3780. To remove Ink Stains from Wood, &c.—As much oxalic acid as will lay on a sixpence, dissolved in a tablespoonful of hot water; lay some on the wood, and rub hard with a cork until the stain disappears; then wash and repolish. The above will remove the stain, without injury to the color of the wood, mahogany or any other kind. It also cleans the brass-work.
3781. To Clean Plate.—Take of cream of tartar, alum, and common salt, each an ounce, and boil in a gallon of water, throw the plate in and boil; when taken out and rubbed dry it will look beautiful. Plate, when laid aside, will generally tarnish, but if cleaned by this method, at stated periods, it will always look well.
3782. Washing Paint.—The best method to wash paint is to rub some Bath-brick fine, and when you have rubbed some soap on the flannel, dip it in the brick. This will remove the grease and dirt speedily, without injury.
3783. Glue Paste.—Instead of pure water for mixing the flour, use glue-water, to which add some alum and resin to keep it from turning. It must be made very thick.
3784. Whenever oil is used for the purpose of artificial light, it should be kept free from all exposure to atmospheric air; as it is apt to absorb considerable quantities of oxygen. If oil is very coarse or tenacious, a very small quantity of oil of turpentine may be added.
