Hazy glass

[debbiej]

I got a used rear hatch to replace my damaged one. The parts van was diesel. There is a film or haze on the glass that I cannot remove. Have tried windex, straight vinegar, alcohol, and a number of automotive cleaning products. Stuff like decal remover, glass polish, etc. have had a little success with cerama brute, a glass stove top cleaner, but it is still a foggy mess. It isn't sticky, or greasy, but more like a coating, but the parts van hadn't been on fire. Thanks

Sounds like clear coat.
Was the donor ever painted?
Perhaps the window was not masked off.

[debbiej]

Ok, I think that is what it looks like, thank you! Razor blade my only option?

Try wiping it with lacquer thinner first--or spraying a little oven cleaner on it.
If it's clear paint it'll come off with the E-Z off or lacquer thinner.

Hint;
Use some 0000 steel wool with the lacquer thinner and it'll have whatever is stuck on the outside of the glass off in a jiffy.

Thank you, I'll try those!

Yes, after the solvents, try a razor blade.
Becareful not to use a blade on the inside of the glass or you will scrap off the heating elementts for the rear defrost.

Razor blade is too slow.
The 0000 steel wool will not only remove whatever--it'll polish the glass.

Try using it to apply rain-x on your windshield--then buff it off.
The water will run off in buckets, sheets.

Good one TK, I will try that with the RainX.

I accidentally got some red urethane overspray onto the glass of a tracked excavator while painting the front end of a Mack.

The operator was on the phone the next day really screaming.

Grabbed the 5 gallon can of lacquer thinner, and some 0000 wool, and went out to the job where grumpy was.

10 minutes max--the paint was all gone--hasta lavista baby.

I use the steel wool to clean the outside windows of the house.
For some reason it makes whatever your using to clean them with a bunch faster & cleaner.

And using it with the rain-x really make the rain water roll off your Vehicles glass--

It's a Miracle!!

Amen.

The lacquer thinner and 0000 steel wool worked. There are still some odd spots, almost like something has gotten into the glass, but really it is looking much better, almost completely clean and clear. Thanks!
