Understanding Stains and How to Remove Them
The pH scale helps us understand how alkaline or acidic all water-based substances are. Based on this information, DR Floor Care’s specialist restorers can then apply the correct mixture of chemicals to these stains to vastly enhance restoration results.
At the very acidic end of the scale, citrus fruit and Coca Cola for instance, understanding their chemical makeup means Restorers will apply the likes of a browning treatment and hydrogen peroxide rather than other pre-made solutions which could result in further damage.
Around the middle range, 7 on the pH scale and therefore relatively neutral, the likes of beer, milk, blood and eggs require less concentrated or abrasive chemicals to help return the surface to pre-loss condition.
Substances registering high in alkalinity such as bleach, are counteracted by the likes of tile cleaners, chlorinated detergent and floor stripper.
Of course, the sooner a floor surface, such as carpet, is attended to by our Technicians and remediation begins, the greater likelihood for success. Old stains are notoriously difficult to remove and even if this part of the process is successful, often white patches are left behind and cannot always be colour matched with their neighbouring fibres.
To successfully remove combination soils, that is a mixture of contaminants is to first identify which of the three main types they are:
- Organic: body oils and fats, animal waste and bacteria, moulds and plants;
- In-organic soils: lime scale, minerals, rust and efflorescence;
- Oils & grease (which contain no water): motor and cooking oils; waxes & resins, gum and bitumen, ink and oil-based paints.
Organics are dealt with by using alkaline chemicals, in-organics by acid and oils/greases are best treated with solvents.
