Some of this color change can be attributed to the strong ammonia that forms as the urine passes through bacterial and chemical change. If left for days or weeks, depending on the fabric or floor type, it will change the dye structure, therefore causing permanent staining.
Fill the spray bottle most of the way with water. Add hydrogen peroxide at a ratio of 1:4 (1 part hydrogen peroxide for every 4 parts water). Spritz the old urine stain liberally and leave it to work for 10 minutes. Then using the cloth, blot it up.
Getting urine stains and smell out of fabrics can be hard, but when left to dry, they can become permanent, smelly nuisances that ruin mattresses, clothes, and even carpets.
Laundry Detergent and Vinegar
Another method to remove pet urine from soiled laundry is to begin with a cold-water rinse under a faucet, aiming the water directly at the stain. Then wash the item on the hottest recommended washing machine setting, using detergent along with one cup of white distilled vinegar.
Old or dried urine stains can be difficult to remove, often leaving carpet fibers permanently discolored or with an unpleasant lingering odor.
The bacteria that grow in pet urine stains are not particularly dangerous to regular, healthy people. However, getting rid of these stains can be quite bothersome. For people with healthy immune systems, these bacteria can cause problems like sinusitis, allergies, and airway inflammation.
Reason # 1: Wicking.
Many times, the spot that is being removed has seeped into the backing of the carpet. This is common with pet urine, beverages, and anything that is spilled in “volume”. The material dries in the backing and the cushion (pad) of the carpet.
Mucous membranes may also take on a yellow tinge. If you see this color in your dog's urine, there is a possibility that he has liver disease and should be seen by your vet immediately. Orange and brown urine can occur when muscles release a mixture of oxygen and myoglobin in times of stress.
If the urine stain is dried or old, soak the fabric in a solution of cool water and oxygen-based bleach, such as OxiClean, Clorox 2 for Colors, or OXO Brite. Follow the directions on the package on how to mix the solution.
That unpleasant stench lingers long after the liquid has been absorbed, and can last months unless treated properly. To effectively remove these offending odors, you'll want to make sure you're eliminating them, not just covering up the smell (as many products do).
If you leave urine untreated, you may wind up with a difficult to remove yellow stain, or worse, loss of color pigment in carpet. Over time, urine salts become highly alkaline, and can bleach out your primary carpet dyes, starting with the weaker red and blue.
Certain types of fibers, such as wool, cotton, silk, and some nylons are particularly susceptible to permanent staining from coffee, tea, wine, etc. Be aware of hot liquids, especially. Of course, bleach and household chemicals (see below) can cause permanent staining as well.
First, try using a damp cloth to blot the stain. Then, make a solution of one part white vinegar and two parts water. Apply this solution to the stained area with a cloth or brush and let it sit for a few minutes. Finally, rinse the area with clean water and blot dry.
Vinegar is an effective cleaner to use in removing pet stains and urine odors from mattresses, couches, and other materials, but it is still important to treat the stain as soon as possible. The longer you let it sit, the more likely it is to set.
Clean the Mark
If you don't remove the trace odors of the marking, your dog will likely re-mark the same area. Be sure to avoid harsh chemicals or fragrant cleaners; dogs interpret these odors as “challenger” scents. Instead, use an enzyme-based cleaner that neutralizes the odor to remove all traces of it.
Brown spots: If dog pee causes too much nitrogen in your soil, patches of grass will fade to yellow and eventually brown as they die. You'll see a ring of dark green grass around the brown, where more diluted urine fertilized the grass instead of killing it.
Your dog may also have orange urine if their urinary tract is infected by bacteria (UTIs). UTI pee is often cloudy or pinkish but can sometimes appear as dark yellow or orange. Additionally, bladder stones, such as those composed of calcium or urate crystals, can cause orange or rust-colored urine.
Mix one-half cup of three percent hydrogen peroxide with a teaspoon of dishwashing detergent and apply to the stain. You can use the scrubbing brush again to thoroughly clean the carpet. Once dry, vacuum the area.
Thus, it's a good idea to shampoo your carpet once or twice a year, especially if you have pets in the home. Carpet shampooing can be accomplished by hand or steam cleaning using heat, water, and detergent to loosen and remove tough stains, spills, and odors.
you're training your pet or your toddler, seeing a piece of clothing ruined by urine stains can be frustrating. Fresh urine stains can usually be removed with normal laundering. If the stain has dried, it will take a bit more effort. Fortunately, there are some easy fixes that will remove that spot for good.
However, aside from dog urine stains being unsightly and smelling bad, they can also be quite hazardous to humans. One of the dangers of dog urine is the presence of ammonia. Ammonia is a substance that can easily cause respiratory problems, even if inhaled in smaller quantities.
When urine has dried, it often leaves a yellow hue. On white carpet, the urine can look almost neon, and on darker carpets may manifest as discoloration or spots with an odd glow.
