The primary reason for this phenomenon is the alkaline cleaning residues that are present in the chemicals you use to clean the stains. The dirt is drawn and attracted to this residue and hence the spot or stain keeps showing up at the same place again and again. Owing to the different fabric or materials for the carpet, cleaning is a bit tricky and if you manage to get a stain on it, the task becomes all the more difficult to get that coffee stain off. Our carpet cleaners specialize in pet odor removal, stain removal, application of stain guard protection and deodorizing.
