ABSTRACT:
Chemical deterioration of permanent applied ceramic or colored labels of bottles cleaned in a bottle washer is minimized by soaking the bottles in a highly caustic composition which does not include any phosphorus compounds, ethylene diamine tetraacetic acid or nitrilotriacetic acid. The soaking composition includes the sodium hydroxide dissolved in water, in combination with polycarboxylic acid crystal growth inhibitors. Preferably the soaking solution further includes a chelant such as a gluconate, glucoheptonate, or boroheptonate. The soaking solution can be added by either combining a liquid or powder built detergent composition which also forms a portion of the present invention or, alternately, an additive package, not including the sodium hydroxide, can be added.
