Wood is a natural product, easily harmed but with a little effort it can be kept in great condition for years and years.
taking care of your Was-A-Log products
The golden rules of taking care of wooden products is to avoid sudden and large changes in temperature and humidity. Keep your products away from radiators and heat sources and don't let them sit in water.
For objects like spoons and rolling pins just wash in warm water and dry immediately. Don't ever put them in a dish washer as the high temperatures used will quickly damage them.
There is some debate as to what is the best way to treat wooden treen for food. Treen is any functional wooden object like spoons, bowls, rolling pins etc. It is normal to coat them with an oil that will penetrate the surface of the object and offer protection of some kind. An untreated dry spoon or bowl etc will quickly absorb any liquid and to stop this the object can be wiped over with an oil and wiped off after some hours. Some people dip the objects into warm or hot oil, the heat makes the oil less viscous and helps with penetration into the woods surface. Whichever method you adopt it is important to choose your oil carefully.
The best oils are those that dry after a period of time, some don't dry and can go rancid (just smell some old salad bowls that have been treated with olive oil)
Below is a guide to choosing your oil
Olive oil: Never use olive oil on treen as is doesn't dry i.e. it stays in a liquid form and can go rancid
Raw linseed oil: Also known as flaxseed oil. This is very popular but try to get cold pressed, some linseed oils can give a yellow hue to the wood.
Walnut oil: This is my personal favourite but anyone with allergy issues should probably avoid this.
There are two general kinds of oil for use with wood work: those that dry (polymerise) and those that don't.
Among the drying oils, which form a tough, plastic-like barrier. Raw linseed oil is common – make sure to avoid "boiled" linseed oil, which contains additives which help it dry faster, but can be unpleasant.
Not all oils are good for woodwork, though. A lot of vegetable oils go off (rancid). Olive oil, for example doesn't work.
For non treen objects I would not use a silicon based polish or spray, they are quick and convenient but my recommendation is to use a wax or paste sparingly, I recently read that the National Trust leaves some of it's wooden objects and architecture, like staircases, for several years between waxing.
If non treen wood is polished correctly, you can get away for several years with simply dusting it.
