Cleaning inside radiator

How can you make sure the inside of the radiator is clean? I just shot water through mine and it comes out nice n perdy. Is there a chemical solution I should soak it in?

This is just a guess but, CLR???? Can anyone confirm/refute that???
DISREGARD: I just read somewhere else that CLR can eat through copper. Unless someone else can prove that isn't true I suggest you don't try it!!!

That's what I was thinking. This is all aluminum from what I can tell though.

clr eats copper like drano and liquid plumber eat pipes.... but people still put it in pipes.

as long as you flush it out in a reasonable amount of time... (30 hrs?), it'll be jsut fine.

hcl "eats" copper, but that's why i use it.... i use toilet bowl cleaner with 10% HCL, and yes, it eats copper, but that's why i use it!!!! it eats away the surface layers, which may include corroded, nasty crap and other undesireable stuff, and acts as a "polish", or much as sandpaper does.

because a cleaner dissolves copper, doesn't make it bad, it just makes it useful....


i wish people wouldn't jump to conclusions without thinking about it first....

the phosphoric acid (sp?) in coca-cola also make coke an excellent copper cleaner.

white vinegar and seasalt have been use by cooks for many, many, many years to clean their copper pots.... (vinegar = weak acetic acid, i think)

ammonia, also......

most acids will do the trick, just remember, the more concentrated the acid, the less time you have to soak it.

if you get some 12 molar sulfuric acid, i wouldn't let it sit in yer copper for more than 2 mins, TOPS>..... LOL..... if you got it, send me some of that 12 molar h2so4, i could use some.....

It does have a copper core now that I have it apart. Thanks for the information guys. This is a sweet 12.5 X 12.5 inch radiator with a little 1/4 hp fan and shroud. I'm gonna have to mount it outside of the computer, but i should get room temps.
