i have sanded and polished the endtanks but how do i polish the tubes that run side to side. i have the Greddy FMIC and i tool it to have the inside cleaned out while i have everything out and the place did some kind of acid wash that they use on big diesel truck intercoolers and now the aluminum rows are dull. any special tool to do this? the endtanks were easy but i clueless on how to polish the horizontal rows

 

just use some scotch brite and your finger, it may take forever but itll work.

 

dont waste your time. theyll just get dirty and banged up from rocks/debris and normal everyday conditions.

 

what about for car shows etc... I'm curious to.

 

Thats why so many show cars are trailer queens. Either that or you have to have the houseboy wipe down the entire car every time you take it out.

 

It's unavoidable it you actually drive it.

 

sonic clean it

 

try some oxyclean and the use a shamwow to dry it up

 

Mothers Aluminum Polish and one of these:



As for the fins, Acetone and a toothbrush = Sparkly Clean!!!

 

The OP asked how to clean his intercooler fins, not how to envelop the universe in a Billy Mays vs. Vince product combination-of-mayhem.

+1 for Mother's alum polish and lots of time...
