My dad used to cast his boolits all the time when I was young, he loved Lyman moulds and I used to watch him put them in hot dish soap water and clean them with a toothbrush, then dry them off and put them in the oven for about 10 mins, then when they cooled off he would oil them up and put them away. Well I really like the NOE moulds, and even though they’re aluminum I still clean them after every use the same way my dad did, but one of my moulds has a little discoloration, and I’d like to get that off so it will be shiny again, the washing drying and oiling keeps them working great but it doesn’t take any discoloration off the mould, so what’s the best way to remove any discoloration?
Thanks,
Paul
