Default How to make your intercooler look brand new DIY

my tmic is real dirty, is there a cleaner that will break up the dust dirt and grime on the intercooler and make it look newer? best way of cleaning it?

Tried:

1.Engine degreaser+detailer
2.P21s TAW
3.Simple green

4.duragloss aluminum cleaner (success)

I used maybe 1/2-2/3 of the bottle, i saw noticable difference after the second time i sprayed it on. I maybe did it 5 more times just to be sure i got in every row. Let it set for 2 minutes and hosed it off. last pic doesnt do it any justice, looks 10x cleaner and shiner, cant wait for a sunny day to make a good picture.

Before:






After:






Mounted

A tire scrub brush and a power washer will do wonders for it. If regular soap doesn't work, try brake cleaner.

I keep my engine bay spotless, doesn't much to maintain and keep it that way. Spray the intercooler and the rest of the engine bay with Simple Green and let it it for about 10-15 minutes and spray it off.

Your welcome

try some P21s I think its called?? I use the P100s motorcycle cleaner which is the exact same thing (bought it from a harley store) I let that sit for maybe 15 mins then took a boars hair and then a more rigid brush too it, worked great! Then I pressure washed it to finish it off. Be careful though you can bend fins if you get to close or scrub to violently.

if you read the back of the degreaser it says to wipe it off any painted surface+ wax it after because it will eat the finish.

How about trying a cleaner specific to cleaning aluminum and oxidation on aluminum, instead of trying products that are designed for completely other purposes?

You need to acid wash it.

http://www.google.com/products?q=alu...num=1&ct=title

Diluted hydrochloric acid will do it as well.

And please take it off of the car before you do so, and wear protective gloves/respirator/etc.

Depends on if you soak it in the acid, and for how long...It's perfectly acceptable to brush it on and control where it goes on the IC...

You can just dip a toothbrush in the diluted solution and lightly scrub away and the oxidation should just basically vanish.

But yes, do this with the IC off of the car please.

A guy I know uses cleaner for the fins on air conditioning units. His STI logo is still there and his intercooler is nice and clean. I keep my engine bay clean so never needed to try this.
