For a QD I use about 3oz IUDJ + gallon water. Like ZL1Mark posted, I use about 2-2.5 oz IUDJ + gallon water for rinseless, but that's probably overkill.
I say "about" because I'm not too precise about it...
I really like the looks of Pinnacle XMT Spray. For cleaning duty, I like PB's Spray and Wipe (feels thicker and slick) but will use UWW more than anything else for just general use But, I like to use scented detail sprays (Mothers Showtime, CG Speed Wipe (old scent)) as well like on jambs.
Yeah, Spray & Wipe holds tight on vertical surfaces. It's not runny and thin, but still wipes away clean. They really nailed the chemistry on that one.
Don't ya love Mothers Showtime scent?
