We get regular calls from carpet and upholstery cleaners and restoration contractors who have had call backs from their customers regarding deodorisation. A general deodoriser cannot be formulated to tackle every task properly, nor does one technique suit all situations. Hence it is necessary to know which products to use and how to use them in whatever situation arises. Firstly it is important to identify the source of the odour; is it in the carpet or upholstery, in the framework or the flooring or is it airborne? Wherever the source is, the best result will be obtained by targeting the source and using the appropriate treatment. Ask the customer good questions and consider the answers carefully; hopefully that will be enough but also use as many of your senses as possible to help you. Look for colour or shade changes in textiles, use your sense of smell (adding moisture often reenergizes odour), sight and even touch if it is appropriate. Our industry is full of helpful, time saving tools, moisture detectors can help for conductive liquids, UV torches can help for urine, scrapers and spotting spatulas can help for food and protein spillages. It makes good sense to use them. Remove as much of the source of the odour as possible. It sounds obvious but is often neglected; for example, if you need to deodorise a car that belongs to a heavy smoker your first task is to remove and clean the ash tray. When removing the source, start by using mechanical methods if you can, scrape, freeze, vacuum etc. Then remove the components that can be dissolved in liquids, whether water soluble or dry solvent soluble. If you are using detergent products, choose those designed to both emulsify and suspend for extended periods, such as Pre-sprays and Traffic Lane Cleaners. Enzyme rich products like Enz-All will digest food related soils and suspend them, breaking them down in preparation for extraction. Solvent based products such as Smoke-Solv are great for fuel oil spillages; it is always best to choose something appropriate. In terms of techniques consider the different extraction methods available, hot water extraction is usually more effective than bonnet or dry compound when you are faced with food or protein related odours. When it comes to deodorisation it is critical to select the right product to get the best result in the time available. Urine Contamination Treatment is formulated differently to Kill Odor, Air Neutraliser is formulated differently to Kill Odor Plus, so it is wise to choose an appropriate product and, if you need help, ask Chemspec Europe or a knowledgeable distributor. Whenever deodorising, make sure the right product makes contact with as much of the source of the odour as possible and in sufficient quantity to do an effective job. In many cases thorough saturation may be needed combined with extended dwell time, you can’t expect a severely urine damaged carpet to be effectively deodorised with a few pumps of a trigger sprayer. Even when no unpleasant odours exist, it is good practise to use a deodoriser as the customer will be much happier with any cleaning job when their sense of smell tells them that the carpet or furniture ‘smells’ clean as well looking it.
