How do you guys clean air filters?
I have tried soaking in Simple Green but it looks like that does not get all the oil out.
I have been cleaning with gas and it removes the oil well but over time my filters get orange spots all over. Is this rust or dirt that is not getting washed out all the way?
Thanks
