The document then offers techniques for the cleaning of speciﬁc items and materials found within a former meth lab (e.g., walls, ﬂ oors, appliances, electronics, fabrics, toys). Finally, this document provides detailed information on sampling techniques and methods. Additional information and resources are included in the appendices.
