Use Autosol,followed by a TIM cleaner myself.
The best way to clean the base of a block is with 1200 wet and dry on a piece of glass using water and fairy liquid.
Using Brasso on a cloth with your finger would not really be advisable.
Rubbing around with an abrasive just with your finger is going to wear the surface un-evenly.
Best to keep the base as flat as possible.
tomato ketchup is good![]()
Maybe if you did it a few hundred times
Maybe if you did it a few hundred times, you don't have to apply much pressure with brasso and if you use a good thermal compound my CPU block is about 4 year's old. Just serviced my custom loop after 2 years new tubing, coolant and cleaned the block face with Akasa AK-TC TIM Clean CPU & Heatsink Cleaner +brasso.
.So is the general consensus a yes or a no for brasso? It looks like it's done a fabulous job to me.
I think the best answer for anybody who finds this thread while searching about cleaning copper is, don't bother its more trouble than its worth lol.
Is it better to buy a new waterblock whenever the old one is all oxidised and gunked up then?![]()
(I know the threads been dormant for almost two weeks but I hadn't seen this reply).
My point was that as oxidization has 0 effect on temperatures, messing around with cleaning stuffs on the contact plate is just wasted effort/time, the only things that will ever see how shiny it is are you and the IHS, it may not be very often that something goes awry but its still risk for no reward.
Why are you polishing the base of the block? I can only assume its to obtain better performance.
If you want the best performance I'm just pointing out that its best kept flat.
