The advantages of dilution are that the mixture penetrates the wood better, leaves a thinner film on the surface and is more economical.

Then rub, rub, rub, day after day.
Little and often with unlimited friction, is the best rule.

This makes a nice finish for well-fumed chestnut, turning the color to a rich brown.
(b) _Wax._ Wax is an old English polish, commonly used before French polish and varnish were introduced, especially for hard woods like oak.

Its advantages are that it is cheap, easily prepared, easily applied, and easily repaired.
