I know that.. partly a possible cultural gap, partly my never bothering to cover the basics, though it appears i once again should have. Surprise.
Where liquid -could- harm your cooler, could
, it will not; because it is plated and soldered. Shall we frame it thus and finally call it a day?
Anyway, i've never had rust, discoloration or any other issue with cleaning air coolers the way i have been. As stated in fact, they still look brand new; despite their age and in some cases (chipset coolers, particularly my HR-55), heavy usage in adverse conditions, as i used to smoke in the office. Even so.
But you guys are obviously free to discount it.
Here, i'll help. Coolers get grey and rusty in a few years, nothing we can do about it. To quote another poster here, it's only natural.
