Specialised Clandestine Drug Lab Decontamination Pre-Treatment

Actichem MethSan PreWash (DR634.20) is an advanced, high-performance alkaline pre-wash detergent specifically engineered for the professional remediation and decontamination of properties contaminated with methamphetamine and illicit drug manufacturing residues. In clandestine drug lab clean-ups, stubborn carbonaceous films, grime, and synthetic chemical oils bind tightly to building surfaces. MethSan PreWash is purpose-built to break down, penetrate, and emulsify these heavy surface contaminants prior to main wash decontamination.

Core Role in the MethSan Remediation System

In professional meth remediation protocols, applying an effective pre-wash is often the defining factor between passing or failing clearance testing. MethSan PreWash serves as Step 1 in Actichem's proven multi-stage decontamination system:

• Step 1 (Pre-Treatment): MethSan PreWash breaks down surface hydrocarbons, chemical films, soot, and micro-carbon compounds, preparing the substrate for deep chemical neutralisation.
• Step 2 (Main Decontamination Wash): MethSan Part A combined with MethSan Boost (Fog Boost or Foam Boost) directly oxidises and degrades the remaining embedded illicit drug compounds.

Key Applications & Compatibility

Actichem MethSan PreWash is formulated for use across commercial, residential, and industrial remediation environments on washable architectural surfaces, including:

• Interior painted drywall, plasterboard, and masonry
• Concrete flooring, ceramic tiles, and industrial hard surfaces
• Kitchen cabinetry, range hoods, benchtops, and exhaust systems
• Framing timbers, structural supports, and subfloor assemblies

Recommended Directions for Use

• Pre-Testing: Always pre-test surface sensitivity and colourfastness in an inconspicuous area prior to broad application.
• Dilution Ratio: Dilute 1:4 with clean water (e.g., 200 mL of concentrate per 800 mL of water, or 1 L concentrate per 4 L water).
• Application: Apply evenly to affected surfaces using a low-pressure chemical sprayer, industrial sponge, or mechanical scrubber.
• Agitation & Dwell Time: Agitate thoroughly using appropriate scrubbing pads or brushes. Allow a dwell time of 10 to 20 minutes to penetrate embedded deposits. Ensure the product does not dry on the surface during dwell time.
• Rinsing: Thoroughly rinse the surface with clean water to extract emulsified soils. Allow surface to become touch-damp (not shiny-wet) before proceeding to Step 2 (MethSan Part A).
