Introduction

There are a lot of activities happening around home carpets where everyone tends to gather and have fun. This is the reason why carpets are the subject to heavy soiling. You can have a drink and spill some liquid on the carpet without noticing it. Your pets can urinate the carpet multiple times to mark their territory without your knowledge. Sometimes, the urine also comes from a human.

In this post, we will want to show you how to remove set in urine stains from carpets. Let’s get started!

Dangers of Old Urine Stains on Carpets

The Unpleasant Odor of Ammonia

Old urine stains on carpets can give you a vague smell of ammonia even though the stains have been there for a while. If you do not clean the stains thoroughly, the smell will forever be there. In the case of cat urine, which is considered one of the nastiest smells, the ammonia odor stays strong for a long period of time. This odor is not friendly to your health.

The odor can worsen the health of people suffering from Chronic Obstructive Pulmonary Disease (COPD). COPD is used to describe progressive lung diseases. Its classic symptom is increasing breathlessness. The odor is also harmful to those having asthma – a condition in which the airways of the lungs are always inflamed.

Bacteria and Microorganisms

Whenever a new urine stain is made, bacteria are formed quickly. If you do not clean the stains and eliminate urine odors completely, you allow an ideal thriving environment for harmful bacteria and other microorganisms. These things can attack the immune system of a healthy person over time if the person is exposed to them frequently. They can cause sinusitis – a condition in which the tissue lining the sinuses gets inflamed or swollen. The symptoms include a runny nose and facial pains. Besides sinusitis, healthy individuals can also get watery eyes, airway inflammation, and allergies if exposed to these bacteria.

You can see that for babies whose immune system has not fully developed and the elderly whose immunity has weakened significantly, the bacteria and microorganisms in old urine stains can cause more health damage.

The Formation of Mold

If your carpet has been soiled multiple times and you have not cleaned all the stains thoroughly, there is a high chance that mold is developing under the carpet. Urine of pets or humans can penetrate the carpet and get down to the underneath padding. There are components in urine that create a favorable environment for moisture. And moisture promotes the formation of unpleasant mold if left there for a long time. Mold can definitely cause problems to your respiratory system.

The Costly Replacement of Subfloor

In most households, carpets sit on a padding that is placed directly on the subfloor. Urine can easily find its way through the padding and to the subfloor. Wherever there are old urine stains, the urine has already soaked to the subfloor for a long time. The problem is that the subfloor’s material is wood. With multiple stains, the subfloor wood can become saturated and start to rot eventually. The consequence is you may have to turn your carpet upside down and replace some sections of the subfloor to make sure there is no serious structural damage.

How to Remove Set in Urine Stains from Carpets

Find the Set in Urine Stains

Method 1: Use Ultraviolet Light

This light allows you to see what the naked eye cannot see easily. You can purchase an ultraviolet or fluorescent black light that is small enough to handle. The recommended light bulb is over 12 inches (30 cm). This bulb size lets you scan more area at a time.

Method 2: Use Your Naked Eye in Darkness

This sounds like some sort of supernatural powers, but people actually do it successfully. Just turn off the lights and leave only enough light for you to search on your carpet. Old urine stains should have a greenish or yellow color.

Remember to mark the stain positions as you search. You can do this by keeping a colored tape with you all the time. It is recommended that you use blue tape because it stands out in darkness. When you spot a stain, mark it with a strip of blue tape so that you can come back and clean later.

Remove Set in Urine Stains with Enzyme Cleaners

  • Step 1: Make the stained area wet using cool distilled water. You should pour a little distilled water around the edge of the stain. Move from the edge of the stain to the center.

  • Step 2: Spray your enzyme cleaner directly on the stain. Then, just leave the cleaner to work overnight.

  • Step 3: This is when you assess the situation the next morning. The stain should be gone already. If that’s not the case, apply the enzyme cleaner again. This time, let it sit for the period of time recommended by the manufacturer. Next, use a clean cloth or towel soaked with warm water to scrub the area where you have applied the cleaner. As you scrub, you should see the stain fading gradually.

Note: If you have a wool carpet, choose your enzyme cleaner carefully to make sure it does not have chemicals that destroy wool.

Remove Set in Urine Stains Using Oxidation

  • Step 1: Make the cleaning substance first. Blend ½ teaspoon (or 2.5 grams) of bleach with 1 quart of distilled water.

  • Step 2: Try the solution on a small section of the carpet which is usually hidden and not seen by many people. You do this to ensure that the homemade solution does not ruin your carpet’s color.

  • Step 3: Soak the stained area with the solution. Let it sit more than 10 minutes.

  • Step 4: Use a towel to scrub the area clean and dry. After this step, the stain should fade. If you see results, repeat the whole process several times until everything is gone. Before you pour the solution to the stain again, make sure it is completely dry first.

Note: Do not use this method for wool or silk. Only use for synthetic fibers.

Remove Set in Urine Stains by Vacuuming

For this method, you do not have to worry about the material of your carpet. You also don’t have to create any solution. It’s simple and can be effective.

  • Step 1: Pour cold water on the old stain and use your wet/dry vacuum cleaner to suck the water up immediately. The key here is to suck the water up as quickly as you can. Do it in a matter of seconds. If the stain is really old and hard to remove, use salt water. Do not use soap.

  • Step 2: Repeat the process continuously to maximize the effect. You may have to do several times until the stain is gone.

Note: Not all the vacuum cleaners are designed to deal with carpets effectively, so check this post to know how to choose a carpet cleaning machine for pet urine.
