Ok, I've only cleaned my intercooler once with paint thinner and I did it in my bathroom. The fumes basically stayed in my house for a couple of days and everybody in the house got high off of it!!!
Well I don't plan on doing that again but I need to clean my intercooler because I can see a lot of oil coming out from it when I was fixing my UICP. I know you can also use gasoline but that's worst than paint thinner. Has anybody use a different type of cleaning solution that does the same job as paint thinner and gasoline????
