Watercooling best way to clean a waterblock???.

hello my fello computing friends i need help on this one what is the best way to clean a crusty waterblock ???

 

Open up and use a toothbrush

 

i got told by a friend to leave it for 4hours in a shallow bowl of lemon juice and brush it with toothbrush and rinse with distilled water then dry with paper towel is this true i wonted to see what the people here would advise as there are a lot of watercooling people about here on bit-tech...

 

I've heard tomato ketchup is good?

 

Basically anything with acid in it works, I find vinegar works well. Rinse of with tap water and your good to go.

 

Yep white vinegar and water

 

If you know any one who works in a pub ask if you can have some pipe cleaner.

 

And don't get it into any cuts

Personally, tomato sauce... messy but works real well.
