The present study was undertaken to evaluate the effectiveness of washing with cold water to eliminate glyphosate residues absorbed on work garments.

The experiments were performed on work trousers and overalls using both technical glyphosate and the commercial formulation VISION^™. During these experiments, the glyphosate concentrations were determined in the wash and rinse water and also on the contaminated pieces of fabric. For the last two experiments, glyphosate concentrations were measured in the soak water. All washes were carried out using cold water in a domestic washing machine. The results indicate that glyphosate was quickly removed from the clothing, and generally, was not detected in the rinse water. Subsequent measurements of residual glyphosate on garments show that the effectiveness of washing in cold water is generally greater than 95%. As appears from this study, cold water washing or a prolonged soaking efficiently removes glyphosate from work garments.
