Whats the best method/spray for cleaning (computer) plastic?
Its VERY important that only dirt gets off and that original plastic
is left intact.

I've always used "409" ("Formula 409") to remove grime from plastic.
It's a household cleaning product from Clorox and -- uncertain what
your domicile is -- may only be found under that name in the U.S.
and/or Canada.

And, I always spray (generously) _on the cleaning rag_ and then wipe
on the piece to be cleaned. Letting the "problem areas" sit a bit
before wiping it off helps cut through the worst of it.
Really bad grime can take multiiple applications (and, multiple rags!)

I used to repair Olde Fashioned typewriters, adding machines, etc.
Some of those keyboards had not be cleaned in *many* decades.
"409" was the cleaner I finally settled on.

Someone once advised me to buy Simple Green to clean off some circuit boards
which had been badly smoke damaged. It didn't work too well; but when I was
cleaning a particularly nasty white tile floor with 409...and getting
nowhere, I remembered that bottle of S.G. in the shop.

I sprayed an area with the 409, let it sit and rubbed, and did the same with
the Simple Green. The difference was pretty amazing. The S.G. won hands
down.

I became a convert...but I only use it for stubborn jobs--very heavy soil or
tough stains. You must follow the directions, and never use it on
glass...even well diluted, it will leave a film (although ammonia will
remove that).
