I started using Steelgard CLP in mid-2011, and I haven't stopped yet. Not only is it a good multi-purpose product for cleaning and maintaining my poppers, I've even used it to clean guitars. A little bit on a paper towel will do some fine cleaning, and it provides better corrosion protection than it has a right to.
Oh, and the one "con" I listed in the review - that it doesn't include a squirt tube - may just be moot. I received a multiple-can order of the stuff after the review was published, and every can had a squirt tube rubber-banded to it.
