PET HAIR + LAUNDRY
What do I need for pet hair in the laundry?

Start dry
Hair clings more stubbornly once fabric is wet. Shake items outside, brush or lint-roll the worst areas, and avoid stuffing the washer so full that fabric cannot move.
Then maintain the machines
Clean the dryer lint screen every load. Check the washer gasket, filter, or drain-cleaning instructions in the owner’s manual if pet hair builds up. Different machines provide different maintenance access.
For pet bedding
Vacuum or shake it first. Washing a blanket that is carrying a visible layer of hair simply transfers a lot of that hair into the machine.
Use the dryer strategically
For dryer-safe items, a short tumble before washing can loosen hair so some of it reaches the lint filter instead of the washer. Use the fabric and appliance settings appropriate for the item. Clean the lint screen afterward.
Do not overload the washer
Fabric needs room to move so water and detergent can circulate. Stuffing the drum tightly can trap hair in folds and reduce rinsing. Split a very hairy load rather than trying to process every pet blanket at once.
Handle the source too
Regular brushing, washable pet covers, and vacuuming the pet’s favorite sleeping areas reduce the amount of loose hair that reaches clothing and bedding. Laundry tools are easier to use when they are not fighting the full shedding load every week.
Quick questions
Do laundry pet-hair gadgets work?
Some can help, but removing loose hair before washing and keeping filters clean usually matters more than any single gadget.
Can pet hair damage a washing machine?
Heavy buildup can collect in gaskets, filters, and drains, so removing loose hair first and following machine-cleaning instructions is a sensible routine.
