LIME WATER

Lime water is a weak solution of lime putty dissolved in water used in decorating for washing down painted surfaces prior to repainting. Lime water is less aggressive towards grease than sugar soap, but less harmful to existing paintwork. Care should be taken not to allow the lime water to dry, but rather to rinse it off with clean water, lest the lime remains and reacts with the paint later applied.
