How to Naturally Remove Dog Tear Stains

No, skip baking soda for dog tear stains, especially anywhere close to the eye. A baking-soda paste can leave alkaline grit in the fur, can be rubbed into the eye, and will not stop the tears that caused the stain. The safest natural approach is to gently remove fresh moisture with water, dry the fur well, and address any eye irritation or excessive tearing.

Why Dog Tear Stains Form

Dog tear stains are usually rusty red, reddish-brown, or dark marks below the inner corners of the eyes. They are especially noticeable on white and light-colored coats.

The color comes from porphyrins, iron-containing compounds released as the body breaks down red blood cells. Porphyrins leave the body in several fluids, including tears; when tears repeatedly wet the same facial hair, the pigment can discolor it.

Some dogs tear more because of their facial structure, shallow eye sockets, skin folds, hair rubbing the eye, or drainage problems. Eye irritation, allergies, dry eye, infection, or a blocked tear duct can also increase tearing.

Cleaning can remove fresh moisture and crust, but it cannot safely turn already stained hair white again.

Baking soda is sometimes suggested because it is mildly abrasive and alkaline. Those qualities are exactly why it is a poor choice around an eye: it can irritate delicate skin, leave residue, and create a bigger problem if any paste gets into the eye.

How to Clean Dog Tear Stains Without Baking Soda

Use this guide to choose the safest next step before you clean your dog’s face.

What You See	Best Next Step	Why
Mild rust-colored staining, with a comfortable-looking eye	Use a damp cloth and dry the fur	This removes fresh tears and surface debris without putting a paste near the eye.
Sticky tears or a small amount of softened crust on the hair	Soften it with water, wipe outward, then dry	Pulling at dry debris can tug facial hair and irritate the skin.
Hair poking the eye, mats near the inner corner, or stain packed into facial folds	Ask a groomer or veterinarian for help	Scissors and combs are risky close to an eye.
Redness, squinting, swelling, discharge, pain, or sudden heavy tearing	Stop home cleaning and contact a veterinarian	Tear staining may be secondary to an eye problem that needs treatment.

Step 1: Check the Eye Before Cleaning

Look at both eyes in good light before touching the fur.
Make sure your dog is not squinting, holding an eye closed, pawing at the face, or resisting because of pain.
Check for redness, swelling, cloudiness, a visible injury, or thick yellow, green, bloody, or foul-smelling discharge.
If you see any of these signs, do not try to scrub away the stain. Arrange veterinary care instead.

A quiet, comfortable dog with clear eyes and ordinary watery tears is usually appropriate for gentle coat cleaning. If your dog is anxious or keeps moving, pause rather than trying to hold the face still and work close to the eye.

Step 2: Soften the Stained Fur With Plain Water

Wash your hands.
Wet a clean, soft washcloth with lukewarm water and wring it out well. It should be damp rather than dripping.
Support your dog’s head gently if needed, keeping your fingers away from the eyeball.
Hold the damp cloth against the stained hair below the eye just long enough to soften dried tears or crust.
Do not pour water over the face, spray the area, or press a cloth directly on the eye.

Plain water is a good first choice because the goal is to lift tear residue from the coat, not to bleach the fur or change the skin’s chemistry. Do not substitute baking soda, vinegar, hydrogen peroxide, cornstarch paste, essential oils, or household cleaning products.

Step 3: Wipe Away From the Eye

Starting at the inner corner beneath the eye, wipe gently outward and downward along the direction the fur grows.
Use a clean portion of the cloth for each pass so you do not rub loosened debris back into the coat.
Use a separate clean section of cloth for each eye.
Stop if your dog flinches, struggles, or if the skin looks sore.

Do not scrub. Repeated rubbing can make the skin irritated and may cause more tearing, which creates more staining.

Step 4: Dry the Face and Finish the Grooming

Pat the cleaned fur dry with a clean towel or dry area of the washcloth.
Separate damp hairs gently with your fingers so moisture is not trapped in a facial fold.
Put the cloth in the laundry and wash your hands again.
If the fur remains rust-colored after it is clean and dry, leave it alone rather than applying a whitening paste. The discoloration is in the hair itself and will fade only as that hair is trimmed away or replaced by new growth.

If long hair repeatedly reaches the eye or holds moisture against the skin, have a groomer trim it. Avoid cutting hair around your dog’s eyes yourself unless you are already confident with safe facial grooming and your dog stays completely still.

When Tear Stains Need Veterinary Attention

Tear stains are often cosmetic, but excessive tearing is not always a grooming issue. A dog may produce more tears because something is irritating the eye or because tears are not draining normally.

Contact a veterinarian if you notice:

Sudden onset of tearing in a dog that normally has dry facial fur
Squinting, blinking hard, rubbing the eye, or sensitivity to light
Red, swollen, cloudy, or injured-looking eyes
Thick discharge or an unpleasant odor
Staining that is getting worse despite gentle cleaning
Hair, eyelashes, or a skin fold constantly touching the eye
A dark crust that returns quickly and seems painful to remove

A veterinarian can look for causes such as dry eye, allergies, infection, eyelid problems, abnormal eyelashes, or tear-duct obstruction. Treating the cause matters more than repeatedly cleaning the coat.

Removing Set Rust Stains and Black Crust

Old rust-colored hair is not the same thing as active dirt.

For established stains, the practical options are limited:

Keep fresh tears cleaned off so the stain does not spread farther down the hair.
Keep the facial fur dry after cleaning.
Let stained hair grow out naturally.
Have a groomer carefully remove stained ends when it can be done safely away from the eye.

Black crust deserves a closer look. It may be dried tears or mucus mixed with fur and environmental debris, especially in facial folds. A small amount that softens easily with water can be wiped away gently. Recurrent, thick, sticky, smelly, bloody, or painful crust should be checked by a veterinarian rather than treated as a cosmetic stain.

Preventing New Dog Tear Stains

Prevention is mostly about managing moisture before it sits on the coat.

Wipe away tears when you notice the fur is wet.
Dry the area after cleaning instead of leaving the face damp.
Keep long facial hair from touching the eye; use a professional groomer if needed.
Keep the area around skin folds clean and dry.
Watch for seasonal changes, new foods, environmental irritants, or grooming products that coincide with increased tearing.
Use only products specifically intended for pets and with eye-area use stated on their packaging.

Avoid adding vinegar to drinking water or giving supplements solely to change tear stains without veterinary guidance. Tear staining can have several causes, and changing a dog’s water or diet is not a reliable substitute for identifying an eye problem.

Frequently Asked Questions

Can I use baking soda on my dog’s eye tear stains?

No. Do not use baking soda paste on or near your dog’s eyes, even if you intend to apply it only to the fur. It can leave irritating residue, may be transferred into the eye during blinking or rubbing, and cannot solve the underlying reason your dog is tearing.

How long does it take for dog tear stains to go away?

There is no reliable fixed timeline: wiping removes fresh tears and surface residue right away, but stained hair stays discolored until it is trimmed away, shed, or replaced by new growth. If your dog continues to tear heavily, new staining can form before the old hair grows out.

How do I remove tear stains with boric acid and baking soda?

Do not make or apply a boric-acid-and-baking-soda mixture to your dog’s face. Household ingredients are not a safe substitute for a veterinary eye-area product, and neither ingredient should get into the eye. For mild staining, use a damp cloth and dry the fur; for persistent tearing, ask a veterinarian what is appropriate for your dog.

How can I treat my dog’s fur that is turning rust color?

Treat the moisture source first by gently wiping and drying the fur whenever tears collect. The rust color is commonly porphyrin staining in the hair, so set discoloration generally needs to grow out or be safely trimmed by a groomer rather than scrubbed or bleached away.

How do I get rid of black crust around my dog’s eyes?

Soften a small amount of dry crust with a lukewarm damp cloth, wipe outward from the eye, and dry the fur afterward. If the crust is thick, recurrent, smelly, bloody, painful, or paired with redness, squinting, or discharge, contact a veterinarian rather than continuing home treatment.

How can I clean dog tear stains naturally at home?

At home, clean the fur below your dog’s eye with a warm, damp washcloth and dry the face afterward. Wipe outward, away from the eye, rather than putting a cleanser in the eye.

Does hydrogen peroxide remove dog tear stains?

Do not get hydrogen peroxide in your dog’s eyes, as it can be irritating. For mild staining, use a warm, damp cloth instead and wipe away from the eye.
