In another thread someone mentioned filtration soiling. How do agressive do get and what kind of results are you achieving? What tools and what chems work for you?
This is one of things that a lot of carpet cleaners and home owners don't understand. It is coming back. We have many carpet cleaners here charging $2-3 per foot. I had one building years ago that had filtration soiling 8 inches wide in some places. Brand new suites that no one had ever lived in and of course, white carpets. The filtration problem was compounded by their elevators not being vented properly. They would push air up and down the hallways. Every suite also had central heat and air conditioning. The filtration was heaviest along the walls where the heat pump was. We would clean up a suite for showing but in 2 weeks, it would start showing up again.I found that some of the products used for fire restoration worked quite well. Prochem used to have one that was about 11 pH and pink in color.
Short of the most visible and annoying areas, not worth the client's extra money as its coming back.
Maybe in 1950no...filtration lines are caused by the furnace drawing air downward thru poorly sealed wall floor joints
Bob has it exactly right. Where you have excessive filtration lines, you can usually stick your fingers under the wall. Carpets that have a tighter seal under the wall have little or no filtration. What some people have done in the past, is to seal the gap between the floor and wall with expanding foam. When cured, just cut it enough to tuck the carpet in.Maybe in 1950
I always liked the filtration jobs that needed a restretch.
Stretch, trim, done. Unless they were unusually wide.
Sure, primary cause is air pollution. The worse the filtration lines are, the worse air you are breathing.Candles can cause it too
Idiots
...and don't burn candles.Change the damn filter in the dam-azz furnace. .....
