To be completely off topic, glasses are amorphous solids. There is a fundamental structural divide between amorphous solids (including glasses) and crystalline solids. Structurally, glasses are similar to liquids, but that doesn't mean they are liquid. Dave

There are some risks that need to be addressed. Acid residue will eat through the paint and steel. Look under your battery to see what Sulfuric acid does. If strong acids are used, do not let any get under the chrome aroun!
d the
window and neutralize the acid with something like baking soda to prevent corrosion of paint and steel. Another useful acid is phosphoric acid (naval jelly) This converts red rust into black rust really well. It also leaves an intermetalic coating on the steel that paint really adheres to. CLR is basically Phosphoric acid. Phosphoric acid residue attacks paint and steel so it also needs to be neutralized. By the way, Coca Cola has a ton of phosphoric acid in it. Put some baby teeth in Coke for a few days and they will disappear or crumble. Vinegar will remove the white haze somewhat. Acetic acid is slow acting but with some elbow grease it will work. Acetic acid takes longer but will attack paint and steel, so neutralize. Glass is a liquid. Glass seems solid, but the molecules move around slowly (meeting the definition of a liquid). Checkout old glass in museums and the bottom will be thicker than the top because of sagging over time. Because glass molecules move around, some of the calcium buildup may be entrained in the glass surface. This is where glass polishing kits help remove the top surface of the glass. The result is clear windows. Be careful to not generate he!

. . . It appears that this ?film? was left there by leaves and various crap, as the car sat outside for years. It is NOT delamination of the glass ? it most definitely is on the outside. It looks like whitish, frosty stuff? almost like what it would look like if the glass had been sandblasted. It?s really strange, careful work with a razor blade will remove some of it, but it?s very slow and tedious. In some areas, the razor blade won?t even remove it. Has anyone experienced anything like this and come up with a solution for getting rid of this crap ? *************************************************************
