How do you remove cat urine from concrete?

Question

Bought an old house and the basement is nothing more than a full basement with poured foundation, but it's home to 3 - 5 cats and reeks of cat urine.

Answer 1

am not sure a small nuke maybe...cat urine is powerful stuff

ps i did some looking around and found this
Forewarned is forearmed, what you need in your arsenal are the following items:

A black light - A black light with a fluorescent tube, not an incandescent tube is what you need. The black light will (when turned on in complete darkness) make cat pee glow bright yellow for new stains, and light yellow or even green for old stains.

Rubber gloves - Cat urine is caustic. You want to be wearing rubber gloves anytime you are removing cat urine.

Sponges - if you have cat pee on your floor or carpet, you have a cat that is either ill and can’t help herself from peeing wherever she may be, or she is stressed about something going on.

If you see your cat peeing on your rug or carpet, don’t shout at her and rush over to move to the litter pan. Simply grab an absorbent sponge and slide it under her, so most of the cat pee catches in the sponge.

Cat pee is very caustic and it travels quickly. If you can catch it before that happens, you are ahead of the game. That is why sponges come in handy in the battle of the cat pee.

Cloth diapers - these are the best as far as absorbent cloths go. Have a stack in your Combat Cat Pee Box.

Neutralizers - You need one of the following neutralizers: Anti-Icky Poo, Nature’s Miracle, Zero-Odor, or Urine-Off! These are all molecular-based neutralizers that break-down the enzymes in the urine, dissolving them completely and eradicating the smell. These are all products that I have used, and I know from experience that they work.

Feliway Spray - this is the finisher for cat urine odor. After the neutralizer has had a chance to work, Feliway Spray is applied to the area.

When it comes to tile floors, getting rid of cat urine is simple. Soak up the urine with an absorbent diaper, and then rinse with hot water and household cleaner. After that has dried, apply a neutralizer to the area to remove any lingering odor.

For carpets, cat urine is much more difficult to remove. Not only do you have to worry about the carpet fiber, but also the carpet backing and the padding which can quickly become saturated with cat pee resulting in bacteria, corrosion and mold.

First, blot up as much of the cat urine as you possibly can with the cloth diapers.

Next, apply the neutralizer. Make sure that you allow the solution to soak through. Give it about 5 minutes to sit on the stain, and then taking another cloth diaper blot the area gently. Continue blotting (not rubbing) the area until it is completely dry. You may have to repeat this process more than once.

Finally, spray the area with Feliway Spray and then cover the area with a thin sheet or blanket, weighted down for at least six hours.

Answer 2

I had a similar problem. I poured white vinegar on the floor and left all the windows open for a week until the vinegar evaporated.. Then I used a product called "Kilz" which is in the paint section of most home improvement stores. I painted the floor with Kilz and the smell was gone.

Answer 3

I had the same problem when I bought my house (three dogs lived in the basement, most of the time). Buy some concrete paint, and a roller, and paint the basement.

Answer 4

When I sold my house I had to have the carpet replaced in one room because of my cat. The carpet installer had some kind of product he used to basically bleach the concrete, but it wasn't regular bleach.

Answer 5

I would try cat blood. Sure, it may or may not clean up the urine, but they would learn their lesson.

Ok, I'm not serious about this, I would not hurt a cat. I just have a dog who has ruined my carpet with pee and it really makes me mad.

Answer 6

try using the scented cat litter, that will dry it all up. seriously. have you ever gone to a gas station and seen cat litter all over the ground. try saw dust too

Answer 7

trying mopping several times with plain white vinegar. worked for me!

Answer 8

start scrubbing b/c the longer you wait the longer the smell stays.

Answer 9

Answer 10

1 gallon of semen
