If using Linseed or Danish oils, pour a small amount of the oil directly onto the worktop surface and using the lint free cloth, spread it over the surface until you have a very thin and even layer that covers the whole of the worktop.
For Hardwax oils follow the same process but use a suitable paint brush and ensure each coat is as thin as possible.
Once you have the thinnest possible layer of Wax or Oil, allow to fully dry before commencing a second coat, never over brush the wet surface.
