You know that smog line under the door? ( I call it smog line lol) but its from forced air going through the carpet and getting filtered leaving a dark line.....I generally just prespray and they lighten but lately I havent had much luck getting these out. So, whats the game guys?

I actually like FSR from Pro's Choice for those filtration lines and a stiff brush for auto interiors. It wins out most of the time.

It's called filtration soils, someone that used to post here a while back will always recommend fels naptha, he swears by it, I usually spray with my pre sprays heavy and scrub, most of the time they lighten up a lot, I always set the customer's expectations regarding those, there's no way I'm scrubbing every filtration lines along the walls throughout the house even if they're paying me extra for them, it just takes way too long and that's a lot of wear and tear on my equipments and my body.

There shouldn't be filtration lines all over the house unless the hvac system is designed incorrectly. Around here, it might only be the thresholds and floor ducts in a couple of rooms.

We get them all the way around the room all the time.
I spray them with my "shoot from the hip" formula that works as good as Fles but I don't have to get down and rub a bar of soap on anything. Don't get me wrong I have some fels because about once a month my hip shot formula wont cut it.

And for your next question... I mix quart a spray bottle with prespray at 4X the strength for normal prespaying. I learned this trick once when I tipped over my inline sprayer and the concentrated formula got on the carpet and it got everything so clean I had a devil of a time matching it.
