I don't usually go to Ikea looking for woodworking advice, but I stopped by today, to look at their hardwood countertop material. The clerk told me I needed to buy some of their special oil, and to make sure to oil the countertop within a day of unwrapping it.
The wood was shipped dehydrated, you see, and if you didn't oil it immediately - before sawing it, drilling it, or sanding it - it would crack.
I looked at their "special" oil. It's a mix of tung and linseed oil.
Is there any basis to this whatsoever?
