Urine removal techniques for carpets and rugs

It can cause stress and upset. And we love our canine dudes.

To start with what is Urine?
This is the body’s way of flushing out its liquid waste.
The waste is mostly water around 95%, with rest being made of chloride, urea, ammonia, proteins and salts.

So why does wee smell?
Now, this information is mostly for animal accidents, the same principle does apply to human incidents also.
Urine can be smelly, have different colours, more so if medicines are being taken as this also passes through the kidneys.
So we will talk about how to remove the urine, and removing the odour from your carpet or rugs.

You may have researched via the web on how to eliminate this smell. It may tell you to use baking soda and leave for a few minutes. This will not work. In fact this will probably make things worse. Other ingredients will neutralise.
You don’t want to neutralise to want to eliminate the problem returning.

We place urine removal into three categories. Light, medium, and contaminated.
So a light urine removal can either be undertaken by the homeowner or a professional carpet cleaner.

The process is for the homeowner to remove as much moisture as possible. You can do this by placing a dry towel over the area concerned. And stand on the towel for about thirty seconds.
We advise against using the shop products. The reason for this is that they contain bleaches and can damage the fibres when applied. A better approach would combine water at 75% and white wine vinegar at 25% in a spray bottle. Use this to help remove any surface incident.

The most obvious issue with urine is the smell.
The smell will either be the ammonia or bacteria that has leaked into the backing.
Either way, you will want this odour to be removed.
Another issue is that some fibres react with this liquid excretion.
Depending on what is excreted, and the fibre which is receiving the contamination, these will have different effects on the fibres.
As a rule of thumb, there are three colours which will determine if damage has been done.
If the fibre turns to a darker colour, i.e. black, in our experience this can be removed and the original colour revived.
If the fibre has turned yellow or orange this means that bleaching has occurred. This can be fixed however this is all dependent upon the fibres itself being recoloured. Not all fibres can have this corrective process applied.

Light Removal

If you have caught the incident quickly this is what we would advise the homeowner to do.
1/ Absorb as much moisture as possible. Place a towel over the area and press down. Do not rub. Repeat the process until you think no more moisture can be removed. Hopefully, that will resolve the issue for you.
When we remove spot areas this is what we do.
Using our carpet cleaning machine we will flush the area using just cold water. We ill then take a ph reading using litmus paper. If we are happy with the reading will proceed.
Next, we will apply a dedicated chemical. We leave this to dwell for a few minutes and again re flush the area.
Finally, an enzyme chemical is applied and we leave this to dry naturally.
Some customers want this service for peace of mind.

The next level is medium contamination
This cannot be undertaken by an amateur.
In this process, we need to identify all the areas of concern.
We do this by using a Uv torch. The UV torch will change the colour of the carpet indicating where the urine is. We will also use a moisture metre to determine if the liquid has penetrated the backing and leaked into the underlay.
Once each area is identified we will leave a marker, be it a circle of chalk or a piece of paper.
As in the light removal process, each area is flushed by using cold water. The tool we use for this is a square metal head of around 6 inches square.

Using our body weight we place the tool on the area to be cleaned and stand on it. This allows for as much contamination and moisture to be removed. Once all areas have been addressed, the whole carpet is then steam cleaned. Once the clean is completed an enzyme odour chemical is applied and brushed into the carpets. We leave this to dry naturally which takes around 3 hours.

Contaminated urine cleaning.

This is extreme and it all goes down to your budget.
If the survey suggests that underlay is wet, and the physical investigation agrees with this, then the only course of action is to dispose of the underlay.
The underlay acts like a sponge. We can clean the carpets but not the underlay.
So the room needs to be emptied.
Next, we need to uplift the carpet and remove and dispose of the underlay.
The subfloor will need to be treated. We will sometimes put the carpet back in place and clean it thoroughly.
Uplift it again. Fit the new underlay and carpet.
This time the carpet will be cleaned with the help of enzymes and deodorisers.

So as an example for cost to replace the underlay £100 on a typical living room.
To uplift underlay, refit new, refit carpet, and then clean the carpet would be about £140.00

Or you may want to renew the whole room in question.
And that could cost you in excess of £1000, if not more.

If you do have a puppy it may be prudent after having your carpet, rug, or sofa cleaned, to have it protected with a stain protector.
This will provide you with those extra minutes to remove the accident quickly, and not allowing any liquid to seep into the backing of your fibres.
