How to remove old urine stains on carpets and rugs?

Our tips

We recommend a different course of action depending on whether the urine stains are old or new.

Read the general guidelines first and then follow this step by step process for old urine stains:

  1. Use urineFREE Urine Detector to locate stains. 
  2. Saturate all stained areas with urineFREE. Do a colourfast test on a small area.
  3. If the old urine has penetrated the underlay and sub-floor you need to pull back the carpet and treat those areas. If you can’t pull back the carpet then you need to saturate the stain and bleed the urine to the surface and this may take several applications, time and enough product. Note: On the first application the stain may become darker and the odour greater as the urine reaches the surface. This is common. Repeated applications will see the stain become lighter and the odour eliminated.

  4. Allow to air dry. The biological removal of the urine deposits takes place during this time. This may be extended by the application of a non-porous cover such as plastic film for more effective results. Repeat entire process if necessary for particularly stubborn stains. 
  5. When dry, apply a small amount of water to the area and blot it up with a paper towel. It is important to remove the residue as it is sticky.

Why is the stain becoming larger, darker and the odour stronger?

Often stains may become larger, darker and the odour stronger when they rise to the surface – this is common. This is the urine in the sublayers rising to the surface for further treatment and removal. These stains can take two to three treatments with urineFREE and you will see the stains become lighter and smaller upon further treatments until they eventually disappear. The sniff test for urine odour is the best way to double check the urine has gone as even if you can’t see it there may still be urine lingering. This is when you know you have got all the urine. 

Burn marks on carpet

Old urine stains that have not been removed or not removed correctly will have greater exposure to the urine and the acidity of the uric acid crystals. Unfortunately in some carpets & rugs, especially wool blends, the uric acid crystals can cause burn marks that look like a stain but have actually discoloured the carpet/rug.

This is irreversible. urineFREE will remove the urine and in turn the urine smell but it can not remove burn marks. The same applies with urine burn marks on wood floors. However, unlike wood floors where you can sand back and return the wood the its original state, carpets do not have this option. This is why we encourage removing urine as soon as possible for all surfaces and using only a bio-enzymatic product such as urineFREE will remove the urine for good.
