Cleaning carpets in general can be difficult as the cleaner firstly needs to identify the different fibres before an attempt is made to clean the carpet stain. In other words, link the chemicals (carpet detergents) used on the different fibre groups. Secondly, trying to identify possible carpet stains and soiling residue that remains in the carpet. It certainly makes any cleaning exercise that much easier once we understand all the factors regarding carpets and soiling.
Problem Stains
In the above picture one can clearly see the problem on the carpets. Points were made to outline the possible causes for these stains:
Tea and Coffee
Food Spills
Chemicals
With any carpet stain time is one of the most important factors. I consider a carpet stain permanent, if not removed or recovered within 24 hours. Looking at the concerned areas, it is quite clear that the carpet stains are a result from coffee and tea spill at the work station. We all agreed that this point was the closest conclusion.
