Catastrophe - help required.

[Trevor Wilson]

I managed to get heat transfer compound on my favourite T-shirt a few
weeks back. Naturally, the compound is white and my T-shirt is black.
Standard washing powder doesn't remove it. Any ideas?

Dunno if you can get it down under, but I swear by a veterinary shampoo
called Orvus WA Paste. Gets spaghetti sauce out of white shirts, you
name it. You rub it in vigorously from both sides of the fabric, toss
it in the wash, and it comes out clean as a whistle.

Waterless hand cleaner. It will take out lipids, THEN the white pigment
(maybe zinc oxide?) should loosen and fall away. If you have an ultrasonic
cleaner, that's also good for final cleanup (but remoe the greasy stuff
first).

If it is zinc oxide pigment, dilute lye will dissolve it.

Don't rub, though.

I dunno if you can find chlorinated brake cleaner in your part of the
world but if you can it will probably work. Or chlorinated electric
contact cleaner. Both use perchlorethylene, which also used to be used
as a dry cleaning solvent. The solvents will be advertised as
non-flammable and will be in spray cans.

I'd try something cheaper, safer & on hand first, paraffin/kerosene.

Removing Thermal Compound - The BEST Way?
<https://www.youtube.com/watch?v=VOd1oN1wPSk> (11:06)
Conclusion: 91% isopropyl alcohol (or maybe acetone) for the thick
thermal goo, and just about anything (except orange juice) for the
thin thermal goo. I suggest that you test any solvent on an obscure
part of the t-shirt to make sure the black color dye isn't affected.

However, that just removes the greasy carrier leaving the zinc oxide
granules behind imbedded in the weave of the cotton t-shirt.
Additional solvent attack isn't going to do much to the remaining
granules as zinc oxide is not soluble in organic hydrocarbon solvents.
However, it is dissolved by most acids:
<https://en.wikipedia.org/wiki/Zinc_oxide>
It is nearly insoluble in water, but it will dissolve
in most acids, such as hydrochloric acid.
and some bases:
Solid zinc oxide will also dissolve in alkalis to give
soluble zincates.
The black dye will probably be attacked by HCl which will also burn a
hole in your t-shirt. To avoid this, I suggest using a mild acid,
such as white vinegar instead. For a mild base, I suggest any of the
common household cleaners (409, Fantastic, CLR, etc).

If you've removed the greasy carrier, but the zinc oxide remains, I
would try mechanical extraction using water and compressed air. The
air flow will expand the cotton fibers and hopefully release the zinc
oxide granules.

Disclaimer: Since I don't wear black t-shirts and am not in the habit
of cleaning heat sinks with a black t-shirt, I have not had the
opportunity to test the effects of the aforementioned recommendations.

I've always liked either Gunk or mechanic's hand cleaner (the kind that
rinses off with water, not the kind that you just wipe off) for greasy
spots. Work a blob of it around with the edge of a teaspoon against
your hand for a while and then wash. If the spot isn't gone DO NOT PUT
THE GARMENT THROUGH THE DRYER. Let it air-dry and try again.

That ain't nothin'. One of my folk is a bounty hunter, we hook up when we can. He is enjoying every minute of insanity of course.

Calls me up last week after we hoked and I got in his truck. I was at the bench and had to grab something with my right hand and my left hand was busy. I hit a bunch of that birdshit and I needed it off now. I wiped it on my pantleg.

No more of that.
