That is great, but I wouldn't recommend anyone use a product that specifically says not to use on glass. But that is just me. Good luck with the cleaning and foggy spots.
Look up cleaning lab glass if you want to know how its properly done.
Oxiclean is alkaline and alkaline solutions corrode glass.
and TSP is not recommend for use on glass
