That “empty plastic bottle in the washing machine” trick is another viral hack that sounds clever but is often misleading or unnecessary.
What people claim it does
Posts usually say it will:
- Reduce lint or pet hair
- Improve washing performance
- Save detergent or water
- Prevent clothes from tangling
What actually happens
In most washing machines, an empty plastic bottle:
- Simply floats and tumbles randomly
- Does not have a controlled cleaning effect
- Can sometimes interfere with drum movement
At best, it does nothing noticeable. At worst, it can:
- Get stuck or damaged
- Create noise
- Reduce washing efficiency in some loads
- Potentially stress machine parts over time (especially front-loaders)
Where the idea comes from
This hack likely comes from misunderstanding how:
- Mechanical agitation works in washing machines
- Laundry balls or specialized anti-tangle devices work
Real laundry accessories are designed with:
- Proper weight distribution
- Safe materials
- Tested movement patterns
A random bottle is not.
What actually works for the problems people are trying to solve
For pet hair:
- Lint rollers or reusable pet hair removers
- Washing with vinegar rinse or dryer sheets
For tangling:
- Don’t overload the machine
- Wash similar fabrics together
- Use mesh laundry bags
For better cleaning:
- Correct detergent amount (more is not better)
- Proper cycle selection
- Occasional drum cleaning cycle
