NOTE: for dining chairs we recommend removing the seat when oiling to avoid staining the fabric.
If you protect the leather against too much heat, very dry air, direct sunlight and chemicals, the soft leather will be a source of comfort for years.
Regular dusting with a soft cloth and vacuum cleaning are all that is normally necessary. However should the surface be noticeably soiled then the surface should be cleaned.
Do not attempt to feed the leather with saddle soap or use wax soap and never use spray or hide polishes that can cause deterioration and create an unpleasant sticky surface
