Pittsburgh Humidity Makes Your Carpet Washing Expert's Work Meaningless Within 72 Hours
Pittsburgh, PA carpet cleaners face challenges caused by humidity that don't allow carpets to dry sufficiently and therefore remain susceptible to mold growth within 48 to 72 hours of wet cleaning. With Pittsburgh having an average yearly humidity of 65% to 75%, it will hold moisture and allow for the growth of mold under the carpet after steam cleaning these surfaces.
The Pittsburgh Carpet Washing Chemistry Problem
The issue with getting your carpets cleaned in Pittsburgh is
that hot water extraction (steam cleaning) places a large amount of water into
the carpet backing and pad, which should dry in 6 to 12 hours; however, with
the higher humidity in Pittsburgh, the evaporation process is slowed down
significantly, with carpets taking anywhere from 18 to 36 hours to completely
dry. For this reason, carpets remain damp for the time period that mold spores
begin to germinate.
How Carpet Washing Pittsburgh Requires Industrial Dehumidification
Professional carpet cleaning in humid areas requires that you have
a professional use an industrial dehumidifier running continuously for a period
of 24 hours or more post-cleaning. Most carpet cleaning companies in Pittsburgh
will simply run fans in an attempt to dry the carpets out, but while the fans
do help circulate air they will not do anything to remove the moisture that is
in the air.
Conclusion
When you begin to smell mildew 2-3 days after having your carpets
cleaned, it is not a result of dirt returning to the carpet. It is instead a
result of microbial growth in the carpet backing that was never completely
dried due to the high humidity that is present in Pittsburgh. Therefore, when
you have your carpets cleaned in Pittsburgh make sure you are aware that the
professional part of carpet cleaning in these types of climates is controlling
the moisture, and not just cleaning chemistry.
