Dirt on carpet under door.
Let s start by solving the problem.
This soiling is called filtration soiling because it comes from air passing through the carpet as it is attempting to get through the crack between the carpet and the baseboard or under a closed door.
Dirt is bound to get ground in to a carpet that is walked on regularly even if you take your shoes off before doing so.
All that fuzz mixed in with the dirt in your vacuum cleaner bags is your beautiful carpet headed out the door one bag at a time.
It is often caused by an improperly balanced ventilation system when the volume of air entering a room exceeds the system s capacity to remove air.
However you cannot install indoor outdoor carpeting directly on dirt because the adhesive won t harden on surfaces containing debris.
It filters dirt smoke cooking oil out of the escaping air leaving you with clean air and a dirty carpet.
Over time grinding dirt wears away the fibers too which mats them down and makes them.
It is caused by airflow over and through carpet allowing fine soils to settle on the surface.
Lay the sheets in rows across the dirt floor.
Overlap the bottom of the walls with two inches of the sheet edges raised upward along the wall s surface.
Cover the dirt floor with a layer of 10 mil plastic sheeting to serve as a vapor barrier which will keep moisture from seeping through the dirt and onto your wood floor.

Filtration soil may appear as dark or grayish lines on carpet along walls stairways and under doors.
Vacuuming your carpet regularly at least the highest traffic areas will delay the inevitable but once dirt is pressed into the carpet s fibers it s time to do more than vacuum.
Gaps between the carpet and baseboard trim may be sealed using an expandable foam sealant.
When dirt scratches the fibers it dulls the sheen which is why high traffic areas appear duller than the rest of the carpet.
The carpeting installs quickly on a variety of clean flat surfaces using carpet adhesive or double sided tape.
Indoor outdoor carpet is fade and stain resistant durable and available in a variety of colors.
A carpet under a door or over a crack acts like a filter.
As the air passes through the edge of the carpet pile this microscopic soiling is deposited there hence the term filtration soiling.
