To avoid the risk of damaging the reflector, or in case you have a unit that does not separate, try dental cleaner pills, the ones that start to bubble and fizzle when grandpa puts them together with his teeth in a glass of water before he goes to sleep. Don't know how they are branded elsewhere, here in Germany well known as 'Corega Tabs'.

We applied this trick successful many times in the past, when the TUEV disliked the blinded (not rusted) headlight reflectors on our 300,- wrecks, which we usually drove back then. I did this also on my sealed Japanese 8' Laverda headlight, and it came out like new.

Just drop 3 or 4 pills through the bulb opening, so they come to sit on the inside of the lens, then fill to the top with pretty warm water, then let the bubbles do their work and have it sitting for a few hours. After emptying out the broth, flush generously with tap water, finally flush with a good load of De-ionized water. Then dry out the headlight by using a hair dryer until its bone dry again.

I knew a girl that used a similar product, but for upset stomach .............. she never used a glass of water though, rather, inserted the pills before sex.
Curious, but oddly affective ....... so I'm told ;D

Hmmmmm ...... denture cleaner tablets here ..... I bet that if you used them as you say but rinsed with methanol (methylated spirits) that would remove all the water. Then a session with the hair dryer to finish off.
I have a Japanese headlamp I shall try that on first ...... see if I can start a fire!

Methanol is not methylated spirits.
That is around 95% Ethanol, then around 5% Methanol, with a trace of taste inhibitor like Bittrex or Pyridine to stop folk drinking it.

I agree ..... but if you try to find methylated spirits here in Canada you will get strange looks asking in stores. If you try to search the net to see where you can purchase it you will get nowhere. Even if you search for the proper North American name .... denatured alcohol ..... you will get nowhere.
However ..... if you ask for methanol at the local auto parts store .... they will show you methyl alcohol ...... or branded methyl alcohol .... but when you read the label you will find it is methylated spirits and the methyl alcohol label is just the trade name.

I know this from spending an hour on the computer and driving to 5 different stores today. So much fun I had ..... not.

Sounds like the "Swedish White Whiskey" I was given on my first visit there....

Jim, I have used water for rinsing, as I was not sure about ethanol probably messing up the seal between lens and reflector. Anyway, I'd recommend to make a test with that methyl, or whatever the stuff is named at your place, just to make sure that it evaporates off a clean surface w/o leaving any stains.

Denatured alcohol is what we used in hospital for cleaning mirrors, windows and stainless surfaces. I presume it doesn't leave too many traces.

It's not used anymore because some patients would steal it for their personnal use.

I thought hospitals use isopropyl alcohol for that sort of thing, as in Isowipes.

Used, as in past tense.
Now they would.
