To clean them? If you strain the oil from the deer fat, or the liquid wax from the raw beeswax, through a strainer with cheescloth in several layers and coffee filtersin the bottom of the strainer, you should catch 99.9% of all foreign matter that might be present in each. Most of the foreign matter will float to the top of the rendered liquids and can be skimmed off with a spoon.
Use a double boiler arrangement with each, which means, put whatever pan in which you are " boiling " the fat or wax, in a second pant that has at least one inch of water in it. The lower pan boils water at 212 degrees, well below the flashpoint of either of the oils, but above their melting temperatures. THIS IS A SAFETY MATTER, and should never be skipped. I use a skillet with water in it on the fire, and then use a saucepan to actually contain and melt the wax or fat. I use a large spoon to press more rendered fat or wax out of my cheesecloth so I don't waste it. ( I am cheap!) :shocked2:
Use a measuring cup to measure your proportions for best results. Later, after you have done it a lot of times, you can probably do it by eye just as well. What ratio are you planning to use for combining the two products? A 1:1 ratio( half and half) seems to work okay as a patch lube.
