The Easy Way to Clean That Gross Laundry Detergent Cup
If you’ve ever poured laundry detergent and cringed at the sticky, gooey mess coating the measuring cup, you’re absolutely not alone. That grimy buildup isn’t just unsightly, it’s also wasteful and frankly quite disgusting. But here’s the brilliant news: cleaning that detergent cup is far easier than you think, and you’ve probably been overthinking it this whole time.
The simplest solution? Chuck the dirty cup straight into the washing machine with your clothes. Yes, really! This game changing method eliminates all that tedious scrubbing and rinsing, giving you one less chore to worry about.
Let’s explore this clever trick and other effective ways to keep your laundry routine as smooth as possible!
Why Your Detergent Cup Gets So Disgustingly Sticky
Before we tackle the cleaning methods, it’s worth understanding why detergent cups become such a nightmare to clean. Modern laundry detergents are formulated to be highly concentrated, which means they’re thick, sticky, and designed to cling to fabric fibres. When you pour detergent, residue naturally coats the measuring cup, creating that familiar slimy layer.

This residue isn’t just unpleasant to look at. Over time, it can become a breeding ground for bacteria, affect the accuracy of your measurements, and even impact how well your detergent works. Plus, let’s be honest, nobody wants to handle a grimy cup every time they do laundry!
The good news is that detergent manufacturers actually design their products to be water soluble. This means that stubborn residue will dissolve beautifully when exposed to hot water and agitation, which is exactly what happens inside your washing machine.
The Revolutionary Washing Machine Method
Here’s the method that’s been making waves on social media and changing lives across the country: simply toss your dirty detergent cup into the washing machine along with your clothes.
This works because the hot water, detergent, and agitation of the wash cycle do all the hard work for you. The residue dissolves completely, your cup comes out sparkling clean, and you haven’t wasted a single minute scrubbing at the sink.
How To Do It
Pop the grimy cup into the drum with your clothes before starting the cycle. The cup will bounce around gently during the wash, allowing the water and detergent to reach every corner and crevice. When the cycle finishes, you’ll find your measuring cup looking like new.
This method works with both powder and liquid detergent residue. It’s particularly effective for those stubborn, dried on bits that seem impossible to shift with regular rinsing. Best of all, it doesn’t affect your clothes in any way, the cup is made from the same materials that are already safe for your washing machine.
Make sure your cup is dishwasher safe plastic or similar material that can handle the heat and movement of a wash cycle. Most detergent cups are designed to withstand this treatment, but it’s worth checking if you’re unsure.
Quick Techniques For Daily Maintenance
While the washing machine method is fantastic for deep cleaning, you might want to give your cup a quick rinse between uses to prevent heavy buildup.
Here are some speedy techniques that take less than a minute:
The Hot Water Flash Rinse
Immediately after pouring your detergent, give the cup a quick blast of hot water from the tap. The heat helps dissolve any lingering residue before it has a chance to set. Swirl the water around for a few seconds, then tip it out.
The Washing Up Liquid Swish
Keep a small bottle of washing up liquid near your laundry area. Add a tiny drop to your cup with some warm water, give it a quick swirl, and rinse clean. This method cuts through grease and sticky residue effortlessly.
The Prevention Method
Some people prefer to rinse their cup with cold water before adding detergent. This creates a barrier that makes cleanup easier afterward. While this requires an extra step upfront, it can save time in the long run.
Troubleshooting Common Detergent Cup Problems
Even with the best intentions, detergent cups can develop issues that require specific solutions:
Cloudy Or Stained Plastic?
Over time, some plastic cups develop a cloudy appearance or permanent staining. This is usually caused by hard water minerals or certain fabric softeners.
Try soaking the cup in a solution of white vinegar and water overnight, then scrubbing gently with bicarbonate of soda.
Persistent Odours?
If your cup has developed an unpleasant smell, it may have trapped bacteria in microscopic scratches.
Fill it with a mixture of hot water and a tablespoon of bleach, let it sit for 10 minutes, then rinse thoroughly. Always ensure proper ventilation when using bleach.
Cracked Or Damaged Cups?
Scratched or cracked measuring cups are harder to clean and more likely to harbour bacteria. These are also more prone to breaking during the washing machine cleaning method.
When in doubt, replace the cup entirely, most supermarkets sell universal measuring cups that work with any detergent.
Remember that measuring cups aren’t meant to last forever. If yours is showing significant wear after months or years of use, investing in a replacement might be more practical than fighting with a damaged cup.
Your Detergent Cup Will Never Be Gross Again
Cleaning your laundry detergent cup doesn’t have to be a dreaded chore that leaves you scrubbing sticky residue at the sink. Whether you choose the revolutionary washing machine method, quick daily rinses, or occasional deep cleaning sessions, you now have all the tools to keep that cup sparkling clean.
The washing machine trick alone will save you countless minutes of frustration and ensure your measuring cup is always ready for the next load. Combined with smart storage solutions and simple maintenance habits, you’ll never have to cringe at a grimy detergent cup again.
