The 10 Best Laundry Detergents for Cat Urine

1. Nature’s Miracle Laundry Boost – Best Overall

The best laundry additive for cat urine is Nature’s Miracle Laundry Boost. This isn’t actually a detergent, but it can be used as a pretreatment and an addition to your usual laundry detergent. Nature’s Miracle was made specifically to deal with stains and odors caused by pets, including blood, vomit, and cat urine. It’s phosphate-free but still works to get rid of old stains and odors. It is safe to use in your laundry (although, always read and follow the directions first).

The main disadvantages are that not everyone will find that the urine smell will disappear (at least not right away), and the company recently redesigned the bottle, which seems to be more difficult to use.

2. Lysol Laundry Sanitizer Additive – Best Value

The best laundry booster for the money is Lysol Laundry Sanitizer Additive. This is not a cat urine laundry detergent, but it is designed to be added to the laundry with your regular detergent or can be used on its own to remove stains and odors (and bacteria). This product is used by commercial laundry services to remove tough stains and odors. It can kill 99.9% of all kinds of bacteria, including pathogenic and odor-causing bacteria. It doesn’t contain bleach or phosphates and can work on cat urine.

On the downside, while it doesn’t affect everyone, some people seem to come down with some form of rash or hives when coming into contact with fabric that has been washed with this product. You might want to avoid this product if you have sensitive skin.

3. Skout’s Honor: Professional Strength Laundry Booster – Premium Choice

Our pick for premium choice for the best cat urine remover is Skout’s Honor Professional Strength Laundry Booster. This is an additive rather than actual laundry detergent, but when used with your detergent, it will remove cat urine stains and odors. It is biodegradable and environmentally friendly because it doesn’t contain any harsh chemicals. Skout’s Honor is designed to remove tough odors and stains such as vomit and blood (in addition to the urine), and it offers a 100% satisfaction guarantee for a full refund. In addition to all this, it also provides a day’s worth of food for a needy animal for every bottle sold.

However, it is expensive, and it might not necessarily work on all odors. You should do a small spot-check before use, as discoloration might occur.

4. Febreze Laundry Pet Odor Eliminator

Febreze’s Laundry Pet Odor Eliminator is an additive that you use along with your laundry detergent. It is designed to eliminate odors instead of just covering them and is specifically meant for pet odors. It can be used to pretreat before washing and is safe to use with all detergents, fabric softeners, and bleaches. It can also be used in HE washing machines.

Unfortunately, it is a little expensive, and it might not be as effective on older stains that have had time to set in.

5. LaundraPet Premium Laundry Detergent

LaundraPet Premium Laundry Detergent is suitable for pet stains and odors and can clean up to 96 loads of laundry. It is made with non-soap ingredients that provide three times the cleaning power of other detergents and is also low suds and non-toxic.

The disadvantages are that it is on the pricey side, and it won’t always be able to remove the cat urine odor.

6. Persil ProClean Power-Liquid Laundry Detergent

Persil’s ProClean Power-Liquid Laundry Detergent is great for people with sensitive skin and does not contain any perfumes or dyes. It can wash up to 64 loads and is designed to be gentle on skin and fabric but provides strong cleaning power. It is phosphate-free and hypoallergenic.

The biggest problem with this detergent is the packaging. Many containers arrive leaking, so you might want to consider buying this one in a store rather than through delivery.

7. Zero Odor Laundry Odor Eliminator

Zero Odor Laundry Odor Eliminator works as an additive to your cat urine laundry detergent or regular detergent to eliminate smelly odors from sweat, smoke, and pets. It is also designed to clean your washing machine at the same time. It is biodegradable and non-toxic and doesn’t cover up odors with perfume.

On the downside, while the label states that it doesn’t use perfumes to mask odors, this product has an unmistakable scent, so it’s not hypoallergenic. It is also somewhat expensive.

8. All Liquid Laundry Detergent

All’s Liquid Laundry Detergent is a great laundry detergent if you have sensitive skin. It contains no dyes or perfumes, and it has enough for about 49 loads. This detergent is advertised as the number-one brand recommended by dermatologists, pediatricians, and allergists, and it is effective against cat urine.

The issues with this detergent are that it isn’t always effective against odors, and it tends to arrive leaking during delivery.

9. Dead Down Wind Laundry Detergent

Dead Down Wind Laundry Detergent is made for hunters as a way to keep odors down so they can’t be scented while outdoors. It can work just as well for cat owners looking to eliminate that urine smell. It works for sensitive skin, is unscented, and contains enzymes to help break down stains and odors. This cat urine laundry detergent cleans clothes, removes odors, and protects your fabrics, which enables them to last longer.

The primary disadvantage is that during delivery, some of the bottles are prone to leaking.

10. Biz Laundry Detergent Powder Booster

Biz Laundry Detergent Powder Booster is an additive for your laundry detergent, and it contains enzymes that are effective against cat urine. It also includes whitening and peroxide agents to help whiten your wash and add extra power against stubborn stains and odors. You can pre-treat or pre-soak the fabrics before washing and add it to the washing machine for additional effectiveness.

However, you might find it to be a little on the expensive side (at least compared to some others), and some users might not find it effective enough against odors.

Buyer's Guide: Selecting the Best Laundry Detergents for Cat Urine

Before you decide on a new detergent or additive, you might want to check out our buyer’s guide. We go over a few things that you'll want to think about before paying for a product.

Scented or Unscented

Most additives and detergents will be scented. If you don’t mind a strong, perfumey scent, this is nothing to worry about. But if you have allergies or sensitive skin, you’ll want to check the ingredients before purchasing. It’s important to note that a strong fragrance won’t remove the scent of cat urine from your clothing. You want to aim for something that eliminates the odor and not just covers it up.

Enzymes

The use of enzymes is the most effective way to remove cat urine odors from anything. They work to break down the urine’s pH to remove odors and stains. This will also help prevent your cat from urinating in the same spot repeatedly because that scent will disappear and won’t keep drawing your cat.

Testing

When you are trying to eliminate tough scents and stains, the additive and detergent tend to be stronger. You must test a spot (particularly on a more delicate fabric) in a more hidden area before throwing it into the wash entirely. This way, you won’t accidentally ruin your favorite shirt or blanket.

If your cat experiences frequent pee accidents,you should have your vet assess them for underlying health issues.

Delivery

Many negatives of these products tend to be about leaking during delivery. This isn’t a common occurrence but it’s always a possibility. We don’t know for certain if it is due to the design of the containers or the delivery service itself, but it’s good to be aware that this could happen, and you might want to consider shopping for the product in person.

Time

The older the stain, the longer you will want to pre-soak it before actually washing it. Double-check the product before purchasing and read the instructions carefully. Not every detergent or additive will work on old stains.
