I apologize if this is a repeat question but I can't seem to find the
previous post.
What were the solutions to removing yellowing from the plastic cases? I
bought a printer that looks terrible. Not sure what caused it so any
suggestions helpful at this point.
thanks,
Greg

Greg,
I have found that a biodegradable solvent called "Citra-Solv" works well
for most high-quality plastic cases. It's pretty potent stuff used full
strength, so the trick is to put it on a cloth and rub down the case and
then to clean it off with water. You probably want to use rubber
gloves. If the case is really plastic, and not painted, it takes off
the outer film. (If you leave it on full strength, it will dissolve the
plastic!) You want to do just enough and not too much. Most cases come
out looking new.

It's not (IMHO) always possible.
If the yellowing is due to the previous owner smoking, then often a good
clean-up (Electrolube foam cleaner is good here) will get it looking like
new. Alas, the plastic used by a lot of manufacturers (DEC, for one)
actually yellows with age and sunlight, and I've never managed to reverse
it. Maybe lightly sanding the surface would help, but it would remove any
labels and surface texture, and would be a lot of work.
thanks,
Greg

I've always just used those blue brillo pad thingys. They generally do
well at taking off a bunch of hard to remove stuff (tape spooge, stains,
etc.) Sometimes when I'm REALLY bored I take the keyboard apart (keycaps,
etc.) and scrub them up too. Real satisfying to see a 12 year old machine
look like new...

Regarding "tape spooge" (what a great moniker, if not gross) this is the
bane of my existence. I hate that shit. I went out and got some stuff
called Goof Off from Home Depot which was supposed to do away with that
stuff but it didn't work very well. I didn't try it on anything metal
yet, but most of my problems are with people putting velcro with the
sticky backs on plastic cases. I tried cleaning some plastic with tape
spooge on it and it just melted the damn thing. Anyone have any ideas?

I have a great idea... I have been working on refurbishing several Tandy
200 laptops for a friend, and one of the laptops had about a dozen stickers
on it (including bumper stickers -- the worst! ;-( ) ... a few stickers
came off, but most left "sticker tracks".
I went down to my local hardware, and bought a quart of straight Naphtha.
=$2.79 locally= (It's a component of lighter fluid...) It is *highly* -- I
say again -- *highly* flammable. So flammable, *thinking* about having a
cigarette will touch this stuff off.
But: It doesn't melt plastic (well, maybe if you soaked it overnight or
somesuch foolish thing) and neutralizes tape spooge (one of my favorite
"words," BTW) in the blink of an eye!
The fumes are kinda harmful, and it evaporates so quickly it will suck the
moisture from your hands (those with sensitive skin, wear rubber gloves) so
don't leave the cap off for a weekend in the basement... you'll be greeted
with a highly explosive basement and no mo naphtha.
This is one of the few solvents that easily dissolves wax (candle,
paraffin, and others) and I learned about it while learning to make
candles. It works good for clear wax as well, but it won't get a stain from
the dye out, that I've ever seen. So it may work well on removing grease
pencil wax, but if the dye in the grease pencil has stained the plastic,
try another of the fine suggestions here.
Sam,
Regarding your post about L.O.C. (which stands for Liquid Organic Cleaner,
BTW, and was Amway's first product over 35 years ago) do you dilute it
first (as per instructions?)
L.O.C. mixed 1:1 (water:LOC) is also good at getting crayon off of walls
(as always, hope there's decent quality paint when kids are around) and
mixed 2:1 works great for getting the green gunk out of the grooves of your
golf clubs!
Hope this helps,
Roger "Merch" Merchberger

Sounds good. I'll have to go out and get me some. And maybe I'll use it
to clean my computers with too. :)

Like I said about this citrus orange cleaner, it does the trick. Naphta
sounds fun though, and it would be cool to say also, if it wasn't a
synonym for a trade agreement acronym.

I used it from a spray bottle which has a dial where you can adjust the
dilution anywhere from pure water to pure LOC. I normally have it on 3
or 4, which is 1:1 (water/LOC) and like .5:1 respectively. Too much LOC
just makes it too soapy. It seems you definitely need the water for a
good cleaning solution, although soaking in LOC sometimes does wonders.

Ok, I'm about 10 days behind, but for cleaning plastic, especially cigarette
smoke (computer is yellow, vaguely sticky) soft scrub works well. The citrus
paint thinner cleaner being discussed is called Goo Gone. It works well for
sticky messes (IE you got ahold of my old commodore monitor and tried to
peel the bumper stickers off... oops).
