Applying & Rinsing

I usually pre-wet as well. One of the reasons I pre-wet is to cool a surface down so the chems don't dry too quickly. Hot as heck here in Atlanta in August. I usually apply chems from the bottom up.
 
if your using an x-jet i really dont think it matters since it covers large areas quickly but i still think its wise to apply chems from bottom up. as for prewetting surface i always thought that it would weaken the chems, although i have power washed in the rain with excellent results.
 
Bottom to top (always). On big jobs you can leave marks if it's really dirty and is running down a dry surface, almost like an abrasive.
 
In seven years of full-time/year-round residential washing, I see no difference. Frankly. I wash from side to side, starting at the top, downstreaming my mix. I have never had an issue with chem causing a problem if it dries either. I usually wash all the way around a house, or at least 2 or 3 sides at a time, then rinse from where I ended. No streaks on siding or windows.

Do you apply chems from the bottom up or do you start at top. I've seen people do both, I have never really figured what the difference is.

We wet it down, apply starting at the top and rinse
