As wonderful a product as Zaino is, the MF beliefs are a 180 degree opposite, dark age mentality.
I would only assume that maybe the literature is simply dated; speaking about first generation MF technology. If not, the company is clueless about microfiber as evidence by 98% of the chronic Zaino users who use MF's and are left with stunning results (not to mention the rest of us who use MF's for sealant removal of other brands).
