Polished glass with blue pad and 205, wiped it down with IPA 15%
Applied Optimum Glass and its been at least 2 years and it is still perfect.
Also purchased a product called 511 impregnator at Home Depot. After new tiles and grout, applied to grout and its perfect as well. Seals out all the dirt and makes cleaning a breeze. Only works on new or perfectly cleaned surface or it will lock in the dirt.
