I am asking for suggestions for removing old varnish from an interior oak staircase. The staircase has treads, banisters, pedestals, and carved trim molding. The varnish is about 30 years old, and is very dark, almost black.
On the Newton project, I saw Jim Clark use a blue paint stripping liquid to remove old varnish. Does anyone know what he used?
Would I be better off to use a mechanical sander instead of a paint stripping liquid?
