Works great for shotguns!
I was a bit apprehensive because no where do you really see that its good for plastic removal. Plus none of these reviews really seem to mention shotguns. I shot 250 shells out of O/U Citori yesterday. Dirty cheap shells. The foam didn't change colors at all, but it was clean as a whistle after only two passes of a brush and  two patches on a jag. Followed it up with a bore snake just cause, lubed, done. The smell is a bit stronger than most of tried. And to be fair I did wait the half hour it says to. I've never waited that long. Perhaps Hoppes or others would compare after 30 minutes, but I will continue to buy these. The "tube nozzle" is nice too, helps you know you have a good slug of foam sliding down. It stays foam longer than every other foamer I've tried too. Only real gripe is the time you have to wait. And that two cans came loosely packed in a bubble envelope which of course meant one of them sprayed a little in there and they are both moderately dented. But I wiped em down and rinsed off the cans, all is well. Just expect to get these in fair to poor condition. I plan to try shortening the soak time and seeing how it goes, but even at the 30 minute wait time, I am very pleased.
