Since were talking cleaners... I was working on my intake manifold. and got shavings all in the runners and plennum. I tried brake cleaner but the shavings were stuck in the black sut and sh!t in the manifold. So i grabbed a spray can of paint stripper from Canadian Tire. Bought it to remove the coating from my valve cover. Worked perfctly.. Sprayed it into the intake manifold and used the rest of the can. Cleaned it up pretty good. Ate right thru the gunk!
