I use UITG and love it! I recently wiped down my interior with 1Z and the dash board looked "blotchy" after. I didn't use a lot of product and wiped with dry micro fiber after wiping down with a " spritzed " micro fiber . I normally use a micro spritzed with distiller water to wipe down my interior as its already protected with uigp. I was just looking for a little more " clean ". Thank you
