Desert, wind, and sand

So was talking to a possible client that will need to replace their old window cleaner in the future and he asked if I can service his places down towards the Tri-Cities area in my state. Down there they have a climate that is dry and dusty. So with this possible work in the future I was seeing if the people who service windows in these type of conditions use more or less soap in their window cleaning mixes? Is it just futile to try and get a good mixture because I would believe soap would attract more dirt with all the sand?
Sorry to ask but I couldn’t find it in search anywhere. Any help would be great. Thank you!

I use 4oz of easy glide and 6 oz of dawn 2x per five gallons of water. Seems fine. Its all I’ve ever used but it works and customers seem happy?

No, not soap, but you should invest in the microtiger mops if you don’t use them already. The unger monsoon has the same scrubbing ability as a wet cat and is useless for scrubbing off baked on dirt.

@Trenchfeet. So pretty much just keep doing what I am already using. I was just curious if it attracts more or less dirt.
@JaredAI. I have been using my moreman for the last month and it cuts through almost everything. In fact the blue has been turned to brown more than one occasion
