This Surprising Detergent Trick Will Make Your Bottle Last Twice as Long!
If you are like most people, you probably toss your laundry detergent bottle in the recycling bin when it feels empty. But what if we told you that you could get several more washes out of that “empty” bottle?
Many people unknowingly throw away a significant amount of detergent that gets stuck inside the container. With just a few simple tricks, you can double the lifespan of your detergent and save money on every wash.
Are You Wasting More Detergent Than You Think?

Liquid laundry detergent is thick and often clings to the sides and bottom of the bottle, making it difficult to pour out completely.
Over time, detergent residue builds up, leaving more product inside than you realise.
Manufacturers design bottles with spouts that make pouring easier, but they also trap liquid inside, preventing you from getting every last drop.
Instead of wasting detergent, try these proven methods to maximise your bottle’s lifespan and keep your clothes clean for longer.
1. Remove the Spout to Access Hidden Detergent
One of the easiest ways to recover leftover detergent is by removing the spout at the top of the bottle. This plastic insert is designed to control the flow of liquid, but it also prevents the last bit of detergent from pouring out.
How to do it:
- Grab a pair of pliers or an adjustable wrench.
- Grip the plastic spout firmly and wiggle it back and forth until it loosens.
- Once loosened, pull the spout out completely to reveal the trapped detergent inside.
- Pour the remaining liquid into a measuring cup or directly into your washing machine.
This method can unlock enough detergent for several more washes, meaning you get more value from every bottle.
2. Flip the Bottle Upside Down for an Easy Drain
If removing the spout seems tricky, another effective trick is to invert the bottle and let gravity do the work. This simple hack ensures that every drop is used, reducing waste and stretching your detergent further.
How to do it:
- Place the bottle upside down in a cup or container.
- Let it sit for a few hours or overnight to allow the detergent to slowly drain down.
- Once the liquid has pooled into the container, use it as usual for your next load of laundry.
3. Add Warm Water to Get the Last Drops
When you think your bottle is empty, there is usually a thin layer of detergent still clinging to the sides. A quick way to make use of this is by diluting it with water.
How to do it:
- Fill the bottle with warm water (about one quarter full).
- Close the cap and shake the bottle vigorously to loosen the remaining detergent.
- Pour the soapy mixture directly into your washing machine for an extra load or two.
This method is particularly useful for high efficiency (HE) washing machines, as they work well with diluted detergent.
Important Note: If you are using gel based detergents, this method may not work as effectively. Gel detergents are designed to be thick and concentrated, and diluting them with water can cause them to lose their cleaning power or become difficult to dissolve properly in the wash.
4. Cut Open the Bottle for Maximum Savings
For those who want to get every last drop, cutting the bottle open is a foolproof solution. This hack works best with thick, concentrated detergents, where residue builds up along the bottle’s interior walls.
How to do it:
- Using scissors or a utility knife, carefully cut along the sides of the bottle.
- Open it up and scrape out the remaining detergent using a spoon or spatula.
- Transfer the leftover detergent into a container for future use.
Store Your Bottle Correctly to Prevent Waste

Preventing detergent waste starts with proper storage. Most people store detergent bottles upright, which causes liquid to settle at the bottom and dry up over time.
Instead, try keeping your detergent bottle slightly tilted or on its side when nearly empty. This allows detergent to flow towards the spout, making it easier to use every last drop without struggling.
Why These Tricks Work and Save You Money

Laundry detergent may seem like a small expense, but over time, the cost adds up. Instead of wasting perfectly good detergent, these simple techniques allow you to get the most out of every bottle.
Whether you remove the spout, flip the bottle, or cut it open, you will be surprised at how much extra detergent is left inside.
With these methods, you can:
- Get up to twice as many washes from the same bottle.
- Save money by maximising every purchase.
- Reduce plastic waste by using up products fully before recycling.
- Make laundry day more efficient by having detergent available when you need it.
Next time you are about to toss out an “empty” bottle, try one of these tricks first and you might just get a few more loads of clean laundry for free!
