    Can I soak it in something? I do have an ultrasonic cleaner but not too sure about that. I've been told not to use Purple Power. I could just soak it in mineral spirits for a week, then pressure wash it out. Looking for the easy way out, but I'd like to get it going today. This is a spare I bought on EBAY but the seller just cut it off a car, so it needs cleaning.

    Also, the hoses they cut off were pretty difficult to get off. I'm thinking I should just replace all the hoses that run to it.

    Trying to line it all up where I've got pristine, cleaned parts before I start the job. EGR valve and intake manifold are new. Ready to do the job the weekend after this one. I'd rather spend a little more and be completely ready. If I don't finish in a weekend, my wife will complain all week.

    The quickest way is oven cleaner with a pressure washer.
    But if you plan on soaking it since it's a spare one, almost anything will work.

    Some use purple power, mineral spirits, gas, diesel, gunk, carb cleaner brake cleaner.....
    Some use some oxi stuff...... you'll have to change them out every few hours or so and unsure
    on how many times. But if you're not in a hurry....you could change it whenever you wanted too.

    Will purple power damage it? I've got an ultrasonic parts cleaner I could use with that. Does amazing on many things, but I've heard it can damage car parts. Heck, rather than buying mineral spirits, I could soak it in gas for a week.

    Yea, I forgot to say something about that! I guess it couldn't hurt. Give it a try.
    I don't know what the othe people have used as the cleaner.
