Bottom to top high pressure is needed to make sure all areas are hit. A thorough rinsing will go after. You can't do an initial high pressure cleaning from top to bottom, because the rinse water wil clear LOOSE soil and leave a "clean enough" appearance fooling you into skipping over areas. What is left behind is a faint layer of dirt that can only be cleaned with high pressure. When it dries your end product will look horrible. This also increases "dwell time" of cleaning chemicals, giving them time to break up the dirt, rather than washing it all away at once.
I find it strange that foreigners like to wash from the bottom up. Then when they wash from the top, the dirt falls down where it was already cleaned. Here in Brazil we wash from the top down so the dirt doesn't fall back down where it was already cleaned (Use Google Translate to write this)
Top down.. did this for 6 months and pulled me shoulder out doing a stained asf curtain side.. high pressure water gets the top layer of but leaves streaks of dirt.. straight soap, not concentrated. One section at a time.. otherwise it dries up... yeah takes forever but that's the way to get it white, unless the tanks pitted from emulsion black shit being on too long and causing hairline cracks underneath near the King nipple. And check the aluminium welds Try doing emultion tankers ahh.. them gantrys
The reason for washing from the bottom up is simple. The chemicals used to clean equipment break up the dirt and loosen it from the paint surface. So if you wash from the top down after applying the chemical, you tube away the chemical. And therfore the high pressure won't be able to take off the dirt. So you start from the bottom and go up. This will ensure that the duty will stay loose and the high pressure will take it off. If you have done this for a living, the chemical makers will state this on their products.
What does it mean if it is washed up or down? Isn't it more interesting to know about the waste that is washed off, where it ends up. Does it end up in an oil separator, or does it just run into the sewer or onto the site
I think it's to make sure every inch is pressure washed and not half washed by the fallen water. This way you keep seeing the dirt all the way up. A final rincing is necessary though.

If you think about it basically you're using twice as much water as as you really need to that doesn't make any sense😂😂😂😂
@@thomasreyes2857I think he never washed a single car in his entire life 😂😂😂
I want that job
Let me see let me start from the bottom up. That should work and I'll save some water that way😮😢😂
they must get paid hourly??? lol
I noticed the same.
Who washes a vehicle from bottom to top?
I do even under the wheel arches

Bottom to top wow they must be stupid cause all the dirt goes right over your clean area
u r supposed to go from the top down.
No because you are rinsing off the cleaning solution if you wash from the top down over
Trasporting??? 😂 TRANSPORTING!
Not effective
Too little water, weak pressure washing.
