Clean blocks before install?

[SVTtruck02]

I recently bought a used cpu and vga water block. The cpu block looks fine, slight swirls ( normal from what I've seen). But, the vga has finger prints and looks pretty dirty.

My ? is, what do I need to do before I install them? Just clean w/ some nail polish remover or....?

Fingerprints are just a cosmetic problem, they won't alter performance. If you really need them gone, Brasso or another brass/copper polish will remove them. Just be sure to clean off the all the polish.

Nail polish remover contains more than just acetone, and will leave a residue. 90% isopropyl alcohol will work for cleaning off finger oil and left over polish.
