We only use WoolSafe approved products to clean and rinse carpets and furnishings. For stains that cannot be removed with Woolsafe products, we resort to stronger cleaning solutions which must be rinsed out thoroughly before the rest of the carpet or upholstery is cleaned.
We begin by using solvent-based solutions (enzymes that break down food proteins or solvents that can remove shoe polish or make-up oils), and if this does not work, we conclude that the stain has damaged the carpet by seeping into the fibre cuticles. Examples of such stains are rust spots, tannin from tea spillages or food-colouring. Before using colour-changing products we first obtain approval from our customer. These last-resort products are mild but deep-cleaning, and each application takes about 15 minutes before any change is seen, which is why we may charge a little extra.
The second phase of the stain removal process is only applied in extreme cases, removing the stain from the wool fibres might also remove the wool’s dye and the area could end up being lighter than the rest of the carpet / upholstery. Keep in mind that acidic stains such as urine and vomit may have already lightened the carpet fibres prior to any removal attempts.
We have a range of professional carpet cleaning pre-sprays and stain-removal solutions that break down a variety of heavy soiling, grease, and staining. Most pre-sprays benefit from a short dwell time of around 5 to 15 minutes. Carpet fibres are sensitive to differing pH of solutions and the pre-inspection would have already identified the carpet cleaning solutions for each room.
