Z7 is the best wash for Zaino because it actually revitalizes the polish, not much unlike the REVOstyler. Sorry... too many late-night infomericals at work...
Eagle One and
Meguiar's Gold Class are great store-bought shampoos while I love Blackfire wash to strip off my wax with its pH 9 Tuff-Suds. OG WAW, TW Zymol, and Sonax Gloss are excellent, too!
Oh, P21S is so slick that I slipped on the suds.
