A bottle of olive oil, a bottle of alcohol, some new or perfectly clean canton flannel, a perfectly clean chamois leather, and a basin of water will be needed to clean a piano.

1. Wet a small piece of the flannel and drop on it a few drops of oil. 2. Rub, with the wet flannel, a small section of the case at a time, and immediately rub it thoroughly with a dry piece of the flannel, before proceeding to a fresh section. 3. Polish it finally with the chamois or a fresh piece of the flannel. Rub with the grain of the wood, and breathe on it occasionally to help remove any oiliness that may remain. A very little flour rubbed with the grain of the wood will also help to remove oiliness, but its use should not be necessary. 4. Wash the piano keys with a corner of the flannel wet with alcohol. Be careful, however, to avoid touching the wood with the alcohol, as it will ruin the varnish.
