The 10 Best Dog Tear Stain Removers:
Dog tear stain removers are not going to work like bleach, and you wouldn't want to use that caustic a chemical around your pet's eyes, anyway. Instead, a dog tear stain remover is going to clear away the dirt and gunk that has built up recently so that any future staining will stop.
To remove stubborn tear stains, use a soft, lint-free cloth to gently work a small amount of coconut oil into the stain. Use a white or light-colored cloth so you can see the red or brown matter collecting on the cloth.
The boric acid will oxidize and lighten the stains caused by the iron in your pup's tears. Lemon juice is another alternative cleanser—use a cloth dipped in a mixture with warm water to gently wipe the affected area around your dog's eyes, doing this once a day to lighten the stains.
Bichon fur responds especially well to baking soda pastes to clean tear stains. Add a few drops of water to baking soda until you have a thick paste. Apply the paste and let it sit for an hour or so.
Hydrogen Peroxide: To remove tear stains, soak a cotton pad in a water-diluted hydrogen peroxide mixture (one part hydrogen peroxide with 10 parts water) and use it to carefully clean the stained area. Be careful not to get any of the hydrogen peroxide in your dog's eye.
Using coconut water to treat tear stains is easy. Rub the coconut oil into each stain on his fur until they disappear (usually a couple of days). NEVER use make-up remover or bleach to get rid of tear stains.
White Vinegar/Apple Cider Vinegar: Add a teaspoon of distilled white vinegar or apple cider vinegar to your dog's water daily to increase the acidity of your dog's body pH. Not only will it take care of tear stains, the alkalinity of your dog's body will help to prevent bacteria or yeast infections from recurring.
Most of the discoloration of the fur isn't permanent, although stains that have been neglected for a long time will need to grow out and be trimmed before disappearing completely.
