Can you use it on leather?

Answer by ChewySep 26, 2023
The manufacturer does not suggest using this product on leather items.

can this be used in carpet cleaning machines for pets?

Answer by ChewyApr 29, 2025
It is recommended to saturate the affected area, let sit for 5 minutes or more, and blog with a rag. It is not intended to be used in a carpet cleaning machine.

Miracle workers.

Takes all the urine odor out! Was washing so many wee-wee pads due to cat incontinence & this took out all that dusky urine smell that other cleaners left behind

Takes all the urine odor out! Was washing so many wee-wee pads due to cat incontinence & this took out all that dusky urine smell that other cleaners left behind. LOVE that is enzyme based & not chemical based because I didn’t want the added chemical smell in my cat’s environment.

Absolutely useless

Didn't do anything to get rid of (or even mask) odors when cleaning litterboxes or the one spot on our catio where our big guy sprays.

FINALLY!!!!

So my male cat went in my sunroom(early February) and although I caught it as soon as it happened and doused vinegar, baking soda, multiple different enzyme cleaners

So my male cat went in my sunroom(early February) and although I caught it as soon as it happened and doused vinegar, baking soda, multiple different enzyme cleaners and nothing helped but those that did were 100% temporary! I would leave it to do its magic and come back hours or so later and I’d still smell that strong disgusting pee smell! YUCK! After searching for months what I could do before extreme measures I finally ordered this based off reviews and it came in the mail yesterday (5/21) and I did not hesitate to mop my entire sun room. I was so scared I may smell it the closer I approached the sunroom the next morning. 10/10 no smell no nothing!!! Also my wood is veryy old and holds on to smells much worse than I guess newer wood floors? Either way this gotten odors out that were in there from YEARS ago! This stuff is the truth!

The BEST pet odor stain remover!

I wish they sold this in stores everywhere. The bio enzymes in this really work and the smell is natural and pleasant, not chemical and gross like most pet sprays

I've been using the Biokleen Bac-Out cleaner for 7-8 years now. I usually just get the lime-ish smelling one, but this lavender one seriously smells amazing. This is the only cleaner that works for me in getting the vomit stains out of the carpet. In the past, I used to waste a lot of product by spraying and scrubbing vigorously until the stain is gone. Nowadays, I usually saturate the area and then put a thick layer of paper towels over it with a heavy object on top to soak up the liquid. Usually, doing this 1-3 times will remove all the stains. Totally worth every penny, IMO. Thanks to Chewy, I was able to get an awesome deal by buying 4 gallons and stocking up.

Pleasant to use & effective.

Works well. Scent (We tried both Lime and Lavender/Lime) is mild and pleasant: pleasant to my human nose, mild enough to not bother the cats.
