Back in the day I swore by that cheap, generic glass cleaner from the big box store.
I went through three whole cases of the stuff before realizing it was leaving a haze on every tempered shower door, costing me over $300 in callbacks and re-dos before I switched brands.

Man, that whole chemical reaction thing makes so much sense now. It reminds me of my neighbor who used a vinegar mix on his new car windows for months, swore it was streak free. We finally looked in the right light and the whole thing had this weird, cloudy fingerprint that wouldn't budge. He had to get a detailer to use some special paste on it, took hours.

My detailer friend uses a cerium oxide polish on a foam pad for that haze, works every time.

That haze you saw on the tempered glass is the real killer. It's not just a bad clean, it's a chemical reaction. The cheap stuff often has ammonia or other harsh junk that reacts with the hard water minerals already baked into the glass from the factory tempering process. You're basically etching a permanent film into the surface. Once that happens, no amount of the good cleaner will ever get it off. You'd need a professional polish with a buffer and cerium oxide, which costs way more than your callbacks.
