Why Is There So Much Lint in My Dryer?

Dryer lint is the glitter of the laundry world: It gets everywhere, and you can never get rid of it all. It's part of normal wear and tear on clothes and linens as they age. However, if you're finding a lot of lint in your dryer, it could signal a problem such as a clogged vent or mechanical issues.

Why Does My Dryer Produce So Much Lint?

Lint is a natural byproduct of washing and drying clothes, towels and linens. However, the amount of lint produced can vary depending on your dryer, the items you're washing and the cycle you're using. If the amount of lint in your dryer seems excessive, there could be several possible reasons:

• Drying new items. New clothes and linens (particularly towels and fleece-lined sweatshirts) often have loose fibers and may shed more, so if you're washing items for the first time, expect more lint than usual.

• Drying old items. As clothing ages, it begins to break down, which can cause excessive shedding, so if you're washing old items, expect to find a lot of lint.

• Unemptied pockets. Tissues, napkins and other paper products that find their way into the laundry can break down, leading to excess lint.

• Overdrying. Drying your clothes for too long, particularly on a high-heat setting, can take a toll on fabrics, breaking them down more quickly and creating excess lint.

• Vent clogs. If clothes come out of the dryer covered in lint or lint accumulates behind your unit, the vent may be clogged. Clogs can prevent your dryer from properly venting excess lint outside.

• Mechanical issues. A damaged lint trap or worn drum seals can hinder a dryer's airflow, causing a buildup of lint inside the unit.

Wait ... What Is Lint in the First Place?

Each time you wear clothes or use a towel, you create friction that loosens fibers. When these items tumble in the dryer, those tiny pieces of fabric, yarn and thread pull free. These microfibers form the fuzz we commonly refer to as lint.

Wool, cotton and linen are common components of lint. However, this dryer fuzz can also contain:

• Dust

• Hair

• Pollen

• Pet fur

• Dead skin cells

• Plant fibers

• Debris such as tissue fragments

Is Excessive Dryer Lint Bad?

In small quantities, lint is generally harmless. However, dryer lint buildup can cause:

• Fire hazards. Lint is highly flammable. If accumulated lint in a dryer trap or vent overheats, it can start a fire.

• Longer drying times. Excess lint can block your dryer's airflow, reducing its effectiveness. This loss of efficiency results in longer drying times and higher energy bills.

• Dryer damage. When lint builds up and blocks vents, your dryer has to work harder, which can cause overheating. Continuous overheating can wear down the motor or damage the heating element, resulting in costly repairs.

• Damaged clothing. If the lint trap gets clogged, debris can break free and damage your clothes, causing them to wear out faster.

• Reduced air quality. Excess dryer lint can escape into the air, reducing your home's air quality. Poor indoor air quality can aggravate respiratory illnesses in those who have asthma or allergies.

How Can I Reduce the Amount of Lint?

Although you can't eliminate lint, you can reduce buildup in your dryer by following these best practices:

• Empty your dryer's lint trap every time you run the dryer. Pull out the lint screen, roll the lint off with your fingers and dispose of it in a sealed trash can. Use your vacuum's brush attachment to remove stubborn lint.

• Use the gentle cycle when washing clothes. Using cold water and laundering clothes on the delicate cycle can reduce agitation, creating less friction so your clothes won't break down as easily.

• Dry your clothes on a low-heat or air-dry setting. Lower heat means less wear and tear on your clothing, which can lead to less lint.

• Switch to smooth ducting. It's less likely to snag lint, so there's less buildup over time.

It's also important to practice good appliance maintenance. Every 6 months, deep-clean your lint trap using a mixture of mild liquid detergent and water. Scrub away any residue with a nylon brush. Then, using your vacuum's crevice attachment or a small brush, clean out the slot beneath the trap. At least once a year, you should also clean out your dryer's vents and ductwork using a specially designed long-handled brush.

Inspect the exterior vents regularly for blockages due to dirt, lint and pests. For tough dryer lint removal tasks, call a pro.
