This is a cheap method of removing old paint from Venetian blind laths. Place 1 stone of well-burnt lime in a large bucket and slake with hot water; add 71b. of common soda, and stir the whole together until the soda is dissolved. Lay this solvent over the laths about 1/4 in. thick, and allow it to remain about two hours; the paint can then be easily scraped off. Thoroughly wash off with clean water and dry. Coat the laths with vinegar before re-painting.
