Walked thru local Walmart this morning, the Hoppes Copper Terminator was cut from $8.97 to $2.50

Never tried it.  Got a bottle to try....

Doesn't smell at all, probably not worth a crap! lol

fwiw

Thought I'd give an update.

Been cleaning an AR I took to the range last weekend, I run a patch wet with Copper Terminator, let it sit for a day then a dry patch to see how it goes. If you're use to the old Hoppes green, you'll notice this gunk comes out a dark shade of brown. Odd, another online review says patches come out the old green.....dunno. I'll try some copper overnight and see what's up.

In short, I like it so far, it is odorless, wife said wow! , does the job, and it is a lot thicker than the original Hoppes. But with Walmart discontinuing it, it may not be around much longer though it is still on Hoppes website.
