The bottle can also help water and detergent circulate more evenly through a large load. Supporters of the trick claim that this leaves clothes less wrinkled and makes them easier to dry and iron.
Use only a small, lightweight bottle with its label removed and no sharp edges. Make sure it is completely empty, and avoid thick or rigid bottles that could interfere with the spin cycle or damage the machine.
Although this is a simple, inexpensive household trick, washing-machine manufacturers do not generally recommend adding loose objects to the drum. Stop using it if the bottle becomes damaged or causes unusual noise, and follow your machine’s official instructions.
