What is Zep?

Zep is a well-established brand specializing in a wide range of cleaning and maintenance solutions for both residential and commercial use. Their product range includes solutions such as all-purpose cleaners and degreasers to specialized formulas targeting specific stains and contaminants.

Among their lineup, the Zep Mold Stain and Mildew Stain Remover is a notable product designed to combat mold and mildew stains effectively. It is formulated with powerful chemicals, including sodium hypochlorite (bleach), to remove mold and mildew stains from various surfaces.

Does Zep kill black mold?

The effectiveness of Zep Mold Remover in killing black mold depends on various factors. While it is designed to remove mold and mildew stains, it may not be explicitly formulated to target the specific strain of black mold. As with any mold removal product, it is essential to follow the manufacturer’s instructions and take necessary precautions when using Zep Mold Remover on black mold-infested areas.

Is Zep toxic?

Yes, it contains sodium hypochlorite, which is a powerful bleach and disinfectant. And although a very effective product, it can also cause skin and eye irritation. So it is essential to handle it with care and take the following safety precautions:

Use Personal Protective Equipment: Always wear appropriate personal protective equipment, such as gloves and safety goggles, when handling Zep Mold Remover. This helps protect your skin and eyes from potential contact with the product.

Ventilation: Open windows or use fans to allow fresh air to circulate in the area being treated. This helps minimize inhalation of fumes and reduces exposure to the product’s chemical vapors.

Never Mix: Never mix Zep Mold Remover with other cleaning agents or chemicals, especially ammonia or acids. Mixing different chemicals can produce toxic fumes that can be harmful to your health.

Test First: Before using the product on a large area, conduct a small patch test in an inconspicuous area first. This helps verify that the product is compatible with the surface and does not cause any damage.

Keep Out of Reach of Children and Pets: Store Zep Mold Remover in a secure location, out of the reach of children and pets. Ingestion of the product can be harmful, and accidental spills or leaks must be cleaned up promptly.

If you prefer to use eco-friendly and non-toxic products, there are alternative mold removal options available. Consider using natural remedies such as vinegar, hydrogen peroxide, or tea tree oil. These substances have natural antifungal properties and can be effective in killing mold on surfaces.

How do you use Zep Mold Stain Remover?

It’s important to note that this product is specifically formulated to remove mold stains and not to kill mold. Here’s a step-by-step guide on how to use Zep Mold Stain Remover:

Preparation: Before using Zep Mold Stain Remover, open windows or use a fan. Also put on the personal protective equipment, such as gloves and safety goggles, to protect your skin and eyes.

Testing: Test the product in a small, inconspicuous area first to ensure compatibility with the surface you intend on cleaning.

Application: Spray or apply the Zep Mold Stain Remover directly onto the mold stained areas.

Let it Sit: Allow the product to sit on the stains for the recommended dwell time specified on the product label. This allows the active ingredients to penetrate and break down the stains.

Agitation: For stubborn mold stains, gently scrub the surface with a brush or sponge to help the product penetrate deeper.

Clean Up: After the dwell time has elapsed, wipe away the mold and the product using a clean, damp cloth or sponge. Then rinse the treated area thoroughly with water and allow it to dry completely.


In conclusion, Zep Mold Stain Remover effectively removes mold stains, but its efficacy against black mold may vary. Use with caution as it contains sodium hypochlorite, which can irritate the skin and eyes. Consider eco-friendly alternatives and prioritize safety for a cleaner living space.
