MULTI I've tried a lot of APCs, but I find Wolf's Chemicals The Multi the most versatile and effective that you can have on your detailing shelf.
It cleans very well and you can play around with its various dilutions while enjoying its amazing smell! For interiors, trims, rims, wheels, exteriors, The Multi can deal with every job everywhere. It's even a fantastic prewash, moreover on waxed cars, thanks to its neutral pH, which makes it totally safe. It's just essential for me now.
