Seemingly harmless items that can damage your washing machine

Most people know to check the label and color sort before loading their clothes into the washing machine , but there are some everyday items that can cause serious damage if not washed properly. These items can not only ruin your clothes, but can also damage your washing machine, leading to expensive repairs and even shortening the life of your appliance. Here are some things that can do more harm than good to your washing machine .

Rubber

Rubber can cause serious problems for your washing machine. In fact, it is difficult to clean this material. Items such as rubber mats, shoes, or cushions can clog filters and pumps. This can prevent drainage and potentially damage the machine. To avoid these problems, it is best to hand wash rubber items if possible or use a commercial washing machine.

Fabric softener

While fabric softeners make your clothes smell fresh, they can cause long-term damage to your washing machine. Fabric softeners can build up in your washing machine's lines and collect in the dispenser, leading to clogs over time. Instead, consider using fabric softeners with a few drops of essential oils for a natural scent.

Too much detergent

This may sound strange, but using more detergent than necessary doesn't always mean "cleaner" clothes. In fact, too much detergent can damage your washing machine by clogging sensors and preventing water from draining properly. It can also leave a musty smell on clothes and excessive suds in the machine. Choose a mild detergent and use the recommended amount for best results.

Pet hair

Clothes covered in pet hair can cause problems for your washing machine. Pet hair clumps together and can clog the drain pump, straining your washing machine and plumbing. So if you have a pet, always shake the hair off your clothes before putting them in the washing machine.

Large items

Oversized items such as comforters, rugs, or blankets can become too heavy when wet, straining the machine's drum and motor. Because of limited mobility, these items may not be cleaned properly. It is best to wash them in a commercial washing machine or take them to a dry cleaner.

Memory foam pillow

While memory foam pillows are washable, putting them in the washing machine can deform the pillow and affect its support. Like other bulky items, memory foam pillows may not be completely cleanable due to the limited movement in a regular washing machine. For best results, consider washing your pillow in a commercial washing machine, taking it to a dry cleaner, or simply hand washing it.

Wool and cashmere material

Delicate fabrics such as wool and cashmere can be damaged or lose their softness when machine washed. To maintain their quality, hand wash these items in cold water or use a mesh bag in the washing machine on the gentle cycle.

Keys and jewelry

You accidentally leave your keys or jewelry in your pocket and they get washed. Unfortunately, this mistake can cause significant damage to the drum and internal components of your washing machine. Be sure to check your pockets before putting your clothes in the washing machine.

Coins

Just like keys, coins can get into your washing machine and cause damage by clogging filters and pumps. Always check your pockets carefully to avoid these small but costly problems.

Waterproof gear

Although some waterproof items may be labeled machine washable, hand washing is safer. Items such as ski pants, waterproof mattress pads, shower curtains, or sleeping bags can retain water, causing an imbalance during the spin cycle and potentially damaging the machine.

Zipper open

Unzipped zippers can catch on other clothing and scratch the inside of the machine. Always zip up your clothes before washing to protect your clothes and your washing machine.

Decoration

Garments with beads, sequins or lace can be easily damaged in the washing machine. These delicate materials can get caught in the machine's mechanisms, so it's best to hand wash them or use a mesh bag to protect them.
