Best method to prevent HW from drying

Chemical/Chemistry

I see three options:

A. Apply more HW

B. Apply a mist to the surface from a distance

C. Increase SH concentration to reduced dwell time.

I know this is a basic question, but I have been wondering about it a lot lately. All of these options work but I would like to hear from some experienced professionals as to which of these or other methods are preferred and why.

Thanks

If the surface you are cleaning is in the sun, you can pre-wet it to cool it down. Sometimes when I do that I actually see steam coming off the siding on the first pre-wet, then another pre-wet, and then apply HW mix a little stronger, for down streaming that might mean two soap applications.

It all depends on the weather and how sunny it is. Pre wet the surface to start and while your learning just do one side at a time to watch your dwell times after applied.

I come back and hit it with water …just enough to keep it from drying
