Let’s get one thing straight: that white film is not soap scum. It’s much more dramatic. It’s actually hard water scale—a mineral deposit of calcium and carbonates that got baked onto your dishes like a bad tan.
Your dishwasher is basically a hot, violent rainstorm. If the water is hard (meaning it’s full of minerals), the heat evaporates the water, leaving those minerals standing on your plates like awkward party guests who refuse to leave. Think of it as nature’s glitter, but way less fun and way more annoying.

Here’s a wild fact: your detergent might actually be part of the problem. Yes, you heard me. The hero is sometimes the villain. If you use too much detergent, or if the water is too cold, the detergent doesn’t dissolve fully, and it leaves a phosphate-based grey haze.
But wait—there’s a third suspect, and it’s a real jerk. Etching. This is when the glass itself gets eaten away by harsh detergents and hot water, creating a permanent scar. It looks like residue, but it’s actually a little piece of your soul... and also the glass’s surface. Once etched, there’s no going back.
