Sick glass? Maybe this will work for you.

[juxtaposed]

6. How to clean sick glass, sick glass to me is oxidation, corrosion of the glass itself.

Not lime or water deposits.

The only thing that I've found and use that works is "Whink" with Hydrofluoric Acid this is what many bottle collectors use as a last resort.
Hydrofluoric Acid will dissolve and etch the glass, so it should be experimented with on things that aren't worth anything.
A less invasive way is to use a tumbler with copper BB's.

10. STABILITY AND REACTIVITY

Stability Stable under recommended storage conditions

Incompatible Products Glass, concrete and other silicone materials. Carbonates, sulfides and cyanides (yields toxic
gases). Alkalies and oxides (cause violent exothermic reactions). Common metals (yield
Hydrogen Gas, fire and explosive reactive hazard). Corrosive to many materials (includes
leather and many organics). Water added to product yields heat and violent reaction.

Conditions to Avoid Moisture, humidity, heat, flame, ignition sources and incompatibles.

Hazardous Decomposition Products Emits sulfur oxide gases under fire conditions and in contact with water.

Hazardous Reactions Reacts violently with water, metals, alkalies, oxides, carbonates, sulfides, cyanides, glass,
concrete and other silicones.

Hazardous Polymerization Hazardous polymerization will not occur.
