Putting an empty plastic bottle in the washing machine is actually a little household trick—but it depends on how and why you’re using it.
🧺 What it’s used for
- Improves agitation: The bottle bounces around and helps move clothes more, similar to laundry balls
- Can help remove lint/hair: Especially useful if you have pets
- May slightly improve cleaning efficiency for bulky items like blankets
⚠️ Important precautions
- Use a small, sturdy bottle (like a soda bottle) with the cap tightly closed
- Make sure it’s completely empty (no liquid inside)
- Avoid thin or flimsy plastic—it can crush or break
- Don’t overload the machine; the bottle needs space to move
- Not ideal for delicate clothes (it can be rough)
❌ When NOT to do it
- In front-load washers with delicate cycles
- With fragile fabrics like silk or lace
- If your machine manufacturer advises against foreign objects
👍 Better alternatives
- Laundry balls (designed for this purpose)
- Tennis balls (commonly used for towels or duvets in dryers)
- Proper lint filters or pet hair removers
✔️ Bottom line: It can work in some cases, but it’s not essential—and using proper laundry tools is safer and more reliable.
