Q.Can filtration soiling lines be removed? How do you clean these? Phil.
A.Hi- Phil-

The filtration lines are caused by air movement- where air is moving between the inside and outside, wherever there is a gap between the floor and walls. Most carpet cleaners spend some time removing these, along with the rest of the soils present.

I have and use professionally a special brush for this purpose, as well as a special narrow steam cleaning tool, only 1/2 inch wide, by 2 inches long.

To prevent these filtration soil lines from forming, once they are removed, the carpet must be lifted, and the gaps caulked, to keep the air from flowing through the gaps. If you are going to do this work, you will also need to refasten the carpet when the caulking is dry, about 24 hours curing time. It is a major task, and most folks prefer to just deal with the filtration soil as it occurs. If you elect to have the sealing done professionally, it may cost several hundred dollars, but that is the best answer.

On my web site is the brush for sale, and I also sell some cleaner that is very effective for removing these soils. The soils are the burned petroleum by-products of combustion, and are basically soot. In the cleaning trade, we refer to them as soot lines. This is why most readily available cleaning products have little or no effect on them.

I hope this answers your question. If you have others. please feel free to ask, anytime.
