I’ve found that oiling boots is a chore that keeps getting put off, because people don’t want to go get the stuff needed to do the job, and most methods are time consuming. Well, this method is really fast and easy.
The trick is to use a brush instead of a cloth, and to keep the brush in a pan of oil all the time. The pan is a low cost, like less than $2 new, baking pan. The oil is Neatsfoot oil that I buy by the gallon. It’s a better price that by the quart. The brush is a cheap bristle brush that most people consider disposable. This one has lasted for months immersed in oil, with no sign of falling apart. The aluminum foil is a folded over double layer, this is to keep dust out.
This will extend your boot life, and is wa-a-a-ay easier than anything else I’ve done.
