The dangers of Dawn Dish Soap: https://www.physics.purdue.edu/primelab/safety/MSDS/Dawn Liquid Detergent.pdf
OMG it's up to 30% SLS's!!! This is a very reasonable SDS as at the bottom of the section where it lists the "poisons", it says this: These substances are listed because in their pure bulk form they meet the OSHA and/or WHMIS definition of
hazardous. Any hazards associated with this finished product are listed in Section II of this MSDS.
Section II says this: Ingestion: Ingestion may cause transient gastrointestinal irritation.
Eye Contact: May cause mild, transient irritation.
Skin: Transient irritation with prolonged exposure to concentrated material.
Inhalation: N/A
I started to watch the Nemesis video to see if it had SLS in it, I had to stop when he got to the criticism of PDMS. Silicones are the basis for virtually every car wax, sealant and dressing. Before he got to that he said that Amines, C10-16, alkyldimethyl, N-oxides are the main ingredient in Dawn, which only makes up 5% max vs. the up to 30% SLS's as you can see from the SDS.
He does talk like a chemist, but not one that's ever been in the real world. He says the Dawn ingredient needs to be rinsed because otherwise it will etch. The Nemesis SDS says it's in Nemesis at a rate of 1-5%, and that Nemesis is 40-55% water. So just in the bottle, that ingredient is already diluted at least 1:8, and then I'm going to dilute that again at 1:256...I'd argue that your "rinseless" wash already has plenty of water in it to "rinse" that ingredient off.
I'll shut up now, because we've reached the end of civilization, where some random yo-yo on YouTube, that we don't know anything about, AT ALL, can make us believe what he's saying, and that goes for me too (I'm just some random yo-yo on a car forum). But hey, we all should do our own research, even if we have no knowledge of the subject matter. Some day I'm going to read Tom Nichols' book "The Death of Expertise" if I can find where I put it, I think it's buried under detailing products I bought from listening to yo-yo's on a detailing forum.
