"Spot Free Rinse" - Is it safe?

[R A W L S]

I've got a 2011 jet black M3. I've been using the "spot free" rinse at my local do-it-yourself carwash. It's been working really well. I don't towel dry the car, just drive away and it dries without a single spot. I'm loving the stuff. Is it OK to use or will it eventually burn holes in my car panels? Thanks.

It's probably just deionized water or some other process that takes out the sediment. Should be fine.

I think some spot free rinse have silicone in it. Not sure how that affects the paint in the long term.

I do the exact same thing with the exact same color. But after a day or so I wipe the car down With a Quik Wax Detailer product for that just Waxed look.
Oh yeah, Don't use the brush from those car wash places. Bring a sponge and use it instead. The brush wil cause fine lines in the clear coat.

Should be safe. Th unit I have just removes undissolved solids from the water. It has to be re-charged (new filter pellets) every several washes.
