dirty halogens

I have a pair of halogen bulbs that have been knocking about for a while and despite my best intentions have thumb prints (and worse) on them. I was planning on giving them a good clean with meths before fitting. Does anyone have any better suggestions (for the bulbs not the meths)?

I believe this is what you're supposed to do with them when they get finger print and dirt on them.

I normally use thinners to clean them

Well that explains why it says not to handle the actual bulbs.

If you do not clean the halogen bulb before fitting, the oil from your fingerprint will make the bulb explode! We used to do this at the youth club where there were halogen bulbs fitted to the outside lights. 40 years ago, this seemed to be good fun.

Thet were 500 watt floodlights.

The earliest type of halogen light bulb was patented in 1959, but I don't know when they came into widespread use.

Why do Americans always seem to have such a downer on Lucas electrics? ISTR there was even a movie where the car-mechanic protagonist made jokes about how unreliable Lucas ignition is...

Same reason as anyone else. They were **** (Insert your own four letter word). The semiconductors in the alternators were unreliable with rectifier packs giving up the ghost all too often. The brush wear on rotating machines meant they gave up way too soon. The mechanical bits of the distributors wore out and gave poor timing. When they started doing automatic jokes (meant to be chokes) the control units used to fail at an alarming rate. Need I go on?
