Here is an in depth description on how to make the best spray on lube:
You need to buy 3 things. First, you want to get pure liquid lanolin. It can be bought online on Amazon.com and looks like this: (

Next, you need to buy a 12 oz. bottle of 99 percent isopropyl alcohol. While many stores carry isopropyl alcohol in their drug/cosmetic isle, I have found few that carry the 99 percent variety that you need. Fortunately, there is an easily found product that contains 99 percent isopropyl alcohol: Iso-HEET Injector Cleaner & Fuel Line Antifreeze. Make sure it is the red bottle HEET and not the yellow bottle HEET, as that contains methanol and not isopropyl alcohol.
Lastly, you need a spray bottle. I bought mine at a Dollar General store for about 2 bucks. Now for the mixing. You need to warm both the lanolin and the HEET to enable them to mix together. But, you cannot do this over an open flame.
Again, do not heat either the lanolin or the HEET over an open flame. Rather, bring a pot of water on the stove to a boil and then turn off the heat. Then, insert the bottle of lanolin and the bottle of HEET into the boiling water until both are quite hot. After removing them from the water, with a pen or magic marker, mark the lanolin bottle in increments of 1 oz. In other words, if the height to the top of the lanolin in the bottle is 4 inches, from the bottom place a mark 1 inch up, 2 inches up, and 3 inches up. Actually, it is probably better to do this prior to heating the lanolin. So now, with both the lanolin and the HEET hot, pour 1 oz. of the lanolin and the entire 12 oz. bottle of HEET into your spray bottle. Shake it up and look for an even mixing taking place. If you see separation of the two, place the spray bottle into the hot water to heat up the mixture and shake again.
To apply the lube, it’s best to place your brass into something like a 1 gallon ziplock bag, give a couple of squirts, close the bag and then shake the bag so the lube gets distributed onto all your brass. You can also spray the inside of the bag a couple times and then put the brass in prior to shaking them.
After resizing the brass, you will need to remove the lube. The best way to do this is to place them in your dry tumbler, add about a tablespoon of mineral spirits/paint thinner, and then tumble them for about 20 minutes. Hope this has been helpful, and if you have any questions, please don’t hesitate to ask.
