Bleach and commercial cleaners like Crystal Clear have been used with varying success to remediate meth contamination in rental properties, but many find them insufficient. Alternative suggestions include using solvents like acetone or naphtha, which can dissolve organic residues, and vinegar mixed with soap to help make meth residues more soluble. Ozone generators may also assist in breaking down meth compounds, although their effectiveness is debated. The discussion highlights the challenges of cleaning ductwork and hard surfaces, emphasizing the need for effective solutions that can remain on surfaces longer. Overall, a combination of methods, including scrubbing and chemical treatments, is suggested for thorough remediation.
