Hi, got me a new watercooling set.

Amongst other things Fesser tripple rad and D-tek fusion v2.

Now, in the manual to the Fusion it is stated that you should not clean your block with any strong detergent (alcohol, acid, whatever) since it is coated with an oxidize protection.

So should I just clean it with distilled water (demineralized)?
What about the Fesser rad that is 100% copper, should I even clean it with vinegar at all, or just flush it with D-water?

Thanks.
