Anyone run a hand car wash?

[J012E]

I have the opportunity to invest in a local hand car wash which is profitable and has the potential to grow.

My only concern before investing is the chemicals/soap/detergent/cleaning liquids used aren't branded and therefore I'm not sure they are up to the standards I want and expect.

Does anyone know of a fairly 'green' commercial grade equipment that is financially viable but not damaging to cars so that I'm not sued later on?

Thanks

Thanks for all the tips, I've seen autosmart elsewhere so will get in touch with local suppliers.
