Won’t lie, would kick in my OCD. But, KC is a meh product, it’s more of a “topper” than a cleaner. Try using something like KC Green Star or Pol Star as an interior cleaner. Can get away using it 10:1 with no problems, though some will use it 15:1-20:1. If you want something that’s already ready to use, Armor Detail Piet is good, along with Gyeon Purify Interior (odorless). Have a new one to try coming in, so can’t give any thoughts on that one.
