Upgraded to Bosch H4 glass headlights a while ago. Noticed they have a whitish haze inside them. Similar to what happens to. Modern plastic headlights.
Happen to anyone else ? Any tips on how get rid of the haze ?
Thanks !

Don't rinse them out, because you will affect the coating on the reflector. Learned that years ago!

Interesting. Someone else told me to rinse them with Windex, dish soap and water.
What happened with yours ? What did you rinse them with ?

Soapy water. The coating on the reflector is affected by moisture. The whitish haze will be from bulbs going bad. Buy the best bulbs you can get. You might try cleaning the lens with a piece of micro fiber cloth tightly taped to a small stick, dry. It will require patience.

Had a set of Cibies rust back in the 70s, have a set of Hellas now since 2003, still perfect with 2003 bulbs. Must be some of this new crap being made. Got warranty? Ask Bosch too?

That's what I did on mine, Easier to do on the low beams because you can get a soft dry cloth on the end of a rounded marker top and move it around on the surfaces.
There's not really much of an opening in the high beams which makes it more challenging to clean them, but you can improve them.
