 1 cup of white vinegar to the rinse cycle. The vinegar smell will dissipate as the clothes dry.
- Use Fabric Softener: For a more conventional approach, a commercial fabric softener can also be used in the rinse cycle to help restore the fabric's softness and counter the stiffening effect of the starch.
- Check the Care Label: Always check the garment's care label before using hot water or strong agitation, especially for delicate fabrics like wool or silk, which should not be starched in the first place.
Removing Starch from Rice for Cooking
Rinsing rice is a common practice in many cuisines to achieve distinct, non-clumpy grains, such as for a pilaf or fried rice.
- Measure the rice: Put the desired amount of rice into a bowl.
- Add cold water: Cover the rice with cold water and use your hand or a whisk to gently swirl the grains. The water will turn cloudy as surface starch is released.
- Drain and repeat: Pour out the cloudy water carefully, using your hand or a fine-mesh strainer to prevent losing any rice. Repeat this process two to three more times until the water runs mostly clear.
- Soak (optional): For some rice varieties, a short soak after rinsing can further improve texture. Soak for about 30 minutes before cooking.
- Drain thoroughly: Before cooking, ensure all excess water is drained from the rice.
Comparison Table: Methods for Washing Out Starch
| Feature | Method for Laundry | Method for Rice | 
|---|---|---|
| Primary Goal | Soften fabric, remove stiffness, reverse yellowing. | Achieve fluffy, separate grains; reduce stickiness. | 
| Main Ingredient | Water, detergent, optional vinegar or softener. | Cold water. | 
| Temperature | Typically warm for effective starch breakdown; consult care label. | Always cold water to prevent starch gelatinization. | 
| Technique | Standard machine wash, pre-soaking, agitation. | Rinsing and swirling in a bowl until water runs clear. | 
| Duration | One full wash and rinse cycle, plus optional soaking. | Multiple rinses, typically a few minutes in total. | 
| Expected Result | Softer, less stiff fabric; removal of yellowing. | Grains that are not sticky or clumpy. | 
The Science Behind Starch Removal
For fabrics, starch is a carbohydrate polymer that holds fibers in a specific, stiff position. Washing with water and detergent provides the necessary chemical and mechanical action to break those bonds and lift the starch off the fabric. Adding white vinegar introduces a mild acid that further assists in breaking down the stubborn residue. For rice, the goal is simpler: physically rinsing away the surface starch that would otherwise cause the grains to stick together and become gummy when cooked. The use of cold water is crucial for rice because hot water can cause the starch to gelatinize, making the grains even stickier and more difficult to separate.
Conclusion
Yes, you can wash out starch, and the method is straightforward for both fabric and food. A simple machine wash or a few rinses with cold water can successfully reverse the effects of starching, whether intentional or not. By understanding the different requirements for laundry versus culinary tasks, you can effectively manage starch content and achieve the desired outcome. For clothing, a standard wash often suffices, with vinegar or a pre-soak assisting with heavier applications. For rice, the process of rinsing until the water runs clear is a time-tested technique for ensuring fluffy, separated grains.

Frequently Asked Questions
Can hot water set starch into clothing? No, hot water does not set starch into clothing in the same way it sets protein-based stains. In fact, warm or hot water (depending on the fabric) is often recommended to help break down and dissolve starch more effectively.
Will removing starch damage my clothes? No, removing starch with proper washing techniques, like those using detergent and vinegar, will not damage your clothes. It is a standard laundering process for items that have been starched for a crisp finish.
Is it safe to put vinegar in my washing machine? Yes, adding white vinegar to the fabric softener dispenser during the rinse cycle is safe and effective. It helps break down detergent residue and starch without harming your machine.
How can I tell if there is still starch on my clothes after washing? After drying, if the clothes still feel stiff or if you notice a white, powdery residue, it indicates that some starch remains. You can repeat the washing process, potentially with a pre-soak.
Does washing rice remove all of the starch? Washing primarily removes the surface starch. The starch inside the grain remains. For dishes requiring creamy, sticky rice (like risotto), you should skip rinsing to retain this inner starch.
Why is cold water better than hot water for washing rice? Cold water is used to rinse rice because hot water can cause the surface starch to gelatinize and become sticky, making it counterproductive to the goal of separating the grains.
What if my clothes were heavily starched at a dry cleaner? For heavily starched items, especially those from commercial dry cleaners, you may need a more aggressive approach. Start with a prolonged warm water and vinegar soak before running a complete wash cycle.
