Freshly slaked limewash, to each bucketful of which is added at least 21b. of common washing soda, makes a good paint remover. It should be applied by means of common fibre brushes - not bristles; several applications may be necessary to remove the paint. The latter should be removed by scraping when soft, then swilled off with plenty of clean water, and finally brushed over with common malt vinegar. It is doubtful whether, after this treatment, the boards will be sufficiently clean to be left as white without bleaching. For the latter, frequent applications of oxalic acid - 2 oz. to l pt. of water - will generally suffice. Partially to remove the black so as to gain an old oak effect, try equal parts of turpentine and methylated spirit. If this can be made hot with safety it has greater penetrating power. Liquid ammonia is also effective, but is best handled if diluted with an equal bulk of water.
