Common questions
Hoof spray & clay FAQ
What is The Blue Spray® ?
The Blue Spray is a specialized prevention and treatment product designed to protect horses from thrush—a common fungal infection in hooves. It combines the natural power of vinegar and copper sulfate to help maintain healthy hooves and prevent thrush.
What are the active ingredients in The Blue Spray?
The Blue Spray contains two key ingredients: vinegar and copper sulfate. These ingredients are known for their antifungal and antibacterial properties, which help combat the pathogens that cause thrush in horse hooves.
How does The Blue Spray work?
Vinegar acts as a mild acid, helping to disinfect and reduce the growth of fungi, while copper sulfate has strong antimicrobial properties that target both bacteria and fungi responsible for thrush. Together, they work to prevent and treat thrush while promoting overall hoof health.
Is The Blue Spray harsh?
No, The Blue Spray is not harsh when used as directed. The formulation is balanced to be effective without causing irritation to your horse’s hooves or skin. However, as with any product, it’s important to follow the recommended usage guidelines to ensure the best results and avoid overuse.
How often should I use The Blue Spray?
For active thrush: Apply The Blue Spray daily until the condition improves.
For prevention: Apply The Blue Spray 2-3 times per week to help maintain healthy hooves and prevent thrush from developing.
Can I use The Blue Spray on all horses?
Yes, The Blue Spray is safe for use on all horses. However, as with any new product, we recommend doing a small patch test first to ensure there are no adverse reactions, especially for sensitive horses.
Is The Blue Spray safe to use in wet conditions or after rain?
Yes, The Blue Spray can be applied even in damp or wet conditions, although applying it to dry hooves is generally more effective. For best results, ensure the hooves are as clean and dry as possible before application.
Can I use The Blue Spray on hooves with open wounds?
It’s best to avoid applying The Blue Spray directly to open, raw wounds or cuts. If your horse’s hooves have open sores, we recommend consulting your veterinarian for advice on appropriate treatment. The Blue Spray is safe to use on healthy, intact hooves.
How should I store The Blue Spray?
Store The Blue Spray in a cool, dry place, away from direct sunlight, and out of reach of children and animals. Make sure the cap is tightly closed to prevent leakage and contamination.
