    Purple Power was one of the first mentioned in the EGR cooler cleaning thread because it won some comparison test, and it really does work well. I got mine from pretty clogged to spotless/like-new in over the course of about a day. First you need to push all the way through each passageway with a stiff wire (hand rotating the wire as necessary) under running water at the sink. Then do soaks in Purple Power with the cooler plugged up. I actually started with a Purple Power soak before trying the wire, but would go straight to the wire poking first if I were to do it again.

    I saw a comparison (of diesel EGR cleaner?) where Purple Power was highly rated. Unfortunately it's hard to get locally. So first I went with brake cleaner, but the results were so-so.

    @mjoo suggested OxyClean; I had an enormous box of it on hand, so I gave it a try, with very good results.

    I suspect PP is similar formulation, a moderately caustic cleaner. Maybe some other trace ingredients, who knows.

    I prefer Oxy in powder format, buying a big bottle of liquid format cleaner is likely less economical?

    I got a gallon of Purple Power for around $6 at the local Walmart, so that was pretty cheap. I ended up using very little of it, so I'll find some other uses for the remaining.

    It doesn't hurt to use brake cleaner or soak with Oxi Clean to soften the crud before pushing a wire through the ports. I filed a point on the wire tip to aid easier push through. Done the ports twice, may do a third time. Been sick for the last few weeks so progress has been slow. :(
