Oil from the seeds of Camellia japonica is the traditional Japanese choice for protecting tools from rust: use it when cleaning, and as a regular protective coating. Leaves a lovely deep, non-oily finish, and it's odourless and tasteless (handy for kitchen knives, but don't try drinking it.) 100ml- will last for years unless you drink the stuff ( but don't, it's mixed with paraffin). Unfortunately, we cannot send this to customers in the USA.
