How to Eliminate Odor Permanently. Backed by Science. Trusted by Professionals.
How do I permanently remove cat urine odor from carpet?
Urine permeates the surface into the padding and subfloor, so surface cleaning alone will not reach it. To permanently remove pet urine from carpet, saturate the affected area completely so the product reaches the source, then allow it to air dry. For cat urine odor removal at home, Cat Odor-Off is a veterinary-approved odor eliminator that eliminates cat urine odor instantly and helps prevent cats from returning to the same spot. For commercial carpet cleaners, Odorcide Cat Attack is available in an economical gallon size and is also designed to safely eliminate cat urine odor. For dog urine odor, Kennel Odor Eliminator (K.O.E.) and Dog Odor-Off are both safe, effective, non-enzymatic formulas.
Why does my house smell after I’ve cleaned it?
Recurring odors indicate that the source of the smell was not fully treated. Odor-causing compounds embedded in carpet padding, fabric, or porous materials such as wood and concrete require neutralization, not only surface cleaning. When odors return, it is often because an enzyme-based product was used and covered up the smell temporarily. It is best to use a non-enzyme-based product like Odorcide’s K.O.E. to remove odor at the source.
Why do most products cover smell instead of removing it?
Most products mask odor with fragrance or use enzymes to temporarily relieve it, but do not eliminate it altogether. Odorcide's non-enzymatic formula binds to odor-causing molecules, neutralizing odor at the source and permanently eliminating the unwanted smell.
I’ve tried everything, what can I do to remove a bad smell?
Many of our customers find our Odorcide products after they’ve “tried everything else.” While enzymatic cleaners can be effective under ideal conditions, they often fail in real-life scenarios because they don’t work when deactivated by incorrect pH levels (like using detergents/bleach first), extreme temperatures (too hot or too cold), or non-organic odors. Enzyme-based cleaners have a limited shelf life (typically 1-2 years).
Odorcide’s non-enzymatic odor-elimination formula can be used with other cleaning products; it is effective at any temperature and has an unlimited shelf life. Odorcide has a multitude of non-enzymatic cleaners for your worst smells, including dog odor, cat odor, skunk odor and trash odor.
How do I remove skunk odor from pets, clothing, and surfaces?
Skunk spray contains sulfur-based compounds that bind tightly to surfaces, and washing alone will not remove them. To get rid of skunk smell, Skunk-Off® neutralizes the sulfur compounds at the source and is safe to use on pets, clothing, vehicles, and indoor and outdoor surfaces.
How do I remove the smell of smoke in my home or apartment?
Smoke penetrates walls, fabrics, carpet, and HVAC systems, so all affected surfaces need to be treated. To get rid of the smoke smell for good, Smoke Brake® addresses nicotine and marijuana odors. Pro Renewal® eliminates odor in fire-damaged spaces.
How do I get rid of a musty or mildew smell?
Musty odors come from moisture-related compounds that settle into porous materials. To get rid of a musty or moldy smell, apply Pro Renewal® to neutralize embedded musty or mildew odor in walls, floors, and other surfaces.
Why do clothes and towels still smell after washing?
Standard detergents clean but do not fully neutralize biological odor compounds embedded in fabric. If clothes and towels have lingering odor after washing, run the load again, adding L.O.E.® or Odorcide® Laundry to the wash cycle alongside regular detergent to remove odor from sports equipment, kids, pets, and body odor smells.
What is the best way to eliminate odor in a room?
The best way to eliminate odor in a room is to address the source. The selected product should address the source of the smell to absorb it. Non-enzymatic formulas like those in Odorcide products work best to treat the source of smells. For a quick room refresh, choose Odorcide’s A.O.E. spray for commercial spaces or Loo-Dini around the home.

Pet Professional FAQs
How do I control odor in a busy kennel or grooming facility?
Odor builds from constant use and multiple animals. Treat high-traffic areas frequently and address odor at the source, on surfaces, and in the air. Deep clean frequently and use K.O.E.® for everyday odor management, and A.O.E.® for animals and a quick facility refresh.
What should I use to eliminate animal odor between appointments?
To quickly remove or eliminate odor between appointments in a busy clinical setting, use a fast-acting, pet-safe product such as A.O.E®. It acts instantly to freshen and neutralize odors in examination and waiting rooms with a light, fresh scent. A.O.E. is animal safe and may be sprayed in the air or applied directly to pets with a deodorizing wipe after gland secretions or to remove odor from vomit, urine or feces.
How do I manage odor in outdoor pet areas?
Outdoor odor from feces, urine, or dander absorbs into gravel, turf, soil, and concrete. To manage odor in outdoor pet areas, apply Home & Kennel evenly across the area with a pump sprayer or attached to a garden hose applicator, and allow it to absorb fully.
Professional Cleaning & Jan/San FAQs
How do I eliminate odor in commercial spaces without repeat visits?
Repeat visits happen when odor is not fully eliminated. Treat the full source using a professional-grade, non-enzyme, non-masking product such as Odorcide® Original or Fresh Scent, OdorMed® Concentrate, or K.O.E. Apply sufficient product, and allow proper contact time. These products work by bonding odor-causing chemicals and breaking them down instantly, eliminating the odor at its source with a single application.
Why does odor keep coming back in cleaning jobs?
Odor returns when bacteria have permeated deeper than the surface and were not fully removed. This is common in carpet, padding, and porous materials, where product builds up over time or dirty water is redistributed on floors. Another culprit may be contaminants hidden in carpet padding, grout, or HVAC systems. The source must be fully targeted, saturated, and neutralized.
How do I treat severe or embedded odor?
Severe odor requires full saturation of the affected area. For deep odors, mix Odorcide® Original or Fresh Scent at the recommended ratio, then thoroughly saturate the area and allow it to dry completely. Repeat as necessary until a fresh scent is achieved.
What should I use for smoke or fire-related odor?
For smoke or fire-related odors, Odorcide Smoke Brake® is a highly effective, professional-strength option designed to eliminate odors from carpet, upholstery, walls or vehicles. It uses a formula that bonds with, absorbs, and chemically changes odor molecules on contact. Odorcide Pro Renewal® is another versatile, non-enzymatic solution for treating smoke- or fire-related odors.
For the Home FAQs
How do I get rid of pet smell for good?
Pet odor lingers when it absorbs into surfaces. To permanently eliminate pet odors, use professional-strength non-enzyme products, such as K.O.E.®, as directed: dilute according to label instructions and apply enough product to reach below the surface. Then, allow it to air dry. K.O.E is veterinary-approved and designed for immediate and long-term removal of odor from pet urine, feces and vomit on surfaces like upholstery and hardwood floors when used according to label directions.
Why does my house still smell after cleaning?
The space where you live may not smell fresh after cleaning because odor-causing bacteria are trapped in surfaces where cleaners may not reach. Cleaning removes visible dirt, but odor can remain embedded in carpet, furniture, and fabric. If the source is not treated, the smell will return. Odor must be neutralized, not covered. Use K.O.E.® according to label instructions alongside your household cleaners to eliminate odors at the source and give your living space a fresh, clean scent.
How do I remove odor from carpet, furniture, and air at the same time?
To remove odor from multiple surfaces, including carpet, furniture, and the air, use K.O.E.® by saturating the affected surfaces while using a spray bottle or fogger to treat the air. Dilute according to label instructions, apply the product, and allow it to dry completely.
What should I use for everyday odor in the home?
A.O.E.® is a powerful, non-enzymatic formula designed for everyday use for daily odor control, and may be used on hard or soft surfaces. Spray or wipe as needed and enjoy the light, fresh scent.
Outdoor & Large Area FAQs
How do I get rid of pet or animal odor outside?
To eliminate pet or animal odor outdoors, Odorcide Home & Kennel is designed to eliminate odors on soil, turf, and concrete. Dilute with regular tap water in a pump sprayer or garden hose applicator, apply, and allow it to absorb.
How often should I treat outdoor animal areas?
The frequency of treating outdoor animal areas depends on animal usage and odor level. High-use areas may require regular or preventative treatment. For ongoing, routine maintenance to prevent odor buildup, consider treating high-traffic areas every 30-90 days, depending on severity and odor volume. Odorcide Home & Kennel is designed to eliminate odors on soil, turf, and concrete. Dilute with regular tap water in a pump sprayer or garden hose applicator, apply, and allow it to absorb. Multiple treatments may be necessary for severe or long-standing odor situations.
Can odor be removed from concrete and porous surfaces?
Yes, odor can be removed from concrete and porous surfaces, but the product must be able to permeate the surface. Odorcide works by altering odor molecules upon contact, rather than relying on enzymes, making it effective for long-term, deeply embedded odor issues. Saturate the concrete using Odorcide Home & Kennel, allow it to soak, and ensure it permeates the porous surface, then allow it to dry.
