Why are people putting a ball of aluminium foil in the washing machine? The surprising reason behind the viral laundry hack

Aluminium foils have many usage at home but some not so common usages have gone viral on the internet. One such case is keeping a simple ball of aluminium foil in the washing machine. Many claim that it helps reduce static cling on clothes and makes fabrics feel fresher without relying as much on dryer sheets.

But does it actually work? Here's what you need to know.

What is the aluminium foil laundry hack?

The trick is straightforward. Tear off a sheet of aluminium foil, crumple it tightly into a smooth ball about the size of a tennis ball, and place it in the washing machine or dryer along with your clothes.


Many people use two or three foil balls for larger loads. The balls can typically be reused for several months before they need replacing, provided they remain tightly packed and do not start breaking apart.

Why do people use it?

The main reason is to reduce static electricity.

During drying, fabrics rub against one another, creating static charges that cause clothes to cling together. Aluminium is a conductive metal, meaning it can help discharge some of the static electricity that builds up during the laundry cycle.

Many users say this leaves clothes with less static cling, particularly synthetic fabrics such as polyester, fleece and nylon.

Does it replace fabric softener?

Not entirely.

While aluminium foil may help reduce static, it does not soften fabrics, add fragrance or remove wrinkles the way fabric softeners or dryer sheets are designed to do.

If your goal is softer towels or scented laundry, you'll still need products specifically made for those purposes.

Is it safe to use?

Generally, yes—with a few precautions.

Use only tightly crumpled foil balls with no sharp edges that could snag delicate fabrics. Replace them if they begin to tear or unravel.

Avoid using foil balls if your washing machine or dryer manufacturer specifically advises against placing metal objects inside the appliance. Checking your appliance manual is always a good idea.

Does it work in a washing machine or only in a dryer?

The hack is more commonly recommended for dryers because static electricity mainly develops during the drying process.

Using foil balls in the washing machine is unlikely to provide significant benefits, as clothes are surrounded by water, which already conducts electricity and prevents static buildup.

The bottom line

Putting a ball of aluminium foil in the dryer may help reduce static cling on clothes, especially those made from synthetic materials. It's an inexpensive, reusable alternative that some households find useful.

However, it is not a replacement for fabric softener, and it won't make clothes cleaner, softer or more fragrant. If you decide to try the hack, use tightly packed foil balls, inspect them regularly for damage, and follow your appliance manufacturer's recommendations.
