hey i just recently purchased a large npr intercooler and it aint exacly clean so to speak. whats a good way to clean up all the fins/ros and **** that i cant rub and or grind down?

 

just like old dirt and what not from being used.

 

Try soaking it in like simple green in a bathtub or something. Done it before with my friends turbo II before he got a fmic

 

Get some steel wool. (sp?) I found this works awesome on my stock intercooler. Just be careful of the letters or any print, the wool will rub it off.

 

For cleaning fins, I use Eagle One Aluminum Rim cleaner (I use it on my rad, that is - NA.)

Spray the fins with LOTS of the rim cleaner, then let it sit for half an hour (out of direct sunlight and somewhere outdoors - the fumes will be nasty.) Then rinse it with a garden hose. Repeat as desired.

 

IF you use steel wool, use the finer stuff like 0-0-0 or even 0-0-0-0 and the finish will be better.
