Carpet cleaning is what’s needed if you have a bad stain, before trying to remove the stain with a cleaning agent, a professional carpet cleaner would firstly try with just steam, if this doesn’t work then a low pH product is tested to see if the stain can be lifted.
Using a low pH cleaning solution to start with will limit the risk of damaging the fibres, and even the risk of locking the stain in and it becoming permanent.
Carpet cleaning requires a good well trained technician and well maintained equipment, even with the best steam cleaning machine will alone give the desired results, the technician has to able to identify and understand the carpet fibre in which they are cleaning.
Many carpets over the years have been ruined due to lack of experience when engaging a non-trained carpet cleaner.
When having a carpet clean done there are some simple steps to follow to ensure you are hiring the correct cleaning company.
Firstly a good technician would do a thorough inspection of the areas to be cleaned, and then explain to the customer what is to be expected of the clean at the end result.
Once the customer is happy with the technician then a thorough pre vacuum of the carpeted area is to be carried out using a power headed vacuum cleaner and paying attention to the edges of the carpet, where they meet the shirting boards. Vacuuming will remove 60-70% of dust particulates. This is one area so many untrained cleaners make mistakes in; the edges are what will make the carpet look good or bad at the end of the job, so a thorough pre vacuum of the edges is so important to obtain a great result. The main reason for this is the edges always have lots of dust build up, where day to day vacuuming has been missed, when the pre stain detergent is applied to the carpet, the dust then turns into a liquid and can easily stain the edges of the carpet.
After the vacuum then the pre spray solution is applied, this is done with an inline sprayer with hot water to give the best chance of removing the dirt and stains from the carpet. An even spray will give the best results and attention to more server marks.
After the pre spray, to gain the best possible results it’s best to agitate the carpet with a rotary scrubber; this will work the pre spray detergent into the carpet fibres and loosen the remaining dirt and stains from the fibres.
Now the cleaning process starts this is done with a carpet cleaning wand, as the wand is pulled towards the technician the steam is applied, then pushed back, this is called the dry stroke, if the carpets are heavily soiled or haven’t been cleaned in some time, then a double pass maybe needed.
After the cleaning to get the carpet to dry as fast as possible a grooming of the carpet fibres is required, this will help the pile to stand up and allow air to move through the carpets fibres easily. If the correct amount of steam is applied and the equipment used is in good working order the drying time would be between 1-5 hours, this will depend on how heavily stained the carpets were to start with.
If the steam cleaning process has been done with a portable carpet cleaning machine then the holding tank will have to be emptied at the end of the job, this is usually put onto a garden bed or grassed area, not onto a pathway or storm water drain. If a truck mounted carpet cleaning machine was used, then the holding tank in the back of the van would hold this until emptied.
