How does the Neutrasol Methamphetamine Decontamination System work?
To gain an understanding of how Neutrasol works we first need to understand a little about the surfaces that require cleaning and the nature of the methamphetamine(meth) contaminants.
Methamphetamine in its natural state is a solid. Through the smoking process, it becomes a hot vapour (gas) which turns back to a solid state once it cools on a surface.
During the process of changing from a vapour back to a solid it can form strong bonds with the surface. In some situations, it doesn’t bond to the surface itself-but to soiling on that surface. In theory “a dirty house is easier to clean than a clean house” as the Meth residue sitting on a film of soil is much easier to remove.
In addition to meth residue, there can be other chemical residues. These can be in the form of impurities not removed during the cooking process or if the premises has been used for cooking there can be a range of cooking by-products. Many of these contaminants have been in a vapour form that has become airborne before settling and bonding to a surface.
In a typical meth cleanup situation, there can be a number of different surfaces that are contaminated with chemical residues. Some surfaces such as glass are easy to clean and other surfaces such as paint can be quite difficult depending on their condition. Old oxidised paint or soft acrylics and varnish can prove to be difficult to effectively decontaminate.
After the removal of all carpets and soft furnishings, the next stage in Neutrasol meth decontamination utilises the Neutrasol PREP Wash to clean down all surfaces.
This step is designed to remove any surface film or soiling and consequently any meth residue that is attached to the film or soiling. Once this first stage is complete a foam wash using Neutrasol Part A&B can be undertaken.
As with many effective cleaning processes, there are three factors that contribute to the removal of methamphetamine contamination:
1. Abrasion (Agitation)
The abrasion or scrubbing of the Neutrasol on to the surface allows any loose residue to be physically removed from the surfaces. Once removed from the surface they become encapsulated in surfactants and can easily be rinsed away.
2. Contact Time (Dwell Time)
The application of the Neutrasol Part A&B creates a blanket of foam that gives the Neutrasol extended contact time against the contaminated surface. As with many cleaning processes the longer the contact time the less abrasion or mechanical effort is required.
Painted surfaces can absorb the meth residue-however, the foam blanket keeps the surface moist whilst drawing the chemical residues backout from the surface.
In situations where the contaminated surface has been painted in an attempt to cover the problem, the meth residue can naturally migrate through the new paint to give a positive meth test...
Neutrasol can draw the residue through the new paint. This takes time and the stability of the Neutrasol foam blanket is such that the foam can remain intact for as long as 24 hours depending on ambient conditions.
3. Chemical Reaction
The Neutrasol contains a light oxidizer (optimized hydrogen peroxide 3-4% in dilution) and blend of surfactants.
This combination causes a chemical reaction at the surface that releases any residues that have not been abraded from the surface.
Methamphetamine is not readily dissolvable in water but the combination of the actives and surfactants in Neutrasol allow the contaminant to be released from the surface, encapsulated in the surfactant foam and easily rinsed away.
