HOW TO GET RID OF CAT URINE SMELL OUTSIDE

Whether you have an outdoor cat or your yard is a stray sanctuary, you've likely got cat pee odors that have built up over time. This stench can linger long after it's been absorbed unless you treat it appropriately. To truly get rid of the smell, you need to remove the odor at its source, not just cover it up. For this reason, we recommend using a bio-enzymatic outdoor odor elimination product.

Directions for Getting Rid of Cat Urine Smell Outside:

For best results, use the product during cooler times of the day, such as dawn or dusk, when it can stay damp longer.

1. Shake well. Shake the Simple Green Outdoor Odor Eliminator hose-end sprayer thoroughly, and keep pets out of the area during application.
2. Connect your hose. Attach a garden hose to the back of the sprayer, pointing the nozzle away from your face.
3. Apply the cleaner. Turn on the water slowly, using low to moderate pressure. Push the safety tab forward toward the hose and turn the nozzle counterclockwise to the "On" position, then spray down the area.
4. Let it soak in. Let the deodorizer sit for 10 minutes to penetrate the area. Avoid letting it dry during this time, as the longer it stays damp, the longer bacteria have to digest the organic soils. In windy or warm conditions, lightly mist the area with more product to prevent quick evaporation.
5. Allow the area time to dry. Let the affected area air dry and repeat the process if needed.

TIP: Applying this product at dusk gives it more time to stay damp and active. You can also lightly mist the treated area with water afterward to reactivate the formula for additional deodorizing action.

Why Home Remedies Don't Work

Urine is about 95% water, with the remaining 5% made up of proteins, uric acid, salts, minerals, ammonia, and other compounds. As cat urine dries, bacteria break down the urea it contains, producing that sharp ammonia smell. As it continues to decompose, it releases thiols — sulfur-based compounds that make the odor even stronger. Uric acid, in particular, isn't water-soluble and bonds tightly to whatever surface it touches, which is why it's so hard to eliminate.

Baking soda, white vinegar, soap, and hydrogen peroxide may neutralize odors temporarily, but on a humid day, uric acid crystals can reabsorb moisture and release foul odor all over again. Other home remedies, like lime, can actually be dangerous to your family and your cat's health.

Orange peels and cayenne pepper are commonly used to deter cats from entering yards, but they do nothing to eliminate existing odors. Cayenne pepper can also be harmful and irritating to cats.

Why Enzyme Cleaners Work Better

To truly remove cat urine smell outside, choose an enzyme-based cleaner with live bacteria that break down and eliminate the source of the odor, rather than just covering it up. Enzymes break uric acid down into gases, which evaporate naturally as the area dries.

Simple Green Outdoor Odor Eliminator uses naturally occurring bacterial microbes that break down uric acid crystals and other organics to neutralize bad smells.
