I stand the carrier on end and just put a few drops in, and same with the bolt.
I have used a plastic pick down inside the carrier before fto remove some very stubborn residue; don`t have that problem so bad after switching to Benchmark Powder.RRMV
Hoppes works very well. I keep an old plastic screw top pill bottle about 1/2 full and drop the bolt in overnight. As Hooked said, a few drops in the carrier does the job there, as well.
