Tip #1: If you can catch it while it is still wet this will work wonders. Salt. Plain old table salt. Cover the area of the carpet GENEROUSLY with salt and leave it alone for at least 2 hours. The salt will "draw" the moisture out of the carpet. Then you can just sweep/vacuum it up later. This works great on any kind of carpet stain.
Tip #2: Try vinegar. I use this all the time. Pour the vinegar directly on the urine stain - I would use 1/2 cup if this really is a small stain. Then put a towel over the spot and step on it to remove the liquid. The vinegar will remove the urine smell and the vinegar smell will disappear soon. If a stain remains, rub the area with a baby wipe.
Tip #3: Get as much of the stain up with blotting as possible, spray Shout onto the carpet, and gently scrub with a damp cleaning rag or two, depending on how large the area is. Occasionally it takes two times, but usually works in one.
Tip #4: I have two older cats that occasionally pee on the dining room floor. I tried everything to get the stains up, and eventually the only thing that really worked was Oxy Clean.
I buy a bucket of it at my grocery store, and in a separate container create a watery paste with it. Then apply it on the entire area and work it in with a brush. Then I rinse it with water and vacuum it up with our wet vac. I was shocked at how well it worked. There was no yellowing left at all.
Tip #5: There are two things you could try. One being a mix of
hydrogen peroxide and about half the same amount of ammonia. Spray this and
let it sit for about 30 seconds and blot with a dry towel. Another
thing is the pet odor sprays, bb&bd has a good cheap one that works
wonders and does not stain dark carpets. Good Luck!...Annie
Tip #6: If it's on the carpet try using a product with enzyme in it.
Dollar tree sells that stuff in the pet section. It's called Dog's best
friend or something like that. It is a urine remover. It really works.
My male cat likes to pee in my son's room and I have tried everything to
get the smell out nothing worked until I tried this.
It takes the smell and the stain out. And for $1 you can't go wrong...Angela
