Sorry for the late reply, however due to scheduling and covid, I only got back to the restaurant 2 weeks ago, and I used the TSP solution, and I’m not sure if it’s because the restaurant hasn’t been open for a few months or is the TSP, but the windows was a lot better to clean thank you very much! There was still a slight haze in them, which I’m unsure if it’s just the glass or something else, however they was a lot better with no blade marks this time.
Thanks for all the replies!
