LInseed oil to protect Egg table?

I take any advice from people at Home Depot with a heavy dose of salt, since they've frequently given me completely wrong information, and in at least one case, dangerous advice ("You don't need a current tester- just touch the wire with your fingers to see if it's live. 120v won't kill you.")

However, in this case, they're right- linseed oil can promote mildew. Here's a report from the Department of Agriculture on wood finishing. Your best bet is a water-repellant finish. Some contain fungicides that will also help prevent mildew. You may want to reapply it more frequently than once a year if you're seeing severe conditions. Someone else might recommend a specific brand- I'm not in your area and can't vouch for any particular product.

I like to use Watco Teak Oil, wipe on and re-apply as needed. Water is the enemy of all wood so keep your table protected-not sitting on a damp patio but up on wheels or spacers if no wheels and covered out of the rain. When the wood is kept dry your table should last many, many years.
