I use the LEM cleaner and pins , But found a after re sizing some Martini Henry cases the cleaner was slow to clean and cases were left dull, this was due to the amount of lube left on the cases ( as baldie points out ) This left the pins almost black with lube, so I ran the cleaner with hot water and a dishwasher tablet result pins like new. The next batch of 308 case were cleaned with hot water and dishwasher tablet ( the cheap ones £2 for 40 ) this reduced cleaning time and I think the brass is cleaner, swilled in rinse aid and drained then fruit drier .
