On small fresh spots it seems to work ok but if u discover an old spot that wasn’t treated immediately OR if it is a very large spot, you may want to consider another

On small fresh spots it seems to work ok but if u discover an old spot that wasn’t treated immediately OR if it is a very large spot, you may want to consider another item called “Shop Care: 4X Ultra Synergistic Enzyme Laundry Detergent, 1-gal bottle“ also sold by chewy. It seemed to do a better job with fresh and old/fresh pet messes compared to Natures Miracle.

I bought this to get cat spray out of my clothes. I did a load and they smell si much worse. The product smells a little like cat pee. My clothes are ruined, the smell won't come out. I did not have any clothes in the load roar had a stain so I do not know how it is in stains. I wouldn't buy it for that either. It wreaks.

Good product but the bottle is horrible

I love the Nature's Miracle products and this laundry product came on the recommendation from my daughter after my older dog developed some incontinence problems

I love the Nature's Miracle products and this laundry product came on the recommendation from my daughter after my older dog developed some incontinence problems while she is sleeping. We purchased waterproof blankets we could easily wash and bought the laundry boost to add to it to remove any lingering urine enzymes. The bottle design is absolutely HORRIBLE. You can't shake it as directed because it leaks out around the cap, product goes all over your hands and is wasted. And it doesn't get any better as the volume in the bottle decreases. Happens EVERY time. No way can you hold it upside down to dispense it through the squeeze type bottle because that is even worse. I've resorted to leaving a rag nearby, putting it over the top to shake it and removing the cap to pour it directly into the washing machine. Someone needs to tell them to step up their packaging game or offer it in a gallon size bottle like their other products. Otherwise, it seems to do it's job. No urine odor after the blankets are washed. So, I'm delighted with the product but will be getting a generic bottle to switch it over to in the future to avoid the mess.

I bought this when my cat had a UTI and peed in a basket of towels, and it worked great. It just sat there until I realized it is an enzyme cleaner, and that it can also take the odors out of work out clothes. Left a load of laundry in the washer overnight and now it's a little musty? Add a little splash of this stuff before you rewash it. I thankfully haven't really needed it for my cat since I bought it, but have used it on every other tough odor, and it's great!

Liquid gold!

With two senior cats, an adult dog, and a new puppy in the house, our washer hardly gets a break. This stuff is AMAZING! Seriously - I never let myself run out. Every load of laundry gets some of the Laundry Boost added in and it takes out every stain and odor lingering in there. Keeps clothes, sheets, blankets and towels smelling fresh!

I have tried 6 or 7 other top brand name products to help with my cat peeing and spraying on things in the house and this product actually took care of the smell and any stains left behind, all the other products just covered up the urine smell with their product scent but the urine smell always came back the next day or two.
