Anyone found a new way to clean up sick glass?

1. I'm not exactly sure what you mean by sick, but I have recently had

unexpected success using chlorine bleach spray cleaner getting cloudiness out of glass when nothing else would do it, not even scrubbing. Soaking is how I've done it. Spray a good amount of the cleaner around the inside of the glass, let it sit, then fill the glass with water and let that sit. I've been surprised how well it works. I imagine you could use just plain chlorine bleach rather than the spray cleaner.
