What I’m doing is building a cover for a grill top (like what would be used in a food truck) to cover and protect the grill when it’s not in use. I have been told to use peanut oil to seal the wood, but I don’t want to cause any issue with those who have allergies to peanuts.

What is the best method to seal this wood so that I can keep the cover protected and keep the people protected who eat from this grill once it’s had the cover on it? I’ve been told that Vegetable Oils can go rancid after a while on wood unless it’s had a good seal on it.

There is a lot of debate about this topic, food safe finishes, from what I have read once a finish is fully cured, it is safe.

Especially as just a cover over a grill, use any finish that cures. As long as the grill has cooled before putting the top on it, no problem. If you want it to last use something with pigment that will block UV (I assume it will be exposed to sun all the time).

I read an article by the FDA a while back – didn’t save the link – but it stated as BLarge just said that almost any finish is food safe once it is cured. That said I would never use something like peanut oil as it does not cure hard. Many oils will go rancid over time, I’d stick with food grade mineral oil( non-curing oil) or a true tung oil. I finish all my cutting / serving boards with a mix of mineral oil and bees wax, inexpensive,looks great, easy to apply and reapply as needed.

I have a rather large surface area that I’m covering, but it is out of sun. I will try the mineral oil with bees wax… seems as though I keep coming across that suggestion. Thanks.

Does tung oil give a small tint or color?
