How to approach businesses for waterless washes

[Steadfast detailing]

I was thinking of filling in the time I have between doing high paying paint correction and paint protection jobs by going around to small businesses and offering mobile waterless washes on their cars parked in the parking lot or garage (wherever it may be).

How should I approach this? Was thinking that would I approach a business and asking to speak to the manager/boss etc with the following:

1. Introduce myself, my business and where I'm from. Hand them a business card.
2. Explain that I'm approaching businesses and inquiring whether they want their car conveniently cleaned whilst they are working and then they can go home in a nice clean shiny car.
3. If they agree, I will ask what car so I can quote them a price based on car size, let them know that there will be an extra fee for vehicles exceptionally dirty.
4. Ask them to come out and show me their car.
5. Get to work.

Should I collect money afterwards when the work is done? I mean it's not like they are going to cheat me, I know where they work after all haha.

What do you guys think of this approach? Any changes I should make, any tips or advice? Thanks.

What do you mean by waterless wash? Can you share your washing and cleaning process? Can you also share what you charge for an exterior waterless wash?

I'll be using a waterless solution (duragloss rinseless, ONR, etc) with microfibre towels.

Will probably start my prices from $70. I'm in Australia.

You will be doing Rinseless Washes correct? You will be using a bucket? You will charge $70 (American dollars) for exterior only wash?

Waterless wash but with ONR and other rinseless or dedicated shampoos (haven't decided yet, not too concerned with this atm). No bucket. I said I'm from Australia, so Australian dollars. Google converts that to USD $51.

Im no professional but i dont think you can use onr as a waterless wash. You can use it as a QD but in my experience its not the same as waterless wash.

I think it's fine for lightly soiled cars but any more than that no. I'm not really fussed about what product I'm using because I can get all that later. Just trying to work out my approach.

Thanks for the tips.

The reason why everyone uses ONR as waterless wash is because it's so economical. Some RTU waterless wash products cost $15 to $20 for a 24 oz bottle. You can make 256 gallons of RTU waterless wash with ONR for $40

Is there a reputable waterless wash that's available in bulk sizes?
