If you don`t have any Ballistol, a light gun oil works. I use Rem oil and it costs less than Ballistol.
I hate to start something on this forum, because this subject matter always generates great opinions and causes strong words, but I just can't resist, so here I go. Please don't kick me off of the forum over this but...........
Ballistol is a TERRIBLE thing to use on firearms and aluminum, because it forms a "harz" or resin on the item that is very hard, and very difficult to remove. My son is a German Master Gunmaker, and when we are in the company of his gunmaking friends, the conversation about Ballistol, usually comes up. They all start cussing, because Ballistol has such a good marketing department, and every German hunter slathers that stuff all over their guns and slings. After a few years, it forms into a yellowish resin, and is very hard to remove from the metal, and gums up the sandpaper when used on wood. It creeps down into the action, and gums up triggers and springs. After a few years, it actually makes leather brittle.
But the Ballistol marketing team says exactly the opposite, and market it as a non-resinating coating, and a leather softener. It is neither.
In the 1970s, they also marketed it as an aluminum preservative, and many motorcycle owners started putting it on their aluminum rims, carburetors and motor blocks. I can't tell you how many Bing carburetors and BMW /2 and /5 rims and hubs I've seen with a dirty yellow, almost unremovable, coating of resonated Ballistol I've seen over the years. My Avatar of the BMW R24 (not mine, but I do own one) should indicate that another of my hobbies is old BMW motorcycles.
But please, use anything but Ballistol on something you want to cherish. The only thing I used to use Ballistol for, was to clean my hunting dogs ears, and wipe his paws off with it when we went for a walk on a salted road in the winter. My son would scold me when he saw it on my workbench, until I told him what it is used for. Since my dog died a few months ago, all of the Ballistol went into the trash.
Please don't be too hard on me.
