Anyone here currently doing this? There is a little bit of info in past years.
I can figure out detergent, pricing, and waste water. Any other tips to think about. Psi? Etc…
There is a dealership looking for service.
Also, DI rinse. Tank with delivery system? What size tank? Separate wand? How would you set that up? I have an idea but interested in your thoughts.
Im not going to have a big buffer tank on my trailer (30 or 50gal).
Had a friend look into it for a few days but found out it’s not worth his time based on the pay. In our area (DFW) car lots are worth about .75 per unit. They are on about a 10 day schedule. They will drop you in a heatbeat if somebody wants to do it for a nickle less. No soap is used just a blow job and a wipe down with a chamois to get the dust, bird poop and pollen off. No recovery needed as your just squirting water.
I wouldn’t be over 2k psi at the gun and I’d work a lil 12" lance

Had a dealership guy call and ask what I would charge biweekly last fall. Said his last guy retired. I asked how much time it took his last guy. He said a full day to do all cars in the lot. I didn’t even ask how many cars. Told him all day costs $1200.
I think I heard him fall out of his chair. He said the last guy did it for $60/day. Then I fell out of my chair. Told him I’ll stick to houses and he should call KC Wash Pros. They’re the fleet folks in the area, but he should probably buckle in because he’s not going to like their number either if the last guy charged $60.

Lol $60/day on what planet is that worth anyone’s time. No wonder the last guy “retired”.

It was $1/car. Like dperez said that’s about the going rate.
Seems like you’d have to have about 1000 lined up and able to clear them all in a single day to make any money. Definitely doesn’t sound like something I’d want to try.

Or you have to do a car every 30 seconds, less really including travel time to different dealerships, for it to be worth it at all.
That actually sounds worse than cleaning gutters! No thanks! Haha

He forgot to tell you the guy retired in 1962!

Talked to another guy at a dealership. He thought the guys were getting $1 per car. No soap. No spot free rinse. Just blowing them off.
I think $2 car would be my minimum. Would need a big supply tank too. 2 guys. 1 washes. 1 rinses.
There’s a guy on YouTube who’s got it going on.
That whole scheme sounds terrible. AMD the headache of god forbid something happened to a car like a dent or scratch…they’d try to hang you out to dry lickity-split

Just doing research and came across this thread.
In 2021, $1 a car on most lots at a new dealerships might get you $15-20! LOL.
Strange times.
How do you fill up with RO/DI water? I have a xero pure system but would imagine it takes a loooong time to fill up my tank with it. I’m doing a trial run of 90 car lot soon.
I’d use a 1 cu\ft di tank or multiple 1 cuft connected in series if it’s a lot of water
Thanks for the response Jordie. Last year I bought a xero pure package and loved it, that’s the only reason I’ve been thinking about this cause if my xero had a high enough flow I could just fill my tank with it plugged into the source basically.
My main concern is the cost of the filters. We use around 200 gallons of water per location (5 total), and the water here in north Texas is unfortunately pretty hard usually 250+ tds
Based on the chart of that tank, we can expect around 1,500 gallons of pure water, which would get us through about 50% of the week 
do I give up my hopes of a mobile fill up solution?
I sold an old GX390 to a guy who claimed this type of work was his primary income. He said he started over 25 years ago and, since he was “the only man in the game back then,” he’s now the go-to person for all the dealerships in the area. According to him, he exclusively cleans for high-end dealerships and delegates the rest to people he’s “training”.
He mentioned building his own “spot-free water system,” which I assume is some kind of deionization system, though he didn’t provide details. He said he would send me a link and photos of it but never followed through. He also claimed to make nearly $20,000 a month doing this, the numbers didn’t quite add up to me. 
I forgot to mention the zero or outputs about .5gpm.
DI tank outputs about 1gpm.
I’d love to see his system. I can’t think of a way to solve this problem. This 1 contract I have is $8,000/mo revenue though. If you can get high flow pure water to fill your tank I imagine you could make a fortune anywhere. I was shocked I couldn’t find any high flow filter for under $20k. What I see for $20k+ I’m not even sure if it’s usable for this case.
