That claim is exaggerated and mostly social media “life hack” hype.
Putting an empty plastic bottle in a washing machine is sometimes shown online as a trick to:
- “improve washing”
- “save water or detergent”
- “reduce wrinkles or tangling”
But in reality:
What actually happens
- A loose plastic bottle just bounces around with clothes
- It can create noise or even damage delicate fabrics
- It doesn’t meaningfully improve cleaning performance
- It can stress the drum or get trapped in clothing
Why people share it
These posts are usually framed as “genius hacks” to get attention, not based on laundry science.
What does help washing performance
If the goal is better cleaning or fabric care:
- Proper load size (don’t overfill)
- Correct detergent amount
- Sorting fabrics
- Using appropriate wash cycles
So no, it’s not a sign of “high IQ”—just a viral trick without real evidence behind it.
If you want, I can go through other “viral hacks” and tell you which ones actually work and which ones are nonsense.
