Dear Friends
Two-and-a-half years ago when we bought our van, I stumbled upon this site (and was about US$4K richer), and Chemical Guys's poorly named but highly lauded air freshener Stripper Scent was the crowd favorite.
That's the only air freshener I've used since then because I love the smell.
I go through periods of spraying our van every day with this stuff, and, not surprisingly, that's what our van smells like even when I haven't sprayed it in a week or so.
Just keep using it. Your interiors will begin soaking this in and the smell will begin to have greater durability.
