How To Remove old Dog urine stains from wool carpet And Area Rugs?
Method 1: Remove old dog urine from Area rugs and carpet With cleaning products (Without Vinegar)
>>> Tools and cleaners you’ll need to get started: <<<
1. Either a carpet cleaner machine or a small shampoo machine:
- A rental rug cleaner: Be sure it does not use steam or a beater as these will damage a wool rug. The Rug Doctor is the best I have found. But they are big and expensive. You can rent or buy one.
- A small rug shampoo machine: I bought a Little Green Machine, which is very small and useful for many other jobs. It does a good job.
- A Wet Vac Machine: You can also use a wet vac for removing pet stains from your wool carpet. It deep cleans your carpet by flushing cleaning solution into the carpet and vacuum out the dirty water.
2. Commercial or homemade cleaner
- Commercial cleaner: Check that the ingredients will not shrink or otherwise harm wool. See my recommended cleaner here that I know and trust.
- Homemade cleaner: Find the Homemade cleaner recipes here.
Steps to follow: ( Using a machine and commercial carpet stain remover )
Step 1: Put a pad or old sheets or some other absorbent padding under your rug to absorb the moisture and the stains. Your actions will push the stains into the pad shielding your floor.
Step 2: Test whatever cleaning solution you have selected on a small portion of the carpet that will not be visible. Perhaps a corner that will be under furniture or against the wall. Use the solution as directed on the packages and watch carefully.
How to Do The Test:
Commercial rug cleaner machine have separate tank for cleaning solution and dirt water (for used solution).
If you see bright colors in the used water tank, stop and rinse the spot, as that is your carpet dyes. Then spray with white vinegar to stop the chemical action.
Vinegar is both chemically active and also a neutralizer, similar to the old stop wash that came with permanent wave lotion.
If all the cleaners you try strip the color, then you need to hire a professional company. Try contacting the company that made your machine for their recommendations for professional cleaning.
However, if the color looks like the rest of the rug, you can use the cleaner you tested. Follow step 3.
Step 3: Apply your cleaners as directed using the machine you selected. You can also use your own homemade cleaners in these machines.
Step 4: After a few minutes of cleaning the affected area, stop and blot it dry. You can blow dry the spot using a blow dryer on low with no heat or an electric fan. Never dry your rug in sunlight. Just use fans blowing across it to dry it.
Step 5: Check the underside to see if it is dry after 1-8 hours. If you got your rug wetter than that you got it too wet.
Some people suggest you use newspaper to blot the liquid. Do not do this unless you have blank newsprint such as is used with moving and packing companies. The ink in newspaper smears and add different chemicals to your carpet as you blot.

Steps to follow:
Step 1: Vacuum the wool carpet first to prevent making mud with the dirt in the carpet. If there is lots of dust in the carpet sprinkle with corn starch on the dry carpet and gently beat it in. Leave for an hour and vacuum.
Step 2: Put the place mat under the rug where you need to clean to help it not get too wet. If the rug gets very wet you will have to blot it as dry as possible.
Step 3: Line up your chosen hand tools you need from the list.
Step 4: Examine the urine stain. How dark is it” How old is it. If it is very dark or very old, start using a dry shampoo( corn starch). Dust the carpet stain thoroughly with corn starch. Use a soft brush, wooden spoon or rubber mallet to lightly rub it into the fibers. Leave for 1/2 hour and then vacuum the spot. Inspect to see if the spot is lighter.
Step 5: If the spot is small try one tablespoon of medical strength hydrogen peroxide with one cup lukewarm water. Brush on the spot well with a soft brush.

When the carpet begins to get damp blot dry with a rag or towel.
