Dark "Stains" On My Rasa - Page 2

post #11 of 19
That's what I meant, edited above.

It's on the outside of your block so unless you scrub so hard that you deform the CPU plate then I doubt there's any harm in trying. I've heard toothpaste used on the internals of waterblocks to clean out gunk. Could try that. Though to be honest if it is oxidisation I wouldn't know what to recommend

edit: looks like some good suggestions were posted while i was typing!

I have a light layer of ketchup on the affected areas, how long should I let it soak?

Also, I remembered the stains a lot darker than they actually are, they are actually pretty light.

It's your tim. What are you using? However is it on the slug portion or not, if not it's just normal oxidization.

Ketchup worked great! All stains gone

+rep to all in a few minutes, it's hard doing it on my little netbook.

Wait till you take a look on the inside and see the darkness.

I actually clean the inside out every two months, next time I clean it I'm gonna do the ketchup treatment.

Uncoated copper oxidizes...



It's nothing to get worked up about as it doesn't have an appreciable impact on performance... you're fighting a losing battle. That said, if a block gets really, really bad, then my OCD will kick in and I'll end up hosing the thing off with some Weiman instant tarnish remover (the not-quite-nuclear option ). Acetic acid also works (that's what's in vinegar and ketchup).

While cleaning the block, I noticed that my TIM hadn't spread over the whole CPU (used rice method), so I applied more than I usually do and now my temps are 5c better

Just don't let the ketchup stay on the copper too long. It will eat into the copper if you leave it on overnight.
