393. Cleaning Japanned Waiters, Urns, &c.--Rub on with a sponge a little white soap and some lukewarm water, and wash the water or urn quite clean. Never use hot water, as it will cause the japan to scale off. Having wiped it dry, sprinkle a little flour over it; let it remain untouched for a short time, and then rub it with a soft dry cloth, and finish with a silk handkerchief. White heat marks on the waiters are difficult to remove; but rubbing them with a flannel dipped in sweet oil, and afterwards in spirits of wine, may be tried. Waiters of papier maché should be washed with a sponge and cold water only, and dredged with flour while damp. After the lapse of a few minutes the flour must be wiped off and the article polished with a silk handkerchief.
