Pet hair does not wash out. This surprises people every time, and it is the reason a load can come out of the machine cleaner than it went in and still be covered.
Water does not dissolve hair. A wash cycle suspends it, moves it around, and redeposits most of it onto whatever else is in the drum. Then it goes into the dryer, where some of it finally leaves and the rest gets pressed into fabric by heat.
The whole job is therefore mechanical, and almost all of it happens before the machine.
Get it off before it goes in
This is ninety percent of the solution and it takes two minutes.
Shake everything outdoors. Hard, and turn pockets and cuffs out.
Use a rubber glove. Put on a dry dishwashing glove and run your hand firmly over the fabric. Static and friction pull hair into clumps you can lift off. This works better than a lint roller and it costs nothing.
A slightly damp rubber glove or a damp sponge works even better on upholstery and heavy fabric.
A pumice stone or a rubber pet brush works the same way on blankets and pet bedding, which hold far more hair than clothing does.
Vacuum pet beds and heavy blankets before washing. It seems excessive and it is the difference between one wash and three.
Run a dryer cycle first. Twenty minutes on air fluff or low heat, with no water, before washing. The tumbling loosens hair and the lint trap catches it. This is the single most effective machine step, and it is the one almost nobody knows about. Clean the lint screen immediately afterward, because it will be full.
Then the wash
Wash pet items completely separately. Never with clothing, never with bedding.
Do not overload. Hair needs free water to be carried away, and a packed drum means it has nowhere to go but back onto fabric.
Half a cup of white vinegar in the rinse. It relaxes fibers so they release hair, and it cuts the static that makes hair cling. This is the one additive worth using.
Skip the fabric softener. It coats fibers, and coated fibers grab hair rather than releasing it. Vinegar does the anti-static job without the film.
Extra rinse, which is where suspended hair actually leaves.
Clean the machine afterward. Wipe the drum, pull back the door seal and clear the fold, and check the drain pump filter. Hair collects in all three, and in the filter it eventually causes drainage problems. If pet laundry is a regular thing in your house, check that filter every couple of months rather than once a year.
Drying
Dry pet items alone. Clean the lint screen before, halfway through, and after. A screen that fills mid-cycle stops catching, and everything after that point stays in the load.
Wool dryer balls help by separating fabric so hair can escape rather than staying pressed between layers.
Then vacuum out the dryer drum before your next normal load. Hair sticks to the inside and transfers.
Dander, which is the part people care about more
Hair is a nuisance. Dander is what actually triggers allergies, and it behaves differently.
Dander is microscopic skin flakes, and unlike hair it does wash out, because it is small enough to suspend in water and leave with it. The allergen itself is a protein, and the practical consequences follow from that.
Wash in hot water where the fabric allows. Heat is more effective on protein allergens than warm or cold.
Wash pet bedding weekly if anyone in the house has allergies. This does more than any air purifier.
Wash your own bedding weekly too, in hot, particularly if the animal sleeps on the bed. Most of the dander exposure in an allergic household happens during sleep.
An extra rinse matters because it is what carries suspended protein away rather than leaving it in the fabric.
Do not dry-brush a pet indoors. That puts dander into the air of the room you are standing in. Outside, or in a room you can ventilate.
The specific problem items
Pet beds. Most have a removable cover, which is the washable part. Check whether the insert can be washed, because many cannot and will not dry through. Vacuum the insert instead and replace it periodically.
Blankets the dog sleeps on. These hold more hair than anything else in the house. Vacuum, then dryer cycle first, then wash alone.
Car seat covers. Same treatment, and they are usually too large for a household machine to tumble.
Anything with a rubber or vinyl backing, including many pet mats, should never see a hot dryer. The backing degrades and can ignite.
Accidents. Enzyme cleaner rather than ordinary detergent. Enzymes break down the proteins that cause the smell, and ordinary detergent leaves them behind, which is why a spot keeps smelling to the animal even after it looks clean. Never use ammonia-based cleaners, since ammonia smells like urine to a pet and encourages repeat visits to the same spot.
Where the machine size changes things
Pet bedding is the clearest case in this whole theme. A dog bed cover, a set of blankets, or a car seat cover packed into a household drum cannot tumble, so the hair never gets free of the fabric and the water never moves through it.
The machines at our self-service laundry on West 71st Street have the drum volume for a full pet bed to move freely and considerably more water per cycle, which is exactly what suspended hair and dander need in order to leave rather than resettle.
The other reason is your own machine. Every load of pet laundry leaves hair in the drum, the seal, and the filter, and it transfers to the next load. Running it here keeps it out of the machine your sheets go through. Our machines and the store are cleaned daily, which is the difference between a shared machine and a neglected one.
Our wash-dry-fold service covers everyday laundry as well.
The short version
Hair does not dissolve, so removing it is mechanical and it happens before the wash. Shake items outdoors, go over them with a dry rubber glove, and run a twenty minute no-heat dryer cycle first, which is the step nobody knows about. Wash pet items alone, never overloaded, with vinegar in the rinse and no fabric softener. Dander is different: it does wash out, it is what triggers allergies, and it wants hot water and weekly washing of both the pet’s bedding and yours. Clear your drain pump filter every couple of months if pet laundry is routine.
