Dr. Bronner's Sal Suds for interiors- a good option on customer's cars?

Hey, folks. A friend and I starting up a small interior detailing gig and we're pretty new to this. For our own health and the health of the customer, we're aiming to use cleaning products that have natural ingredients as much as possible. In light of this, I've done some research specifically on Dr. Bronner's Sal Suds. I haven't found too much information on Google but some people have said that they've used it on the interior of their Teslas in the past. Dr. Bronner's themselves even wrote up a whole post about how to make all-purpose spray for interiors: https://www.lisabronner.com/green-cleaning-car-interiors-with-dr-bronners/

This all-purpose spray would be used on anything Griot's or what any other all-purpose spray would be used on. I'm even thinking of using a small amount in our carpet extracting machine solution to clean carpet mats, upholstery, and what not.

Anyway, anyone have some ideas or experience with this? Does it sound like a safe option? Thanks! 🚗
