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)
The explanation for this is simple. The main dirt is in the lower area (the chassis) of the truck. Therefore, cleaning is carried out in 4 steps. Firstly, wet the entire vehicle. Secondly, clean the lower area intensively, including stubborn areas by hand with a brush or broom. Thirdly, clean the upper area. Fourthly, rinse everything again. (Plus fifthly) Each washing, especially high pressure washing, removes all combinations of dirt and oil. But moving or turning parts need clear oiling or grease lubrication. So the entire truck has to be re-lubricated after each washing. Do it yourself or have it done in a workshop. (Used Google Translate to answer this)
@@helmutwernerkrebs5878 Here in Brazil, trucks are washed from top to bottom and they come out very clean. It simply doesn't make sense to wash the bottom and then the top so that the dirt from the top falls down where it was already cleaned. That's rework. Time is money. The rule of least effort. The truck will be clean one way or another, but your method is more work and takes more time. Here in Brazil, truck lubrication is done at gas stations. I wish you all the best...
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.
From the US, my son is a truck driver & he told me how much it cost to get his truck & trailer washed. I thought it was expensive but after seeing this I can see why it costs what it does.
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.

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
Why in the world would you start at the bottom? Start at the highest point, working your way down, and let gravity help you to dislodge and remove caked on petrochemicals! This method makes no sense, as you'll have to constantly re-wash parts you've already cleaned.
Asphalt oil is notoriously unforgiving when it comes to cleaning a paint or metal surface. Often requires multiple applications of citrus oil, heat, or scraping to get the thick layers off. Especially tack

I use a commerical steam cleaner, soap and final wash with a commercial pressurized water cleaner.

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 😂😂😂
Yes sir now that's how you clean a truck 👍👍👍👍
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
It allows you to see what hasn’t been washed, if you start at the top the water running down the truck could hide dirt!!!

This goes for Cars as well - example the door mechanics.

How about a cattle stock truck?
now I know why to wash from bottom up
Why not start @the top and work down?😜😜😜😜
Smart people was from top to bottom.
I want that job
Compresed modulated off and on filer . Silicaceous.
Your intro : it's NOT a Scania, it's a Mercedes 1843 ! ! ! !
You need a foam cannon, saves time, and you don't have to work so hard! Amazon sells them!
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.
It shouldn't matter if you wash it top or bottom it's getting clean
Trasporting??? 😂 TRANSPORTING!
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
Its like $60 for a truck wash
Scratless piece of junk, lol and you clean from bottom to top that cracked me up!🤣🤣🤣

Völlig unkoordiniert die Reinigung
Too little water, weak pressure washing.
Not effective

More effective than your comment!
Boring
HA HA HA Wrong english on the side stating INFLAMMABLE. Obviously special bitumen that doesn't burn
Irritating watching this! You can tell he's never washed anything in his life! TOP TO BOTTOM!
