Put an Empty Plastic Bottle in the Washing Machine: The Simple Trick Most People Don’t Know

Is Your Laundry Getting Tangled and Not Cleaning Properly?

One of the most common and frustrating problems in laundry is clothes twisting and tangling together during the wash cycle. This issue especially affects larger items such as bedsheets, towels, long pants, and hoodies. When fabrics wrap around each other, it can cause several problems that go beyond mere inconvenience.

Twisted clothes often don’t get washed evenly. Dirt and detergent may not reach all fabric areas, leaving some spots still dirty after washing. Tangled laundry also tends to come out heavily wrinkled, which can increase the time and effort needed for ironing or steaming. Additionally, clothes that remain twisted take longer to dry because air circulation is blocked when fabrics are bunched together.

These problems can add up in both time and cost. If laundry is consistently coming out wrinkled or partially dirty, you might find yourself re-washing loads or resorting to professional laundry services, which can cost $10 to $20 per load depending on your location. Moreover, repeated rewashing increases wear on fabrics and energy bills.

How to Identify If Tangling Is Your Issue

Before trying any solutions, check your laundry loads for signs of twisting. After a wash, if you notice:

  • Large clumps of fabric stuck together
  • Uneven cleaning with dirty patches
  • Excessive wrinkles that don’t smooth out easily
  • Long drying times beyond what’s typical for your washer and dryer

then fabric tangling is likely the root cause of your laundry woes.

What Happens When You Put an Empty Plastic Bottle in the Washing Machine?

A simple but increasingly popular method to reduce tangling involves placing one or two empty plastic bottles inside the washing machine drum along with your clothes. The bottles should be completely empty, clean, and tightly capped to prevent water from entering.

During the wash cycle, these bottles move independently inside the drum, acting as physical separators between clothes. This movement keeps fabrics from wrapping tightly around each other.

Contrary to some viral claims about improving water circulation or agitation, the main mechanism is straightforward: the bottles create physical gaps that reduce fabric contact and tangling. This interruption in how clothes normally twist together helps the detergent and water reach fabric surfaces more evenly.

However, caution is needed. Using too many bottles or fragile containers can unbalance the washer drum, potentially leading to mechanical issues. Glass bottles are unsafe and should never be used. One or two sturdy plastic bottles are enough for a typical household load.

Professional appliance repair for drum imbalances or damage can easily cost $150 or more, so it’s essential to avoid overloading the machine with hard objects.

Before trying this trick, assess your washer’s manual for any warnings about foreign objects inside the drum. If in doubt, consult a technician to avoid voiding warranties.

This simple plastic bottle method could be the key to smoother, cleaner laundry and fewer wrinkles—without extra expense or specialized products.
