Pet urine such as from Dogs and Cats can cause serious odour problems in carpets both with synthetic carpets such as Nylons, Triexta and woollen carpets in Auckland.
Urine is a complex substance which goes through various changes after being deposited in the carpet. These changes which occur are responsible for the offensive odour which can fill the airspace of the home.
Urine begins as an acid substance which when exposed to the carpets can damage the fibres and discolour the dyes particularly Woollen carpets, Cotton floor coverings, Wool rugs, and Goat hair oriental rugs can be harmed by the strong acids.
The persistent and foul odour is caused later when the urine in the presence of bacteria begins to metabolise and breakdown. Strong and volatile ammonia is off gassed into the airspace and can fill the rooms of the house.
The urine eventually metabolises from an acid into an alkaline. This process will further depreciate the dyes in natural fibres. As the urine changes, the acids become solids morphing from a liquid and forming sharp crystals of Uric Acid.
Gravity tends to take the urine as a liquid form down deep into the carpets pile, often DIY cleaning to mop up the urine or treat it with a chemical often an antibacterial to control the eventual odour issue inadvertently assists the urine to reach deeper into the pile and into the carpet construction and backing material. It is not unusual to find urine has passed through the carpet and into the underlay/cushion under the carpets.
When Uric Acid Crystals form deep in the pile, the carpets backing or the underlay, their microscopic sharp shards of crystal are very difficult or impossible to remove. In these cases, replacing the underlay may be required, the floor may need sealing and the carpets backing may need treatment.
Steam Cleaning for Urine in Carpets
Hot water or Steam extraction method is the best way to remove urine contamination from the [Nap] visible carpet fibres. The Steam extraction Method for cleaning carpets will flush out contaminants such as urine and leave the nap free of foreign substance. However when urine has made its way deeper in the pile into the carpets backing material or the underlay, further treatment may be required.
Chemical Neutralisers for Urine Contamination in Carpets
Chemical neutralisers may be required to control residual urine and its odour causing characteristics. Specialised chemistry using antimicrobial agents to control the bacteria associated with the odour, Oxidising agents may be utilised to kill bacteria and destroy Uric Acid Crystals [Salts], odour absorbing chemistry and Ionic charged chemistry to reduce to bind Uric Crystals use to fix to the carpets fibres and construction making them easier to extract.
