hey everyone, As the topic says, is there a proper way or even a way to clean the core of an FMIC? Specific Liquids? Specific Tools? Thanks a lot. -Sean Schreiter ---

Do you mean interior, or exterior? If it’s interior, buy a 4L jug of denatured alchohol. Cap off one end of IC, pour and shake! 😃 ---

I use simple green and a preassure washer on my dads car to clean the IC, you have to make sure that when you use the pressure washer that you have the water set on a large fan not on a point, and that you hold it a good 3-4 feet back from the IC so that you dont bend the fins. ---

I’d try a solution of CLR & water. Cap off one end, pour the solution in and let it stand for 10-20 minutes. Empty & rinse thoroughly with water. ---

Go to home depot and find yourself some BORIC ACID, its crazy corrosive, it’s used to clean alluminum and other metals before chroming, plug your intercooler off , fill it half way, let it sit, turn it over the way, let the half sit, then dump into a sealed container and dispose of. WARNING: this will burn your skin, stink ur house up and eat any paints, finishes, grease anything, it also destroys asphalt, but concrete holds up. ---

break parts cleaner is the best i find you can use this and for exterior cleaning use the aluminum wheel cleaner stuff
