Depending on the ingredients used, the cooking process, how far a room sits from the activity area, and how long that activity went on, a single property can carry a wide range of contamination levels from room to room. The MethSan system is built around that variability rather than assuming one strength suits everything.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat makes the system different\u003c\/strong\u003e is that it does not rely on oxidisers alone. Alongside the oxidising chemistry that breaks down chemical and biological residues, it uses a blend of two ingredients with a strong affinity for the \u003cstrong\u003emicro-carbon soils\u003c\/strong\u003e produced when hydrocarbons and other chemicals are heated and cooked. That pairing releases and suspends soils that have embedded themselves into paintwork and porous surfaces — which is where meth residue characteristically hides, and why surface wiping alone does not resolve it.\u003c\/p\u003e\n\u003ch3\u003eWhich pack size do you need?\u003c\/h3\u003e\n\u003cp\u003eThis is the \u003cstrong\u003e5 litre\u003c\/strong\u003e pack, suited to a single property.
