Many customers that I have cleaned, have pointed out that the previous cleaner could not remove those black lines around the baseboards and under closed doors? These black lines are between a quarter of an inch to half inch in width and travel down the length on the wall.

This type of soiling is called Soil filtration. Its the airflow contaminants that are trying to pass through a door or the crack in the wall. This contamination is similar to what you find in your air conditioning filter. Besides keeping your carpet and floors clean, it’s extremely important to get your air conditioning and heating systems cleaned once in a while to make sure that it’s bringing in fresh and clean air. This will help in minimizing the dust and dirt that collects on your indoor floors that you’ll have to clean up. If you are in Clifton, Morristown, or Paramus NJ and ever need heating repair, then call Atlantic Plumbing Heating and Air Conditioning.

As the air passes through the edge of the carpet pile, the microscopic  soiling is deposited there, (hence the term filtration soiling). This build up occurs over a extended period of time and is not noticed until a build up has occurred.

This type of soiling is very difficult to remove because the soil particles  are so fine that they penetrate deep into the carpet pile, sometimes into the backing of the carpet.

Removing this type of soiling is very difficult and requires special cleaning agents to assist in the process.

To help prevent soil filtration, vacuum and wipe the edges of the carpet on a regular basis.
