removing goop from 70's phase 90

[nag hammadi]

hey guys.  i friend gave me an old original script phase 90.  his dad found it at an auction for $5...

i opened it up, and MAN what a mess.

that foam padding stuff has disintegrated and is all over the board.

the parts themselves don't look TOO bad, and i will probably be able to salvage most of it, but the foam is all over the place.

and it is stuck to the traces on the bottom of the board.

what is the best way to clean this crap off?

i am picturing a toothbrush and ...?

a quick look at ebay showed these going for almost $300 with the box (which i have), so i am thinking it will be worth jumping through hoops for.

i used Ronsonol lighter fluid to clean mine... it dissolved the foam residue right away...

[jonathan perez]

lighter fluid? wow...i gotta try that later.

otherwise, i just use goo-gone...

or goof-off...

Lighter fluid and goo-gone should be good for removing gummy residue. IIRC, both are essentially naptha. In addition to a toothbrush with good stiff bristles, a set of dental picks could also come in handy.

Water. You can wash off circuit boards as long as there aren't any pots or tuning caps (if you are working with radios). Be sure to dry everything off good too.

Sidenote: I have to use either airplane model dope thinner (which uses MEK) or Bix Stripper (which I'm pretty sure has some MEK as well) to get the PnP Blue off of my freshly etched boards. Anybody else have to use such strong chemicals? That's the worst part of a build for me, not the preparation for the etching but the act itself (I use Ferric Chloride, works fast), cleaning up the board and drilling the holes.

I use LPS Noflash contact cleaner to remove PnP from my boards. I bet it would work on the foam goo too.

I use acetone, I've tried lacquer thinner once. Both are pretty strong solvents that would melt certain plastics. I'm not sure how strong those chems are compared to MEK.

Goo Gone is almost pure citrus oil, and will probably leave its own goo behind. Acetone(nail polish remover), lighter fluid, or rubbing alcohol(preferable) will do it. Of course, dry brush as much of it out as you can first.

Aahh... that is what they would like you to think. Have you used Goo-Gone? It does contain citrus oil, d-limonene, but not as much as you might imagine. Goo-Gone is mostly a petroleum based solvent with a smaller percentage of d-limonene mixed in. Even if it was pure, D-limonene is a terpene, as in turpentine. It does not leave goo behind. It is strong enough to remove gum/glue but gentle enough not to affect most guitar finishes (I have used it to remove stickers from a guitar I was restoring).

On a related note: I have used Goo-Gone to clean fretboards but is dries up the surface too much for my liking. So now I use Orange Oil (d-limonene plus mineral oil) from Rockler.

[Meanderthal]

Have you used Goo-Gone?

No, I'm suggesting things I've never had any experience with...

As a matter of fact, I've used quarts of Goo Gone. Whatever the chemical composition(and they must have one HELL of an orange peel perfume to mask all the petroleum solvent), it always leaves behind an oily residue. I cannot imagine the residue going away on its own. I can also imaging dust and such sticking in it over time, causing yet more goo. If ya wanna get a sticker off your car, or crayon off your walls, that's the stuff.

+1 on the Goof Off suggestion.

Harsh chemicals though! Use proper ventilation etc.
