Hey guys, been trying to battle it out between CarPro inside , Koch Chemie polstar and p&s express interior cleaner. I have p&s at 1:1 , inside at 5:1 and polstar 5:1. Which one would potentially clean better? Also what’s the difference in strength betweeen 10:1 and 5:1 for polstar? Anything you’d be able to visually tell ? Also can express interior cleaner handle Alcantara and fabrics/carpets?
