It is better to wash windows on a cloudy day or when
the sun is not shining directly on them. Before washing, dust them
thoroughly inside and out, then wash the woodwork without touching the
glass. For the glass use warm water, to which add a tablespoonful of
kerosene to each pailful of water used. Dry with a cloth or chamois skin,
wrung very dry; then polish with a soft cloth or soft old newspapers.
