Yes, this is a horror story, stop here if you have a weak stomach. My
sister-in-law lived in a house for eight years with approximately 40
cats and she was a smoker. The house was the cats' liter box. I
have thrown away everything, all furiture, appliances, kitchen
cabinets, and removed the vinyl flooring with a shovel. The house is
empty. The house has been powerwashed with just water (starting with
the ceiling and working down to the floor). The power washing helped
alot but the smell of cat urine is still present. The house was built
on an 18 inch thick concrete slab (unsealed) The house is
approximately 1,100 square feet in size. The walls are covered with
painted drywall with the main room walls covered with wood paneling.
Prior to the powerwashing a blacklight inspection revealed urine on
the lower 2-4 feet of the walls. I am looking for an answer to remove
the cat urine smell from the concrete floors and walls. Is there a
brave chemist or equally brave professional out there with a serious
answer? Is replacing the bottom 2-4 feet of the walls and associated
insulation part of the answer? (Gasoline and a match is not a
solution, my father-in-law built this house and it holds great
sentimental value to my husband and mother-in-law.) |

Hello Monsterthecat,
If removing the source of the urine smell is difficuult, have you
instead considered trying products that can mask the smell? For
example, an ozone generator?

Thank you for your request for clarification. By "mask the smell",
did you mean that you have a no-fail sealing method for the concrete
floor? Otherwise, I am not looking for a deodorant or perfume unless
there is sound scientific evidence that this method is a
professionally accepted standard and that it works. A final solution
resulting in a 'cat urine plus whatever odor' is not acceptable.
Isn't there a nice chemist or chemical engineer out there who can help
with this "let's examine this problem at a molecular level and break
the molecular bonds of the odor producing volatile organic compounds,
proteins, etc., " solution?

PS: The difficulty factor is not an issue. We already dug a treach
with a bulldozer just to bury the cat urine saturated furiture,
flooring, appliances, etc., in 100 degree weather. Anything less than
that wouldn't be too bad.

Hello Monsterthe cat,
Mark, an IICRC Certified Master Cleaning Technician and IICRC
Certified Master Restoration Technician posted some useful
information and advice regarding the removal of strong cat urine
smells.
Read about it here:

Does this help?
Thanks,

Yes, this way helpful. Is the final portion of the solution, i.e.,
sealing the concrete, an absolute requirement? Can't all the urine
be neutralized chemically Thank you.

absolute requirement?
Yes, I believe that sealing would be the only solution.
According to Mark, the IICRC specialist that I cited previously, a
cat urinating just 6 ounces per day is 17 gallons of urine per year.
Your sister-in-law lived with 40 cats for eight years. That would be
over 5000 gallons of urine.
He says that ?Enzymes can work, but in situations of strong odor, they
*never* will.?
He goes on to say: ?you cannot remove dried urine from *porous*
surfaces like wood and cement. You must *seal* the unremovable urine
in thecontaminated surfaces. It must be sealed from *exposure* to heat
andmoisture. If warm, moist air does not contact the dried urine
crystals, youwill NOT smell the urine.?
I see no other solution to this problem.
Would you need additional information?
Thanks,
Bobbie7

Hi,
Perhaps the simple chemical solution you're loking for is pure,
undiluted bleach such as Chlorox. I've effectively used bleach for
just about every source of foul odor in our house -- from left behind
food odors and animal odors which includes dead rat odor. Try it if
possible and see if it works. Please let us know the result.
