Winter prep can mean lots of things, but for me it's whipping up a batch of home-made hand cream. I need it, too. As soon as the weather gets anything like cool, I develop nasty splits at the corners of my fingernails because my skin gets dry.
Long before my sensitivities to scented stuff, cleaners, etc. got so bad, I was turned off by the smell/fumes of such things. I found out about the book, Better Basics for the Home. I bought a copy, and it was money well spent.
One of the "recipes" is for Basic Waterless Wax Formula. It's meant for wood furniture, and the first time I made a batch of the stuff and polished some furniture, I couldn't fail to notice how good "BWWF" felt on my hands; better than any commercially available cream or lotion that I'd ever tried. It smelled a lot better, too.
Since that day I've never wanted to use anything else on my hands. I've tweaked the original formula to include a little bleached carnauba wax; that makes the cream a bit stiffer, so that it doesn't get too soft quite so easily. Even if it did get too soft, probably all I'd need to do was to heat it until it liquified, and then beat it with a fork until it re-emulsified.
The drawback is that BWWF keeps only three or four months. After that it starts to smell "off", like it was getting stale. I make it in small batches, because a little goes a long way. And it is kind of greasy, I admit. But it's not difficult to make, and is well worth the making.
