Creosote is forced into the timber under pressure to preserve the
wood, the only cure is time, and we are talking many many years here.

All the gasoline would do is wash off the surface, it would soon be
replaced by more creosote oozing to the surface.

Mr. Fouchey said it right, nothing you can do will prevent the
saturated creosote from oozing until it is ready to. One problem with
using them for steps is getting the creosote tracked in to the house.
