Citric acid and sodium carbonate are the preferred acid and carbonate salt. In a preferred embodiment, urea is added to the acid solution to prevent yellowing and to improve cleaning ability. The compositions are preferably prepared and applied at an elevated temperature in the range of between about 140.degree. and 200.degree. F.
