He's done a video before on what his normal process looks like, and its always had both the water spritz and WDT, so while annoying he didn't clarify, I'd assume he's still doing WDT in these results.
My completely unscientific guess is its possible that WDT is redundant or solving a different problem, given WDT wouldn't be breaking up much of the static charges between smaller particles, just mechanically separating larger clumps that are visible to the naked eye. Still very keen to see someone rule it in or out because I personally loath WDT first thing in the morning
I can’t stand the majority of YouTubers, but James manages to come across as respectable and genuine. That’s perfectly compatible with him trying to be successful and playing the YouTube game a bit. In his position (and I don’t think he intended to become a ‘YouTuber’), you’d have to be either stupid or utterly uninterested in success not to.
