Detailing Semi-trucks/finishing touches/random questions

Hello, I’m just getting started in the detailing business. I mostly clean semi-trucks. I give them an exterior wash and clean the inside. Fairly basic (no waxing or fine detail stuff). I just got a DI water set-up. That helped with the water spots tremendously. I pay about $55 for the DI tank which gets me anywhere from 300-600 gallons they said. Sound about right? Is there a cheaper way to get DI water?

My main question is for finishing touches. Is there a good product to use while I walk around the truck to catch any mistakes (few water spots, random dirt, grease, etc.)? I was thinking something like a Windex but there might be something better out there.

Also, is there a certain type soap I should be using? I’ve heard something about PH balanced, which will also help with the water spots.

Is there a good way to get the back part of the semi-truck cab? There are lots of hoses, vents, etc. that make it hard to brush.

I’m finding out that time is our biggest enemy and a good set-up is crucial. Any other tips for me would be appreciated. How do you clean semi-trucks that saves time?

Thanks!
