I haven't given it much of a test as a patch lube yet, mostly because it's just one more thing to knock over at the range. If it works for me, it will be for prelubing rolls of patching or cut patches- either of which will be stowed in some small container.
For cleaning after the fact, I've tried it along some other "no water" BP cleaners (Butch's, LV, alcohol, windshield washer fluid, etc) for situations where I can't do my prefered bucket of water routine. It takes a lot more patches dampened with Hoppes to get a clean patch than any of the others, including a patch dampened with plain old water. Does a good job, but just needs more time and effort to do it.
