These stains have to withstand far greater wear and tear than their domestic counterparts, and as a result, are exposed for longer periods of time before they are detected and cleaned. Often they are subjected to a wide variety of different substances, making them very difficult to remove.
Identify the Stain Type First
Many stains can be classified into 3 main categories of protein (food and blood), oil (grease and rubber) and tannin (tea and wine). By first identifying the type of stain it is possible to select the most effective chemical for removal and prevent further damage to the carpet by using the wrong cleaner on the wrong stain.
Pre-Spray and Dwell Time
A professional cleaning solution, which will have a pH level close to that of water, is applied to the stained area and allowed to penetrate the fibre for several minutes. During this time the solution breaks down the soiling and releases it from the fibres. It is then extracted from the carpet using hot water, removing the solution and any remaining soiling from the carpet.
Hot-Water Extraction for Deep or Greasy Marks A useful reference for Commercial Carpet Cleaners Cheltenham is https://intocleaning.co.uk/contract-cleaning-services/commercial-carpet-cleaners/cheltenham/.
For deeply embedded marks or greasy staining, hot-water extraction is the preferred method. This method uses high temperature water, under pressure, which is mixed with a cleaning solution and then extracted from the carpet, taking the soiling with it.
Encapsulation for Surface Soiling
Encapsulation solutions work by releasing a crystallizing polymer which surrounds dirt particles and then hardens around them to form a hard dry residue. This residue is then easily removed with a vacuum. The encapsulation method is particularly effective for removing light soiling from carpets and enables the carpet to be returned to service quickly.
Why DIY Products Often Make Things Worse
Over-the-counter cleaning products for stain removal are often alkaline in nature. They can change the colour of your carpets and leave behind a sticky residue that will attract even more dirt. Professional cleaning products are now formulated with the environment in mind. There is a wealth of guidance on cleaning product ingredients and their environmental impact from WRAP for example. Many commercial customers who search for Commercial Carpet Cleaners Cheltenham are surprised at how one treatment by a professional can remove stains that have been allowed to set for months while the owner or manager has attempted to remove them using DIY methods and cleaning products.
Getting the chemistry right from the start is what separates a stain removed from a stain set.
