Using tongue oil as the conditioner

Q: We have 8 wooden chairs with rush seating. They were left on a covered porch in the rain and a serious mildew(ing) occurred. I have cleared the problem with a 15% bleach/85% water solution and they are looking very good. My next move will be to soak them with a mildew-resistant sealer, but first I would like to apply some type of conditioner/moisturizer.

Do you have any suggestions? The actual rush seems to be a natural fabric. Someone suggested using tongue oil as the conditioner before the sealer is applied. What do you think?

A: With a tung oil based product such as Waterlox, you would get excellent penetration and moisture protection.
