cleaning copper

[pete]

looking for a good cleaner to clean inside my alphacool cpu and n-bridge blocks as they are tarnished inside. been using fluid xp for a year now,anybody have same prob or is this normal build-up

[llwyd]

take the block apart and leave the copper base covered in some tomato sauce for a few hours

As soon as you remove it though you need to wash it and be quick about it. Otherwise itll retarnish quickly.

I left my block overnight in vinegar and it turned the block green. Looked awful

i think that happens in warmth, the acetic acid evaporates first, leaving the ions it has dissolved reform onto the metal, not too sure on that though :/

I dont think ur supposed to leave it for a long time, I think you use it with a brush than rinse.

Tried it. Forget it. Use white vinegar, make sure the copper is submerged. MUCH better. Easier to clean too, just rinse.
