Flex works good. And a grout brush. If its real bad I'll hit it with the uph tool. Slow but does a better job than the wand.

A heavy liquid prespray with butyl and trypolyphosphate, or tetrasodium phosphate (liquid ultrapac, or Firewater) in it gives me the best results before I have to pull out any gel and a brush.

We see a lot of this type of soiling up here in the north with the heating season.
We never promised that we are going to get it all out because you cannot usually get it all out.

Also you have to be worried about how much paint you're going to take off those baseboards trying to get up close and personal. There are times we refuse to try and do more than prespray... heavy try to get up close safely and sometime just on your hands and knees with a microfiber rag trying to clean out the edges a little bit too.

Don't promise you are going to get those stains

The type and degree of filtration soiling seems to vary from different locations. I often hear of it not being a problem at all, to being something uncleanable. Here, except for relatively new carpets, it verges on the uncleanable most of the time. One of the worst I have ever dealt with was in a brand new condo building with white nylon carpets in all of the suites. No one had lived in the suites, yet there were filtration lines up to 8 inches wide. The building had a couple of obvious ventilation problems. First was the elevators weren't vented properly. By the time an elevator reached the 20th floor or above, it displaced a ton of air. Enough to blow a ladies dress over her head, Marilyn Monroe style. The second problem was that they installed individual heat pumps in every suite. The filtration was much worse bordering the mechanical rooms. Our job was to improve it enough to allow them to complete a sale. We used a ton of filter out type products and scrub brushes and edging tools. Looked good for about a week or 2 then started coming back. One of the problems with the filter out products seems to be residue that is very hard to rinse out. Generates a lot of foam which is a real issue for portables especially. Most of the time now, we just use our regular prespray and a pmf edging tool. If it doesn't come out, too bad. You can sometimes see the tool marks of the installers as well as where they stapled the carpet to the tack less. Poor installation techniques.

Kleenrite BlackOut Grout Brush and a old 4 '' SteamWay Stair Tool. I have a Crevice Tool but it doesn't flush very good and it only covers about a 1/4-1/2 inch out from the wall. Many times the filtration soil is wider than the crevice tool so a 4'' stair tool works better. Yes it means getting on your knees but it just does a better job and you can move faster. I run the side of the stair tool along the baseboards. I get good results and do charge extra for this work. BlackOut rinses easier than the gel type spotters for soil filtration.
I use this method mostly in the extreme cases.

It works great for tight spots. Between beds and dressers or cleaning the edge of area rugs. It puts out a lot of solution and works great for flushing/cleaning soil filtration. I don't use it for stairs because it's too small and slow.

yowsers if I could get that I'd be trying to upsell everytime I saw it 🤔

mind sounds like you deal with some stubborn stuff compared to me
Sounds like more than it is. Not every wall has it. Maybe $20-$30 per average room on top of the regular cost. That includes spray/scrub/extract with edging tool. Like Mikey says, it's coming right back. I discourage most but there some where it needs to make a difference, either for a sale or an inspection.

if I have to use anything stronger than regular prespray, I tape the wood trim off with painters tape
just like I do with any wood floor that is in contact with carpet that I will be cleaning.

Good idea to turn your pressure down. Try the pmf gum blaster as well. It uses a flood jet which you can turn in towards the wall a little. Lots of power and a little wider.
