How to Remove Pet Hair from Your Washing Machine

Last Updated: March 18, 2026 Reading Time: 5 minutes

Quick Answer

Pet hair in the washing machine clings to clothes and coats the drum. Before washing pet hair-covered items, run a dryer sheet over them or use a lint roller. In the washer, add 1/2 cup white vinegar to the rinse cycle to release hair. After washing, clean the washer's lint trap and run an empty hot cycle to flush out remaining hair.

Why Pet Hair Survives Washing

Water doesn't dissolve pet hair. Instead, wet hair mats together and sticks to fabric even more aggressively. The washing machine's agitation can embed hair deeper into clothing fibers rather than removing it.

Additionally, pet hair is lighter than water. When the spin cycle ends, hair that was suspended in water resettles on clothes as they stop moving.

Prevention: Before the Wash

Remove Hair First

Lint roller: Roll pet bedding, blankets, and clothes before washing. This removes 70%+ of loose hair before water ever touches the fabric.

Dryer sheet swipe: Rub a fabric softener sheet over items. The anti-static coating helps hair release in the wash.

Rubber glove method: Put on a damp rubber glove and wipe down items. Hair clings to the glove.

Separate Loads

Wash pet items separately from human clothing. This prevents hair transfer and lets you use stronger cleaning methods on pet loads.

During the Wash

Add Vinegar to Rinse Cycle

1/2 cup white vinegar in the fabric softener dispenser:

• Reduces static cling
• Helps release hair from fabric
• Acts as a natural fabric softener
• No, your clothes won't smell like vinegar (the smell dissipates during drying)

Use Less Detergent

Excess detergent creates suds that trap hair in fabric. Use the recommended amount, not more.

Choose the Right Cycle

• Water level: High (more water = more space for hair to float away from clothes)
• Agitation: Standard or heavy (needed to dislodge hair)
• Temperature: Warm or hot (hot water helps release oils holding hair)

After the Wash: The Transfer Problem

The biggest mistake: Moving wet, hair-covered clothes directly to the dryer.

Wet hair mats and bakes onto fabric in the dryer's heat. Before drying:

1. Shake each item vigorously outdoors or over a trash can 2. Use a lint roller on still-damp items 3. Only then transfer to dryer

In the Dryer

Dryer sheets: Use them. They reduce static and help hair release into the lint trap.

Lint trap: Clean it before AND after drying pet items. A full lint trap reduces airflow and trapping efficiency.

Wool dryer balls: Optional but helpful. They create separation between items and help knock loose hair free.

Cleaning Your Washing Machine

Pet hair accumulates in washers over time, causing odors and redepositing on future loads.

Monthly Maintenance

1. Remove and clean the lint trap (if your washer has one — many modern ones don't) 2. Wipe the drum and door seal with a damp cloth 3. Run an empty hot cycle with 2 cups white vinegar to dissolve hair and residue

Deep Clean (Every 3 Months)

1. Run empty hot cycle with washing machine cleaner or 2 cups vinegar 2. Scrub the detergent dispenser 3. Check and clean the drain pump filter (usually front bottom corner) 4. Wipe down the rubber door seal thoroughly

FAQ

Can I use a washing machine cleaner tablet for pet hair? Yes, but vinegar works just as well and costs less. The goal is dissolving accumulated residue that traps hair.

Why is there still hair on clothes after washing? You probably skipped the pre-wash hair removal. Washing doesn't remove hair — it just moves it around. You must remove loose hair before washing.

Is pet hair bad for my washing machine? Over time, yes. Hair can clog drains, coat sensors, and create odor-causing buildup. Regular maintenance prevents problems.

Bottom Line

Washing machines don't remove pet hair — they just redistribute it. The solution is multi-step: remove hair before washing, use vinegar in the rinse, shake clothes before drying, and clean your machine monthly. Do this and your clothes will actually come out clean.
