Carpet Stain and Spot treatment is the attempted removal of spillages or stubborn dirt that has not been removed through ordinary vacuum cleaning and carpet cleaning. The process involves the removal of any solids or oils with solvent-based spot-removal products.
If this first step does not remove the spot then the carpet is classified as damaged and only a colour-dying or lightening treatment would be able to restore the colour of the carpet. This second process is called restoration and due to the risk of not being able to restore a carpet 100%, it will not be undertaken without written consent from the customer.
Tea, coffee, wine and turmeric stains will most likely not be removed through solvent-based treatment. Any chemicals that have been applied to the carpet before our technician arrives may have a lightening effect and it might be possible, that once water is applied to the spot, that the carpet will lighten. This would not have been the fault of the carpet cleaning technician. An example of a successful colour changing procedure, undertaken by an experienced carpet cleaning technician, is shown in this picture below. A customer had used a Rug Doctor carpet cleaning machine to clean their viscose rug and the cleaning solution had soaked through the pile down to the backing which consisted of untreated natural fibre. The tannins within the fibre were released and the brown colouring slowly wicked through the pile toward the surface. Viscose is often made from bamboo or rolled cotton and behaves like paper when wet. Trying to clean it would be as easy as trying to remove ink from a page. The only procedure would be to use a colour-changing method, and in this case, hi-lighting.
