Hi people.
This may sound a little dumb, but I have my doubts about how to clean the exteriors of a venerable machine I got recently.
There are a lot of tips on how to clean the internals, but I haven't found any thread about cleaning the outside. If it had a plastic casing, I wouldn't have any doubts - probably warm water with a light soap. But as it is a venerable metal machine (it will weight a ton or so), I have the following doubts:
- I don't want to cause any corrossion, so water is totally forbidden.
- Alcohol based products (or pure alcohol) will probably damage the painting.
- Any other solvant, petrol or synthetic products will probably have the same negative effects on the paint/coating layer.
- I can think of some furniture-cleaning sprays but they tend to leavy things shiny and greasy and I don't think if it's the best approach, either.
As a side note, it's not only dust and particles that could be removed applying compressed air, but this machine has a thick layer of dirt stuck on it ![[Razz]](tongue.gif)
What kind of products or process do you use to clean the outside of your metal projectors??

Thanks a lot for your tips! I discarded the vinegar because it's acidic and certainly can corrode metal if applied for a long time, and probably could damage the paint coat, too.
About WD40: I got the first can in my life about a couple of months or so. Still it was unopened. Although I "know" it from the net, in this land it's not much known, for sure, and we don't have that notion of it being an "all-purpose" "miracle product" for almost any usage, but more of a an all-purpose lubricant oil like "3 in 1" or so. I tried it on my machine but only helped for the more external layer of dust - it has such a layer of grease and stuck dirt that it couldn't remove it.
Finally I couldn't resist aplying some dish soap dilluted in warm wather gently with a cloth, drying it very quickly. I started on some plastic pieces, like in a set of 4 switches for operating, and immediately the efects were obvious. I was more reluctant of applying it on the metal casing itself, so did it in selected areas and was very quick in order to not apply moisture for a very long time, so in the end it's not totally clean, but at least I can put it on the shelf for display ![[Big Grin]](biggrin.gif)
The truth is the only thing that could properly clean it was wather with soap, so I think we still have yet to find the best product for use on metal parts prone to oxidize...

Hi Will,
I got it from a flea market. It didn't have any box; it was on the outside. The mains cable is missing, too, and it's not standard. A pity, because the socket is bigger than usual and no cable I have at home will fit in there. So I haven't been able to turn it on yet.
It's a Hanimex Loadmatic dual P300. Strangely, I haven't found any info about it on the net. I bet the seller got it from the dumpster or so. That would explain the amount of dirt on its surface, appart from the fact that it's very old - I would say from the early 70s. But appart from that, it seems to be in great condition, and it looks like a venerable machine I like aesthetically. The casing is 100% metal, and the few identifiable plastic pieces aren't weared of cracked. It's a dual, silent projector, and it weights a ton - almost the same as an Eumig s810D or even a bit more, despite being a 10-20% smaller.
Haven't dismantled it totally yet, appart from the piece covering the bulb, which is a 50 W one with the common "astronaut" shape.
I bet it doesn't have a rubber piece on it and that works flawlessly; looks unbreakable.
