Apparently I slipped into an alternate reality while sleeping. Old minor car parts and rusted/chopped up hulks now sell for thousands of dollars, electric cars are "Cool", and I'm some sort of contrarian fossil.

OK, fine, my turn to cash in!

The Carello 03.490.800 headlamps I bought a few decades ago for my XKE are now worth stupid amounts of money. So much so that I can no longer even consider using them for my Alfa Spider as I had intended.

Apparently they are OE for certain models of Ferrari, Maserati, etc.

To get full value I need to find a way to clean them inside, they sat around without bulbs in place for a few years. They are not really bad, not pitted, just a little dull and dirty so not up to full reflectivity.

I know there were headlamp restoration companies, if any have survived the China Virus, but they are expensive enough that if I cannot clean these myself I may as well just sell them for less and let the buyer have them restored.

So looking for safe suggestions, cannot risk making them worse!

I have had good results with isopropyl alcohol, just sloshing it around and pouring it out. I had some that hazed the lenses from I don't know what, the bulbs were still in. Also used some cotton wadding on a bent plastic stick for a real dirty spot on the reflector of a Cibie  H4., again with isopropyl.

In reply to TurnerX19 :

I've also used isopropyl alcohol to remove the fog from the inside of Porsche headlights. Try to find the 90% rather than the 70%. It seems to do a better job.

If they're glass, you can probably pop them in a warm oven, around 140 degrees to soften the glue and pop the lens off of the reflector, then glue it back together when you're done.

That's how the Ducatisti repair the JOD Duplo headlamps.

Just to prove my point about scrap going for silly money, Um, yah, it's a Ferrari!

This is how I cleaned the Cibies I have on my Oldsmobile after it sat for a few years.  Cleaned them right up like new.

70% improved them a little. Could not find 90%. Might get some when I visit the big city in a couple of days.

Probably putting them on feeBay as soon as they are as good as I may get them.
