that's not all that bad, Big Slim
Does anyone use or like a crevice wand? I might buy an internal jet one that comes with a little rubber boot on the end for possibly tile cleaning.
but ive been putting it off cause no one seems to mention them.
No one mentions them cause they're one of those tools that gets bought, used once or twice and then gets buried in the corner of the garage with all the other useless tools
crevice tool isn't what you need, Joel.
4" to 6" hand tools work best on the most tenacious filtsoil
4" PMF enclosed jet (not "internal" jet) is a great one due to it's concentrated mega flush floodjet .
if you use a TM, be cautious of jet distortion though cause you may need to turn down the PSI for some carpet types like dense Saxony or cheap builders grade cut pile
After a good vac, (cause often it's pi55 poor housekeeping and not true filtsoil) we hammer it with strong butyl pre-sprays spiked with oxy, rub in some fels, add some "Florsheim" agitation and let it dwell
and hell yea we charge extra when it's severe and requires more than nuking ....and "hands and knees" work is needed
We also advise them whats needed to correct it by caulking at the floor and wall joints ...otherwise it
will return
